Introduction: Why Do the Twenty-Four Solar Terms Have "Small Fullness" but No "Great Fullness"$1

Between Heaven and Earth, all things have their season. When we open a calendar today and see the two characters Xiaoman (小满, "small fullness") resting quietly in some square of late May, most of us think only of this: the weather is turning warm, and the wheat will soon ripen. Yet such an understanding does a disservice to the profound wisdom carried within these two characters. Xiaoman is by no means a simple marker of the farming calendar. It is a subtle realization, by our ancestors, of the Dao of waxing and waning that governs Heaven; it is the most understated yet most profound answer that Chinese civilization has given to the eternal temptation of "fullness."

Let us first pause over a fact that seems simple, yet is in truth startling: among the twenty-four solar terms, wherever there is a "small heat" (小暑) there is a "great heat" (大暑); wherever there is a "small cold" (小寒) there is a "great cold" (大寒); wherever there is a "small snow" (小雪) there is a "great snow" (大雪). Only "small fullness" stands alone—there is no "great fullness."

Why should this be so$2

Did our ancestors simply overlook it$3 Was the calendar left incomplete$4 Neither is the case. In an age when the observation of astronomical and phenological phenomena was calibrated to the precision of "five days make one pentad" (五日为一候), in an age when even a mole cricket's cry sounding three days early or three days late was dutifully recorded, it is inconceivable that a solar term could have been omitted by oversight. The absence of "great fullness" is not an accident but a necessity; not an omission but a deliberate choice. When our ancestors came to name this crucial stretch of the year in which Heaven and Earth move from "approaching fullness" toward "utmost abundance," they deliberately and consciously stopped at "small fullness"—stopped precisely at that threshold of "having attained a small fullness" but not yet "great fullness," and refused to take one step further.

Why refuse to take that further step$5

Because in the cosmology of the ancient Chinese, "fullness" (满) is a character fraught with peril. What is full must eventually diminish; what overflows must eventually spill; what reaches its utmost flourishing must eventually decline; "the arrogant dragon has cause for regret" (亢龙有悔)—this is the most impartial law by which the Dao of Heaven operates. The "Commentary on the Judgment" (Tuanzhuan) of the hexagram Qian (谦, Modesty) in the Book of Changes (Zhouyi) states it without equivocation: "The Way of Heaven diminishes fullness and augments modesty; the Way of Earth alters fullness and directs it toward modesty; ghosts and spirits harm fullness and bless modesty; the Way of humanity detests fullness and delights in modesty" (天道亏盈而益谦，地道变盈而流谦，鬼神害盈而福谦，人道恶盈而好谦). Heaven, Earth, the spirits, and humanity—not one among these four fails to "detest fullness." Under such a Dao of Heaven, "great fullness" is not a consummation worth pursuing, but an omen of imminent collapse. Our ancestors would rather let all things pause forever at "small fullness"—at that state brimming with vitality, full of promise, yet still modest, reserved, and leaving room for what comes after—than let things advance toward that seemingly perfect but truly precarious state of "great fullness."

This is the hidden mechanism behind "small fullness with no great fullness." This one small act of naming crystallizes the very core of Chinese civilization's value orientation: to prize modesty, to guard against fullness, to treasure the mean, and to preserve incompleteness. The line from the "Counsels of the Great Yu" (Da Yu Mo) in the Book of Documents (Shangshu)—"fullness invites loss, modesty receives gain" (满招损，谦受益); the line from Laozi's teaching—"to hold a vessel and fill it to the brim is not as good as stopping in time" (持而盈之，不如其已); the line from the top line of hexagram Qian (乾, the Creative) in the Book of Changes—"the arrogant dragon has cause for regret" (亢龙有悔); and even the sigh recorded in the Xunzi, attributed to Confucius on beholding the "vessel that tilts when seated in honor" (宥坐之器)—"how could there be a thing that, once full, does not overturn$6" (恶有满而不覆者哉)—all of these distillations of pre-Qin wisdom have, it turns out, been quietly and unobtrusively sealed within the name of a single solar term.

The "Canon of Yao" (Yao Dian) in the Book of Documents records: "Then he commanded Xi and He, in reverent accordance with the vast Heaven, to calculate and delineate the sun, moon, and stars, and respectfully to bestow the seasons upon the people" (乃命羲和，钦若昊天，历象日月星辰，敬授民时). When our ancestors observed the heavens to determine the seasons, they were never doing so merely to know when to sow and when to reap. In their eyes, every solar term was an "utterance" of the Dao of Heaven, and the name of every solar term was a "crystallization" of Heaven's intent. And the intent crystallized in the name "Xiaoman" is precisely this: the fundamental Chinese attitude toward "success," toward "fullness," toward "completeness"—full yet not overflowing, brimming yet able to remain empty, approaching fullness but not yet full, always leaving room for what comes next.

This article will proceed from the core thought of the pre-Qin Confucian and Daoist schools, tracing back to the myths and ritual institutions of high antiquity, to offer as deep an interpretation as possible of the solar term Xiaoman. We seek not only to know what Xiaoman is, but to ask why it is a "small" fullness rather than a "great" one; not only to understand what the ancients did during Xiaoman, but to grasp what spiritual code of a whole civilization lies hidden behind this singular act of naming. In the course of this layered inquiry, perhaps we can once again touch that ancient world in which all things possessed spirit, Heaven and humanity resonated with one another, and fullness was, at every turn, held in wary regard.

Chapter 1 · The Original Meaning of "Man" (满): A Universe of Waxing and Waning Contained in a Single Character

I. Why Is "Man" (满, "Full") Called "Man"$7

Before entering into the specific discussion of Xiaoman, we must first fix our gaze on the character "man" (满) itself. Why was this character chosen to name this solar term$8 What is its original meaning$9 And how has it come to bear so weighty a philosophical burden$10

The character man (满) is composed of the radical for "water" (水) alongside the phonetic component man (㒼). Although the Shuowen Jiezi (Explaining Simple and Analyzing Compound Characters) is a work of the Eastern Han, the traditions of character meaning it records can be traced back to pre-Qin times. The Shuowen glosses man as "to be full to overflowing" (盈溢也), noting: "It follows 'water'; man (㒼) gives the sound." The "water" radical points to the most primal image behind man—water within a vessel. As water is poured into a container, it gradually rises until it reaches level with the rim: this is man, "full." If more is poured in, the water crosses the rim and spills over: this is yi (溢), "overflow."

Note the subtle principle embedded in this image: "fullness" is a threshold state. It sits upon that exceedingly fine line between "not yet full" and "overflowing." Water that has not yet reached the rim is "empty" (虚), "deficient" (亏), "not full." Water level with the rim is "full" (满). Water that crosses the rim is "overflow" (溢), "excess" (过), the beginning of calamity. From the moment of its birth, the character man has stood upon a perilous edge—it is the very peak of abundance, and also the eve of overflow.

This is why "fullness" in Chinese culture has always carried a tinge of wariness. The Shuowen glosses man as "full to overflowing" (盈溢), and the two characters ying (盈, "brimming") and yi (溢, "overflowing") themselves hint at the danger of excess. A person who truly understands the original meaning of man, on seeing water about to reach the rim of a vessel, feels rising in their heart not satisfaction and joy, but a kind of vigilance—just a little more, and it will spill over.

II. Why Is Xiaoman "A Small Attainment of Fullness"$11

The Collected Explanations of the Seventy-Two Pentads of the Monthly Ordinances (Yueling Qishi'er Hou Jijie, compiled by Wu Cheng of the Yuan dynasty, gathering the tradition of monthly ordinances from Han and Wei times onward) offers an extraordinarily apt explanation of Xiaoman: "In the middle of the fourth month, Xiaoman means that things have, by this point, attained a small fullness" (四月中，小满者，物致于此小得盈满).

Let us savor these eight characters carefully—wu zhi yu ci xiao de ying man (物致于此小得盈满).

Wu (物, "things") refers to the crops that ripen in summer, wheat above all. Zhi yu ci (致于此, "have reached this point") means that the growth of all things has arrived at this particular juncture. The four characters xiao de ying man (小得盈满, "a small attainment of fullness") are the crux of the whole phrase—not "a great attainment of fullness," not "an already-attained fullness," but "a small attainment of fullness." By the time of Xiaoman, the kernels of wheat have begun to fill out, to become substantial, to grow plumper day by day—but they are not yet fully ripe, not yet at that heavy, golden, harvestable state of "great fullness." They are only "small"ly full—just beginning to fill, showing the first signs of plumpness, their future bright yet still requiring time.

What a precise and poetic act of naming this is! Our ancestors did not wait until the wheat was fully ripe before naming this period, nor did they rush to name it the moment the wheat first put forth its ears. Rather, they captured precisely that subtle moment when "the kernels have just begun to fill, the grain-filling has only just started"—that moment brimming with hope, yet still restrained, not yet willing to reach completion.

Why were our ancestors so devoted to this moment of "approaching fullness but not yet full"$12

Because in their wisdom, the most beautiful state was never "already complete," but rather "in the process of becoming complete." To already be complete means that what follows can only be decline; to be in the process of becoming complete means that everything is still growing, there is still room, still full of possibility. The "small" (小) in Xiaoman is not a deficiency but a measure of restraint; not insufficiency but reserved space. By prefixing "small" to "full," our ancestors infused this state of abundance with the wisdom of restraint—abundance is good, but it suffices to reach "small fullness"; there is no need, and indeed no permission, to pursue that perilous "great fullness."

III. From "Full" to "Overflowing": A Single Character's Difference, a World Apart

Let us go one layer deeper and explore the cosmological significance carried in that single-character difference between man (满, "full") and yi (溢, "overflowing").

In the conception of our ancestors, the whole of Heaven and Earth was itself a vast vessel, and what filled it, ceaselessly generating and regenerating, was qi (气). In spring, qi sprouts from beneath the earth and slowly rises; the vessel of Heaven and Earth gradually turns from "empty" to "substantial." By the time of Lixia (the Beginning of Summer) and Xiaoman, the yang qi is abundant and all things flourish vigorously; the vessel of Heaven and Earth has now attained "a small fullness." Were this to develop further, by the height of summer the yang qi would reach its utmost flourishing—and this would be the "fullness" of the vessel of Heaven and Earth.

The question, precisely, is this: what happens once the vessel is full$13

The Most High (Laozi) gives the most profound answer in Chapter 9 of the Daodejing: "To hold a vessel and fill it to the brim is not as good as stopping in time; to hammer a blade to its sharpest point is not something that can long be preserved. When gold and jade fill the hall, none can guard them; when wealth and honor breed arrogance, one brings calamity upon oneself. To accomplish one's task and then withdraw—this is the Way of Heaven" (持而盈之，不如其已；揣而锐之，不可长保。金玉满堂，莫之能守；富贵而骄，自遗其咎。功遂身退，天之道也).

"To hold a vessel and fill it to the brim is not as good as stopping in time" (持而盈之，不如其已)—one who holds a vessel already full, and still wishes to fill it further, would do better to stop right there. Why$14 Because to add more is to invite overflow, and once it overflows, everything spills and is lost. What a plain and yet profound principle this is! A person holding a cup already brimming with water—their wisest choice is not to keep pouring, but to stop, to "cease" (已).

The naming of the solar term Xiaoman resonates precisely with the Most High's wisdom of "not as good as stopping in time." When the qi of Heaven and Earth fills to the point of "small fullness," this is already the best state; to covet that "great fullness" would be like "holding a vessel and filling it to the brim"—inevitably leading to overflow, to decline, collapse, and calamity. That our ancestors let all things pause at "small fullness" is precisely the cosmic version of "not as good as stopping in time."

This brings us to a core proposition that runs through this entire essay: why does Chinese culture so guard against "fullness," and so exalt the state of "approaching fullness but not yet full"$15 We will unfold this question layer by layer in the chapters that follow. But already, here, we can see that a single character man and a single character xiao (小, "small") have already revealed to us a civilization's profound wisdom in facing the principle of waxing and waning.

IV. "Fullness" and "Emptiness": The Dao of Waxing and Waning in the Book of Changes

To fully understand "fullness," we must also introduce its opposite—"emptiness" (虚).

The Book of Changes (Zhouyi) speaks throughout of the Dao of "waxing, waning, and cyclical movement" (盈虚消息). The "Commentary on the Judgment" of hexagram Feng (丰, Abundance) in the Zhouyi states: "When the sun reaches its zenith, it begins to decline; when the moon reaches fullness, it begins to wane. The fullness and emptiness of Heaven and Earth wax and wane with the times—how much more so, then, for human beings$16 How much more so for ghosts and spirits$17" (日中则昃，月盈则食，天地盈虚，与时消息，而况于人乎？况于鬼神乎？)

When the sun reaches high noon, it begins to tilt westward; when the moon reaches its fullest, it begins to be eclipsed. The fullness and emptiness between Heaven and Earth rise and fall along with time—if this is true even of Heaven and Earth, how much more so of human beings$18 How much more so of ghosts and spirits$19

This passage sums up the destiny of "fullness" entire—whatever reaches "fullness" (盈) must inevitably move toward "emptiness" (虚). The sun at noon must tilt; the full moon must be eclipsed. This is the iron law of the Dao of Heaven, from which there is no escape. Once we understand this principle, the deeper meaning of "small fullness with no great fullness" becomes all the more clear. Our ancestors did not let all things advance to "great fullness" (the full moon) precisely in order to spare them from "great emptiness" (the lunar eclipse). To pause at "small fullness" is to pause at the state of "the sun not yet at noon," "the moon not yet full"—there is still room ahead to rise, and the turning point at which one must tilt, must be eclipsed, has not yet arrived.

What a superior wisdom of survival this is! It does not seek the highest point, because after the highest point one can only descend; it would rather pause at a position slightly below the summit, because there, everything is still ascending. Chinese culture's fondness for "small fullness" is, at its root, a cherishing of "upward momentum"—as long as one is still ascending, there is still hope; once one reaches the summit, hope begins to drain away.

Chapter 2 · The Astronomical Basis of Xiaoman: The Sun Reaching Sixty Degrees of Ecliptic Longitude

I. Sixty Degrees of Ecliptic Longitude: Xiaoman's Coordinate in the Sky

How did our ancestors determine the precise moment of Xiaoman$20 This question leads us into the very heart of ancient Chinese astronomy.

In today's astronomical terms, Xiaoman is the moment when the sun reaches sixty degrees of ecliptic longitude. "Ecliptic longitude" (黄经) is a coordinate that measures the sun's apparent position along the ecliptic, taking the vernal equinox point as its origin. When the sun reaches zero degrees of ecliptic longitude, it is the Spring Equinox; at fifteen degrees, Qingming; at thirty degrees, Guyu (Grain Rain); at forty-five degrees, Lixia (the Beginning of Summer); and at sixty degrees, Xiaoman. Every fifteen degrees marks another solar term, and the twenty-four solar terms divide the 360-degree circle of the ecliptic into equal parts.

What does this position of "sixty degrees" signify$21 It means that Xiaoman falls exactly two-thirds of the way between the Spring Equinox (zero degrees) and the Summer Solstice (ninety degrees)—already far removed from the equinox's balance of day and night, and rapidly approaching the solstice's longest day. In other words, by Xiaoman, the sun's position in the sky is already quite high, the days are already quite long, the yang qi already quite abundant—yet it has not yet reached that highest, longest, most abundant "extreme."

Note how precisely this astronomical state of "approaching the extreme but not yet there" resonates with the literal meaning of the two characters Xiaoman—"a small attainment of fullness, not yet great fullness"! The sun reaching sixty degrees of ecliptic longitude is precisely the astronomical portrait of yang qi having achieved "a small fullness"—it is abundant, but has not yet scaled the summit; it is vigorous, but leaves room for more. The sun in the sky above and the wheat ears in the fields below follow one and the same rhythm of "approaching fullness but not yet full." This is by no means coincidence, but a necessary consequence of our ancestors' cosmology of "the unity of Heaven and humanity"—the rhythm of waxing and waning in the Dao of Heaven runs through the sun, moon, and stars, and likewise runs through the grasses, trees, and grain.

II. Measuring Shadows with the Gnomon and Sundial: The Wisdom of a Shadow "Approaching Its Shortest but Not Yet There"

Of course, the ancients of the pre-Qin era did not use a concept such as "sixty degrees of ecliptic longitude." Their oldest method for determining Xiaoman was to observe the sun's shadow.

The Rites of Zhou (Zhouli), in the chapter "Da Situ" of the "Offices of Earth," records: "By the method of the jade gnomon, measure the depth of the earth, rectify the sun's shadow, and thereby seek the center of the earth" (以土圭之法测土深，正日景，以求地中). The gnomon-and-sundial (guibiao) is China's most ancient astronomical instrument—an upright vertical post (biao) paired with a horizontal ruled tablet (gui); by measuring the length of the post's shadow at noon, one could infer the sun's elevation and track the succession of the solar terms.

At the Summer Solstice, the noon shadow is shortest, because the sun's position is highest; at the Winter Solstice, the noon shadow is longest, because the sun's position is lowest. At Xiaoman, the length of the noon shadow falls between that of Lixia and the Summer Solstice—shorter than at Lixia, but longer than at the Summer Solstice. In other words, by Xiaoman, the shadow has already shortened to a degree close to the shortest of the year, yet has not yet reached that shortest extreme.

Here again we encounter that familiar theme—"approaching its shortest but not yet there." The shadow at Xiaoman represents the second stage of "shortness" within the year, only a step away from the "utmost shortness" of the Summer Solstice. As our ancestors observed this daily shortening shadow, not yet at its shortest extreme, they knew: the yang qi is now vigorous but not yet at its utmost, all things are now full but not yet overflowing—this is the time of "small fullness."

It is worth pondering deeply why our ancestors chose to establish a dedicated solar term precisely at the moment when the shadow is "approaching its shortest but not yet there." Why not simply wait for the Summer Solstice, when the shadow is shortest$22 Hidden here, in fact, is our ancestors' special regard for "process" rather than "extremity." The Summer Solstice is an extreme point, a turning point, the threshold at which yang qi turns from flourishing to declining; Xiaoman, by contrast, is an unhurried pause within the ascending process—here, everything is still moving toward the good, still filling up, not yet pressing against that limit at which it must "turn back" (反). That our ancestors named this unhurried moment of "still rising but not yet at the peak" reflects, precisely, their special fondness for the state of "not yet full."

III. Culmination Stars at Dusk and Dawn: The Ancestors' Method of Observing the Heavens

Besides the sun's shadow, our ancestors also determined the solar terms by observing which constellations culminated—reached the southern meridian—at dusk and at dawn.

The "Canon of Yao" in the Book of Documents records the marker culmination-stars of the four mid-seasons: "At mid-day, the Bird star culminates, to fix mid-spring" (日中星鸟，以殷仲春); "The day being longest, the Fire star culminates, to rectify mid-summer" (日永星火，以正仲夏); "At mid-night, the Emptiness star culminates, to fix mid-autumn" (宵中星虚，以殷仲秋); "The day being shortest, the Mane star culminates, to rectify mid-winter" (日短星昴，以正仲冬). Of these, "the day being longest, the Fire star culminates, to rectify mid-summer" tells us that, around the time of the Summer Solstice, the marker constellation culminating at dusk in the southern sky is "Great Fire" (大火, the star Antares).

Xiaoman falls right after Lixia and before Mangzhong, in the very midst of the approach toward mid-summer (the Summer Solstice). At dusk during this period, the star Antares has already risen to a considerable height in the sky—but has not yet reached the position of culmination it will attain at mid-summer. "Antares approaching culmination but not yet there" is, once again, a celestial phenomenon of "approaching but not yet arriving."

Why was the movement of the star Antares so important$23 The Zuo Tradition (Zuozhuan), in the ninth year of Duke Xiang, records: "The Fire Minister of the Taotang clan, E Bo, dwelt at Shangqiu, where he offered sacrifice to Great Fire" (陶唐氏之火正阏伯居商丘，祀大火). In high antiquity, there was an office called "Fire Minister" (火正), dedicated specifically to observing the star Antares. Antares appears in the east in spring, culminates at mid-heaven in summer, sinks in the west in autumn, and hides beneath the earth in winter; its cycle of rising and setting corresponds precisely to the succession of the four seasons. And at the time of Xiaoman, Antares is "approaching culmination"—precisely the celestial sign of yang qi "approaching its utmost." Our ancestors looked up to observe the height of Antares, and looked down to examine the grain-filling of the wheat ears; the two corroborated each other, confirming with certainty that "Xiaoman" had arrived. This dual method of verification—"observing the heavens above, examining phenological signs below"—embodies the plain yet rigorous empirical spirit of our ancestors' astronomy.

IV. Beyond the "Four Beginnings, Two Equinoxes, and Two Solstices": Why Was a Term Like "Fullness" Still Needed$24

In the earliest system of solar terms, there were only the "two equinoxes and two solstices" (二分二至)—the Spring Equinox, Autumn Equinox, Summer Solstice, and Winter Solstice. Later, the "four beginnings" (四立) were added—Lichun (Beginning of Spring), Lixia (Beginning of Summer), Liqiu (Beginning of Autumn), and Lidong (Beginning of Winter)—together forming the eight nodal points of the "four beginnings, two equinoxes, and two solstices." Each of these eight solar terms corresponds to a clear astronomical extremum or turning point: the equinoxes mark the balance of day and night; the solstices mark the longest and shortest shadows; the "beginnings" mark the inception of each season.

But Xiaoman is neither an equinox, nor a solstice, nor a "beginning." It corresponds to no astronomical extremum; it is merely a point on the ecliptic—sixty degrees—that neither rises nor falls, neither leans one way nor the other. Why did our ancestors establish a dedicated solar term at such an unremarkable astronomical position, and give it a name as suggestive as "Xiaoman"$25

The answer lies here: as agriculture grew more refined, the eight nodal points alone no longer sufficed. Our ancestors needed a finer scale of time to arrange their farming activities, and so they further subdivided the eight nodes into the twenty-four solar terms. In the course of this subdivision, each newly added term was given a name that most closely matched the phenological signs and farming activities of that period. And the period corresponding to sixty degrees of ecliptic longitude happened to align precisely with the critical moment when the kernels of summer-ripening crops "first begin to fill"—and so it came to be named "Xiaoman."

This act of naming reveals something profound: in the eyes of our ancestors, the name of a solar term was never an arbitrary label, but a precise distillation of the "true state of affairs" between Heaven and Earth during that period. The two characters "Xiaoman" are the poetic crystallization of the phenological reality that "the wheat kernels are filling with grain, just beginning to show plumpness." And in choosing "Xiaoman"—rather than any other term—to name this period, our ancestors simultaneously infused this name with the entire civilization's attitude toward "fullness": to esteem its "small" measure and to guard against its "great" extreme. Astronomy provides the skeleton, phenology the flesh and blood, and philosophy is the soul that suffuses them both.

Chapter 3 · The Fourth Month of Meng Xia in the Book of Rites, "Monthly Ordinances": A Cosmic Portrait of Fire Virtue Approaching Its Fullness

I. The Month to Which Xiaoman Belongs: The Fourth Month (the Si Month) and the Virtue of Fire

Xiaoman falls within the fourth lunar month (the solar term Lixia marks the beginning of the fourth month, and Xiaoman marks its midpoint), corresponding to the earthly branch si (巳). Among all pre-Qin texts, the most detailed and systematic description of this fourth-month period is found in the "Monthly Ordinances" (Yueling) chapter of the Book of Rites (Liji)—its content closely parallels the "Record of Meng Xia" (孟夏纪, "First Month of Summer") in the Lüshi Chunqiu (Spring and Autumn Annals of Lü Buwei), and scholars generally hold that the two share a common origin.

The "Monthly Ordinances" sketches a complete cosmological portrait of the Five Phases for the first month of summer (meng xia):

"In the first month of summer... its days are bing and ding; its sovereign is the Flame Emperor; its spirit is Zhurong; its creatures are the feathered; its note is zhi; its number is seven; its flavor is bitter; its smell is scorched; its sacrifice is to the stove, and the lungs are offered first" (孟夏之月……其日丙丁，其帝炎帝，其神祝融，其虫羽，其音徵，其数七，其味苦，其臭焦，其祀灶，祭先肺).

Since Xiaoman and Lixia both belong to the first month of summer and are both correlated with the virtue of Fire, the basic framework of this Five Phases correlation is shared between them. But in interpreting Xiaoman, we should not simply repeat what has already been said of Lixia. Rather, we should focus on those dimensions of this correlative system most closely bound up with "fullness" and with "abundance approaching its utmost"—above all, "its flavor is bitter" and "the flourishing of Fire virtue."

II. "Its Flavor Is Bitter": Why Does Bitterness Belong to Fire, and What Does This Have to Do with Xiaoman$26

In the Five Phases correlations of the Monthly Ordinances, the first month of summer is "bitter" in flavor. The five flavors (sour, bitter, sweet, pungent, salty) correlate with the Five Phases: sour with Wood (spring), bitter with Fire (summer), sweet with Earth (late summer), pungent with Metal (autumn), and salty with Water (winter).

Why does bitterness belong to Fire$27 This question is especially crucial to understanding Xiaoman, because the first of Xiaoman's three pentads is precisely "the bitter herbs flourish" (苦菜秀)—bitter wild greens flourish at this very time.

Our ancestors understood "bitterness belongs to Fire" on several levels. First, from the standpoint of physical sensation: Fire's nature is to blaze upward, its qi is dry and fierce, and at the extreme of dryness, bitterness arises. The scorched, astringent, brow-furrowing sensation of tasting something bitter corresponds naturally to Fire's dry, hot character. Second, from the standpoint of pharmacology: bitter substances are often able to clear heat and purge fire. Bitter herbs, bitter melon, coptis root, and the like are all bitter and capable of relieving summer heat—and this is precisely the exquisite arrangement of the Dao of Heaven: in the first month of summer, when Fire virtue is at its most flourishing and the heat of summer is approaching, Heaven and Earth produce the greatest abundance of bitter things, using the pharmacological nature of "bitterness" to balance the excess of "Fire." What a profound wisdom this is—"regulating qi through flavor"!

Looking deeper still, the association of bitterness with Fire and with summer reveals our ancestors' conception that "taste itself is the Dao of Heaven." In their view, taste was not merely a sensation of the tongue, but a manifestation, within the human body, of the qi of Heaven and Earth. Why is it fitting to eat bitter foods in summer$28 Because in summer the Fire qi is too abundant, and bitterness is needed to draw it inward, to clear and purge it. The traditional practice of "eating bitter in summer" for the cultivation of health is rooted precisely in this Five Phases philosophy of "bitterness belongs to Fire." And that the bitter herbs flourish at Xiaoman is precisely Heaven and Earth using a bitter substance to remind the human world: the virtue of Fire has grown abundant, and one ought to restrain oneself with bitterness.

III. The Flourishing of Fire Virtue and the Threshold of "Approaching but Not Yet at the Extreme"

That the first month of summer is correlated with the virtue of Fire is beyond doubt. But Xiaoman occupies a special position within this month—falling after Lixia and before Mangzhong, it is the transitional stage in which Fire virtue moves from "beginning to flourish" toward "utmost flourishing."

The Monthly Ordinances says of Lixia that "the flourishing virtue lies in Fire" (盛德在火)—the character "flourishing" (盛) here carries considerable weight. By Xiaoman, the flourishing virtue of Fire has advanced a further degree—yet it has still not reached the degree of "yang at its utmost" (阳极) found at the Summer Solstice. At Xiaoman, the virtue of Fire is "approaching flourishing but not yet at its extreme."

This, once again, resonates perfectly with the literal meaning of "Xiaoman." Fire virtue "approaching flourishing but not yet at its extreme" mirrors the wheat kernels "small in fullness but not yet brimming," mirrors the sun's shadow "approaching its shortest but not yet there," mirrors Antares "approaching culmination but not yet there." All these signs across Heaven and Earth point toward one and the same state—"approaching the extreme but not yet at the extreme." Our ancestors named this state "Xiaoman," and deliberately did not let it advance to "great fullness," precisely because they understood well: once Fire virtue reaches "utmost flourishing," this is the turning point at which "yang reaches its extreme and yin is born" (阳极阴生)—the very beginning of decline. To pause at "small fullness" is to pause at that golden moment when Fire virtue is at its most vigorous, yet has not yet triggered the reversal.

IV. The Son of Heaven's Governance in Accordance with the Season: "Continuing to Grow and Rise Higher" in the First Month of Summer, and the "Nurturing" of Xiaoman

The Monthly Ordinances stipulates that in the first month of summer, the Son of Heaven's governmental decrees should be to "continue the growth and let things rise higher, allowing nothing to collapse or fall into ruin, undertaking no earthworks, mobilizing no great multitudes, and felling no great trees" (继长增高，毋有坏堕，毋起土功，毋发大众，毋伐大树).

"To continue the growth and let things rise higher" (继长增高)—to accord with the growing momentum of all things, letting them continue to grow and rise. This is precisely the dominant theme of Heaven and Earth during the Xiaoman season—the wheat is growing, the grain is growing, all things are "continuing to grow and rise higher." And the series of prohibitions—"undertaking no earthworks, mobilizing no great multitudes, felling no great trees, allowing nothing to collapse or fall into ruin"—embodies the requirement of the Dao of Heaven that, at the moment when all things are flourishing and growing, one must not "go against life" or "harm life."

There is a detail here worth savoring: the Monthly Ordinances' governance for the first month of summer is dominated by the themes of "nurturing" (养), "protecting" (护), and "not harming" (不伤)—nurturing and protecting all things now growing, not disturbing them, not damaging them. This wisdom of "nurturing" resonates precisely with the spirit of Xiaoman. Xiaoman is the state in which things are filling but have not yet reached full completion, and precisely at this stage they need to be quietly "nurtured"—nurturing the grain-filling of the wheat kernels, nurturing the joint-forming of the seedlings, nurturing all things on the verge of completion. Should a person act rashly at this time—undertaking earthworks, mobilizing great multitudes, felling great trees—this would be to intrude, at the critical moment when all things are "approaching completion but not yet complete," and would inevitably harm Heaven and Earth's work of generation and transformation.

The Monthly Ordinances also warns of the consequences of governing out of season: "If, in the first month of summer, the ordinances of autumn are carried out, then bitter rains will come repeatedly, and the five grains will fail to flourish..." (孟夏行秋令，则苦雨数来，五谷不滋). To carry out the ordinances of autumn—which belong to "harvesting and killing"—during the first month of summer, when all things are flourishing and growing, would cause the five grains to fail to grow. This confirms, from the opposite direction, the principle of Xiaoman—"nurture, do not harm." At this time, when all things are filling toward fullness, the way of governance lies in cherishing and protecting this "approaching fullness" momentum, and never in applying any act of "harvesting and killing" that would strangle this hard-won abundance before it is complete.

Chapter 4 · No "Great Fullness" After Xiaoman: The Pivotal Mechanism of Chinese Philosophy

I. A Startling Fact: Among the Twenty-Four Solar Terms, "Great Fullness" Alone Is Missing

We now arrive at the very core of this essay.

Look once more, closely, at the full roster of the twenty-four solar terms. Among these twenty-four names, nearly every one containing the character "small" (小) has a corresponding "great" (大) counterpart: Xiaoshu (small heat)—Dashu (great heat); Xiaohan (small cold)—Dahan (great cold); Xiaoxue (small snow)—Daxue (great snow). They come in pairs, "small" preceding "great," recording the process by which summer heat, severe cold, or snowfall accumulates from "small" to "great."

Xiaoman alone is the exception. It stands there in solitude, with no "great fullness" to pair with it. After Xiaoman, the naming of the solar terms suddenly shifts—not to "great fullness," but to Mangzhong (芒种, "Grain in Ear").

Why Mangzhong, and not "great fullness"$29

Mangzhong refers to bearded grains that can be planted or harvested—awned crops such as barley and wheat ripen and are harvested at this time, while awned crops such as rice are sown and transplanted. Note this deeply meaningful turn: at the very moment when the wheat truly reaches "great fullness"—when its kernels are fully ripe and ready for harvest—our ancestors did not name this state of "great fullness" at all. Instead, they immediately turned their attention to the actions of "harvesting" (收, the wheat) and "sowing" (种, the rice).

This turn reveals a profound hidden truth: our ancestors were simply unwilling to linger in the state of "fullness." After Xiaoman, they would rather leap directly into the cycle of "harvest" and "resowing" than establish a "great fullness" to celebrate and savor that summit of completeness. In their wisdom, "fullness" was never meant to be dwelt upon or admired, but to be transcended and transformed—once the wheat is "full," it should be harvested; once harvested, it should be sown again, in an endless cycle that never pauses at the moment of "fullness."

II. Why Is "Great Fullness" Dangerous$30

So wherein, precisely, lies the danger of "great fullness"$31 Why did our ancestors guard against it so warily that they deliberately erased it from the entire system of solar terms$32

The answer lies hidden within the iron law of the waxing and waning of the Dao of Heaven.

The judgment for the top line, shang jiu, of hexagram Qian (乾, the Creative) in the Book of Changes states: "The arrogant dragon has cause for regret" (亢龙有悔). All six lines of hexagram Qian are yang, and by the top line the yang qi has reached its very summit—this is called kang (亢, "arrogant," "overreaching"). Kang means "excessively high," "at the utmost extreme." The dragon has flown to the highest point, with no further road to ascend; what follows can only be a fall—hence "cause for regret." The "Commentary on the Words of the Text" (Wenyan zhuan) explains: "What is meant by kang is this: to know how to advance but not how to retreat, to know how to persist but not how to perish, to know how to gain but not how to lose" (亢之为言也，知进而不知退，知存而不知亡，知得而不知丧). The arrogant dragon has cause for regret precisely because it knows only how to advance and not how to retreat, knows only persistence and not perishing, knows only gain and not loss. It is too full—full to the point where nothing more can be added—and so, when things reach their extreme, they inevitably reverse; when flourishing reaches its utmost, decline must follow.

"Great fullness" is the "arrogant dragon" of the world of solar terms. Were there such a thing as "great fullness," it would be precisely that extreme point which "knows how to advance but not how to retreat, knows how to gain but not how to lose"—it would mean that after completeness there is no further road, only decline. Our ancestors understood this principle well, and so, just before the Dao of Heaven was about to advance toward "great fullness" (the arrogant dragon), they resolutely cut it off with Mangzhong—using the actions of "harvest" and "sowing" to skillfully transform that perilous "summit of completeness" into the starting point of a new cycle.

The line from Chapter 9 of the Laozi—"to hold a vessel and fill it to the brim is not as good as stopping in time"—is precisely the most concentrated warning against the danger of "great fullness." A vessel already at "great fullness" is the most dangerous of all—it is filled to its very limit, and the slightest disturbance will cause it to overflow and topple. "Small fullness" is otherwise—it still has room, still has space, and can still withstand a little disturbance. That our ancestors chose "small fullness" and forsook "great fullness" was precisely a choice of the safety found in "leaving room," over the peril found in "fullness at its very limit."

III. "Great Accomplishment Seems Flawed": Completeness Found Within Imperfection

Chapter 45 of the Laozi contains a profoundly deep line: "Great accomplishment seems flawed, yet its function never fails; great fullness seems empty, yet its function never exhausts" (大成若缺，其用不弊。大盈若冲，其用不穷).

The greatest accomplishment appears to fall somewhat short, yet its usefulness never wears out; the greatest fullness appears empty and insubstantial, yet its usefulness is never exhausted.

This line reads as though it were written expressly as a footnote to "small fullness with no great fullness."

What is meant by "great accomplishment seems flawed"$33 True completeness expresses itself, precisely, as "seeming to still fall a little short." Why$34 Because the moment something presents itself as "utterly complete, without the slightest flaw," it has reached its limit, the very end beyond which no further development is possible—and what follows can only be bi (弊, "wearing out," decline). Whereas "seeming flawed"—retaining a touch of imperfection, a touch of room to spare—allows its function to "never fail," to always retain space for continued growth.

Xiaoman is precisely the solar-term embodiment of "great accomplishment seems flawed." It could well have advanced to "great fullness" (utter completeness), yet it deliberately paused at "small fullness" (a completeness that seems flawed). This "touch of imperfection" is not a deficiency but a great wisdom—it is precisely because this touch of imperfection is retained that all things can have their "function never fail," can continue to move forward, can be sown again after harvest, in an endless cycle.

The same holds for "great fullness seems empty." Chong (冲) means "empty," "hollow." The greatest fullness, it turns out, appears empty instead. This sounds contradictory, yet is in fact profound—one who truly understands "fullness" will keep their own "fullness" in a posture of "emptiness," always retaining space that can be filled again. A person who considers themselves already at "great fullness" can no longer learn, progress, or accommodate anything further; whereas a person who, though full, remains "as if empty," stays forever open to new possibility.

The "small" of Xiaoman is precisely this posture of "seeming empty"—abundant, yet not self-satisfied; substantial, yet leaving room unfilled. That our ancestors let all things pause at "small fullness" is to let them retain the wisdom of "great fullness seems empty"—full, yet not overflowing; brimming, yet still able to accommodate.

IV. "To Accomplish One's Task and Then Withdraw—This Is the Way of Heaven"

Chapter 9 of the Laozi concludes with this line: "To accomplish one's task and then withdraw—this is the Way of Heaven" (功遂身退，天之道也). Once one's achievement is accomplished, one should withdraw and step back—this is the law of Heaven.

Why must one "withdraw" once one's "task is accomplished"$35 Because "accomplishment" is itself a form of "fullness"—the achievement has reached completeness. And according to the principle of the waxing and waning of the Dao of Heaven, "fullness" must inevitably be followed by "deficiency." A wise person, at the very moment their "task is accomplished" (fullness), proactively "withdraws," precisely in order to avoid that "deficiency" which is bound to come. It is like the sun, which must tilt once it reaches noon; rather than wait to be "tilted," it is better to be prepared already at the moment of noon.

The wisdom of "accomplishing one's task and then withdrawing," as embodied in the world of solar terms, is precisely the immediate turn from "Xiaoman" into "Mangzhong." Once the growth of the wheat has "accomplished its task" (Xiaoman, the kernels having filled), the Dao of Heaven immediately "withdraws"—not lingering to show off this fullness, but swiftly turning to the harvest (reaping the wheat). This is the Dao of Heaven's own version of "accomplishing one's task and then withdrawing"—once achievement is attained, there is no lingering attachment to it; instead, one swiftly enters the next cycle.

From this we can see all the more clearly the deep meaning of "small fullness with no great fullness." "Great fullness" would be "accomplishing one's task" without "withdrawing"—it would be a lingering attachment to completeness, a stagnation at the summit. This runs precisely counter to the Way of Heaven, which is to "accomplish one's task and then withdraw." Our ancestors' abolition of "great fullness" was precisely meant to carry through this principle—not letting all things linger in attachment at the summit of "fullness," but letting them "accomplish their task" at "small fullness" and "withdraw" into "Mangzhong," transforming completeness into a new beginning.

V. Blank Space and Room to Spare: The Foundation of Chinese Aesthetics and the Way of Living

The wisdom of "leaving room to spare," embodied in "small fullness with no great fullness," is not merely philosophy—it has also seeped deeply into Chinese aesthetics and the Chinese way of conducting oneself in the world.

Chinese painting prizes "blank space" (留白)—a painting must not be filled entirely; blank space must be left. This blank space is not an absence of content, but the highest form of content; not a deficiency, but an embodiment of "great accomplishment seems flawed." A painting covered entirely in pigment, without the slightest gap, would be like "great fullness"—suffocating, with no lingering resonance. Only by leaving blank space does a painting come "alive," gain room to breathe, and have its "function never fail."

The Chinese way of conducting oneself in the world prizes "leaving room to spare in all things" (凡事留余地)—one's words should not be spoken to their very end, one's actions should not be carried to their extreme, one's feelings should not be spent entirely. Why$36 Because to "speak to the end, act to the extreme, spend entirely" is precisely "great fullness," precisely "the arrogant dragon has cause for regret," precisely to back oneself into a corner from which there is no turning back. To leave a measure of room to spare is like "small fullness"—leaving space for oneself, and for others, to turn, to buffer, to continue.

The Caigentan (Vegetable Root Discourses, though a work of the Ming dynasty, its principles trace back to pre-Qin thought) says: "Flowers are best viewed half-open, wine best drunk to a slight tipsiness—herein lies a great and fine delight" (花看半开，酒饮微醺，此中大有佳趣). Flowers viewed half-open—this is precisely the state of "small fullness"! A flower in full bloom (great fullness) can only wither next; a flower half-open (small fullness) is in the very midst of its most beautiful ascent, its future boundless. Wine drunk to a slight tipsiness—slight tipsiness (small fullness) is the most comfortable state; utter drunkenness (great fullness) is the beginning of misery.

From this we can see that "small fullness with no great fullness" is by no means an isolated calendrical phenomenon, but a core spiritual archetype of Chinese civilization that runs through astronomy, philosophy, aesthetics, and the way of living. That our ancestors quietly sealed this spiritual archetype within the name of a single solar term is a cultural creation of remarkable lightness of touch, and of the most profound significance!

Chapter 5 · The Confucian Perspective: Fullness Invites Loss, Modesty Receives Gain

I. The Timeless Admonition of "Counsels of the Great Yu" in the Book of Documents

Among the pre-Qin classics, the expression of the spirit of "guarding against fullness, prizing modesty" that is most concentrated, and has exerted the most far-reaching influence, is surely that line from "Counsels of the Great Yu" in the Book of Documents: "Fullness invites loss, modesty receives gain—this is the Way of Heaven" (满招损，谦受益，时乃天道).

Self-satisfaction invites loss; modesty receives increase—this is the Way of Heaven.

Note the four characters that conclude the line: "this is the Way of Heaven" (时乃天道). Our ancestors did not treat "fullness invites loss, modesty receives gain" as a mere maxim for conducting oneself in the world, but elevated it to the level of the "Way of Heaven." This means that self-satisfaction inevitably brings loss, and modesty inevitably brings gain, not as a humanly constructed moral convention, but as an objective law of cosmic operation—just like the sun tilting at noon and the moon being eclipsed at its fullest, a heavenly principle that does not bend to human will.

"Fullness invites loss"—these three characters (满招损) are practically the philosophical charter of "small fullness with no great fullness." Why is there no "great fullness"$37 Because "fullness invites loss." The moment "great fullness" is reached, loss follows close behind. Our ancestors' abolition of "great fullness" was precisely meant to spare all things from the fate of "fullness inviting loss," and to keep them instead in the state of "modesty receiving gain."

The "small" of "Xiaoman" is, at its root, a form of "modesty" (谦). It could well have been "full," yet it steps back modestly and takes only "small fullness"; it could well have occupied the very summit of fullness, yet it steps back modestly, leaving room to rise further. This "smallness" is "modesty"; and this "modesty" is what enables "gain"—what enables continued growth, continued filling, and the arrival of a true harvest.

II. Confucius Beholding the "Vessel That Tilts When Seated in Honor": "How Could There Be a Thing That, Once Full, Does Not Overturn$38"

The "Yòu Zuò" (宥坐) chapter of the Xunzi records an extraordinarily vivid and profound story, one that best embodies the Confucian attitude toward "fullness":

"Confucius, visiting the ancestral temple of Duke Huan of Lu, saw a tilting vessel there. He asked the temple keeper: 'What sort of vessel is this$39' The keeper replied: 'This, I believe, is a vessel for admonishing those who sit in honor.' Confucius said: 'I have heard that such a vessel, when empty, tilts; when filled to the middle, stands upright; and when filled to the brim, overturns.' Confucius turned to his disciples and said: 'Pour water into it.' The disciples ladled water and poured it in. Filled to the middle, it stood upright; filled to the brim, it overturned; empty, it tilted once more. Confucius sighed deeply and said: 'Ah! How could there be a thing that, once full, does not overturn!'" (孔子观于鲁桓公之庙，有欹器焉。孔子问于守庙者曰：「此为何器？」守庙者曰：「此盖为宥坐之器。」孔子曰：「吾闻宥坐之器者，虚则欹，中则正，满则覆。」孔子顾谓弟子曰：「注水焉。」弟子挹水而注之。中而正，满而覆，虚而欹。孔子喟然而叹曰：「吁！恶有满而不覆者哉！」)

In the ancestral temple of Duke Huan of Lu, Confucius saw a vessel that tilted at an angle. He asked the temple keeper what it was, and the keeper explained that it was a "vessel for admonishing those who sit in honor"—an object placed to the right of one's seat as a warning to oneself. Confucius said: "I have heard that this kind of vessel tilts when empty, stands upright when filled halfway, and overturns when filled to the brim." He then had his disciples pour in water. And indeed—filled halfway, the vessel stood upright; filled to the brim, it overturned; and once empty again, it tilted once more. Confucius sighed deeply: "Ah! How could there be a thing that, once full, does not overturn!"

"How could there be a thing that, once full, does not overturn$40" (恶有满而不覆者哉)—this is the most sorrowful, and also the most profound, lament that Confucius uttered in the face of "fullness."

This "vessel for admonishing those who sit in honor" (also known as the qiqi or "tilting vessel") is practically the ideal teaching instrument for the philosophy of "small fullness." It demonstrates, in the most intuitive way, the principle of the Dao of Heaven's waxing and waning: "empty, it tilts" (虚则欹, emptiness brings instability), "filled to the middle, it stands upright" (中则正, the mean brings uprightness, the optimal state), "filled to the brim, it overturns" (满则覆, fullness brings overturning, calamity).

Consider that "filled to the middle, it stands upright"—filled halfway (precisely like "small fullness"), the vessel is at its most upright and stable. This is precisely the state of "Xiaoman"! And "filled to the brim, it overturns"—filled completely (precisely like "great fullness"), the vessel immediately topples. This is precisely the fate of "great fullness"!

Our ancestors' abolition of "great fullness" and preservation of "small fullness" is one and the same wisdom as Confucius's lament, on beholding the tilting vessel, that "fullness brings overturning." A vessel that is full overturns; a solar term that is "full" is perilous—hence it is better to take the "mean" (small fullness) than "fullness" (great fullness). The principle that Confucius taught his disciples through a single vessel is the same principle our ancestors taught an entire civilization through the naming of a single solar term.

III. The Way of the Mean: The "Just Right"-ness of "Small Fullness"

The Confucian thought of "guarding against fullness, prizing modesty" ultimately crystallizes into the Doctrine of the Mean (中庸).

Confucius said: "As a virtue, the Mean is the very highest! It is rare indeed that the common people have long possessed it" (中庸之为德也，其至矣乎！民鲜久矣; Analects, "Yong Ye"). As a virtue, the Mean is supreme! Yet it is a pity that the common people have so rarely been able to attain it, and for so long.

What is "the Mean"$41 The "Doctrine of the Mean" (Zhongyong) chapter of the Book of Rites states: "Before joy, anger, sorrow, and delight have arisen, this is called equilibrium (zhong); when they arise and all attain due measure, this is called harmony (he)" (喜怒哀乐之未发，谓之中；发而皆中节，谓之和). It also says: "Grasping the two extremes, and applying the mean between them to the people" (执其两端，用其中于民). The Mean is not mediocrity, nor is it mere compromise, but "just the right amount"—neither excessive nor deficient.

And "Xiaoman" is precisely the perfect embodiment of "the Mean" within the solar terms. It has passed beyond the stage of Lixia (deficiency), yet has not reached the extreme of the Summer Solstice (excess); it is full (not "deficient"), yet not overflowing (not "excessive"). It pauses precisely at that "just right" point of "the mean"—precisely the state of "filled to the middle, it stands upright" that Confucius observed before the tilting vessel.

Why is "the mean" so precious$42 Because "the mean" is the only stable state. "Empty, it tilts" (deficiency, instability), "filled to the brim, it overturns" (excess, overturning)—only "filled to the middle, it stands upright" (just right, uprightness) endures. All things, in every affair, can persist, remain stable, and have their "function never fail" only when situated in the state of "the mean." Xiaoman, as the embodiment of "the mean," tells us: the best state is not the fullest, but the just-right; not the summit, but the moderate mean.

IV. Hexagram Qian (Modesty) in the Book of Changes: The Way of Heaven Diminishes Fullness and Augments Modesty

Among the sixty-four hexagrams of the Book of Changes, revered by the Confucian school, one hexagram is devoted entirely to "modesty" (谦)—this is hexagram Qian (謙, Di Shan Qian, "Earth over Mountain: Modesty"). Among the sixty-four hexagrams, Qian is the only one in which "all six lines are auspicious" (with not a single line bearing misfortune or blame). This fact alone is deeply meaningful—in the world of the Book of Changes, "modesty" alone brings a hundred benefits and no harm whatsoever.

The "Commentary on the Judgment" of hexagram Qian states: "The Way of Heaven diminishes fullness and augments modesty; the Way of Earth alters fullness and directs it toward modesty; ghosts and spirits harm fullness and bless modesty; the Way of humanity detests fullness and delights in modesty. Modesty, in the honored, shines forth; in the lowly, it cannot be overstepped—this is the end that the noble person brings to fulfillment" (天道亏盈而益谦，地道变盈而流谦，鬼神害盈而福谦，人道恶盈而好谦。谦尊而光，卑而不可逾，君子之终也).

The Way of Heaven diminishes what is full and augments what is modest; the Way of Earth topples and transforms what is full and lets it flow toward what is modest; ghosts and spirits bring harm to what is full and bestow blessing upon what is modest; the Way of humanity detests what is full and delights in what is modest. Modesty makes the honored shine yet brighter, and makes the lowly beyond being overstepped—this is the way by which the noble person brings good beginnings to good endings.

This passage carries the Dao of Heaven's principle of "guarding against fullness, prizing modesty" to its very extreme—Heaven, Earth, the spirits, and humanity, every force in the cosmos without exception, "detests fullness and delights in modesty," "harms fullness and blesses modesty." In a cosmos so universally opposed to "fullness," what room could there possibly be for "great fullness" to exist$43 It would inevitably be "diminished" by Heaven, "toppled" by Earth, "harmed" by the spirits, and "detested" by humanity. Our ancestors' abolition of "great fullness" was precisely an accordance with this fundamental heavenly principle by which "all four Ways detest fullness."

And that all six lines of hexagram Qian are auspicious positively demonstrates the value of the "smallness" (modesty, restraint) in "Xiaoman." The "small" of "Xiaoman" is precisely "modesty"; only through this "modesty" can one "receive gain," can one have "all six lines auspicious," and can one advance in safety, favored universally by Heaven, Earth, the spirits, and humanity. That our ancestors let all things pause at "small fullness" (modesty), rather than advance to "great fullness" (fullness), was precisely their choosing, for all things, that path of modest restraint on which "all six lines are auspicious."

V. The Noble Person "Fills Every Hollow Before Advancing": Substantial Growth Without Impetuous Haste

Master Meng (Mencius) has a passage that expresses, with utter clarity, the Confucian spirit of "valuing process, guarding against empty fullness":

"The water from a living spring gushes forth ceaselessly, flowing on day and night, filling every hollow along its course before advancing further, until it reaches the four seas. Such is the nature of water that has a source—this is what it takes hold of. But if it has no source, then when the rains gather in the seventh and eighth months, all the ditches and channels are filled to the brim; yet when the rain stops, their drying up can be awaited standing on one's feet" (原泉混混，不舍昼夜，盈科而后进，放乎四海。有本者如是，是之取尔。苟为无本，七八月之间雨集，沟浍皆盈；其涸也，可立而待也; Mencius, "Li Lou II").

The living water from its source comes rushing forth, never resting day or night, filling each low-lying hollow before pressing onward, until at last it reaches the four seas. Water with a true source is like this. But if it has no source, then when the rains gather during the seventh and eighth months, the ditches and channels, great and small, all fill up; yet once the rain stops, they dry up in no time at all—one need only stand and wait.

How profound are these five characters: "filling every hollow before advancing" (盈科而后进)! True growth is like living water—first filling every low place completely, and only then advancing further. This is a solid, unhurried, step-by-step process of "filling." The floodwater that fills "all the ditches and channels," by contrast, seems to become "full" all at once (great fullness), yet in truth has no foundation, and dries up in an instant.

This metaphor of Master Meng's illuminates precisely the distinction between the "substance" of "small fullness" and the "emptiness" of "great fullness." "Small fullness" is the true, substantial filling of "filling every hollow before advancing"—the wheat kernels fill with grain, solidly, day by day, with deep roots and a vast future ahead. False "great fullness," by contrast, is like the floodwater that fills "all the ditches and channels"—seemingly complete, yet in truth insubstantial, its decline from utmost flourishing arriving in the blink of an eye. Our ancestors' esteem for the solid, gradual filling embodied in "small fullness," and their wariness of the insubstantial, quickly-spent completeness embodied in "great fullness," is one and the same wisdom as Master Meng's distinction between "that which has a source" and "that which has none."

Chapter 6 · The Daoist Perspective: Knowing Contentment Brings No Disgrace, Knowing When to Stop Brings No Danger

I. The Most High (Laozi) on "Fullness": One Who Preserves This Dao Does Not Desire to Be Full

If the Confucian school elucidates "guarding against fullness" from the standpoint of "the virtue of modesty," the Daoist school pushes the wisdom of "guarding against fullness" toward a yet more transcendent realm, from the standpoint of "contentment" and "preserving emptiness."

Chapter 15 of the Laozi states: "One who preserves this Dao does not desire to be full. It is precisely because of not being full that one can discard the old and continually achieve renewal" (保此道者，不欲盈。夫唯不盈，故能蔽而新成).

One who holds fast to this "Dao" does not pursue fullness. Precisely because of not being full, one is able to shed the old and constantly bring about new achievement.

"Does not desire to be full" (不欲盈)—these three characters are the Daoist school's fundamental attitude toward "fullness." Note that the Most High does not say "cannot be full," but rather "does not desire to be full"—it is not that fullness is unattainable, but that one proactively and consciously refrains from pursuing it. This is a state of the highest order—one who could well be "full," yet chooses "not-fullness"; one who could well attain "great fullness," yet is at peace with "small fullness."

"It is precisely because of not being full that one can discard the old and continually achieve renewal"—precisely because of not being full, one is able to maintain a state of "the worn" (蔽, the old, the empty, the incomplete), and thereby gain the capacity for "continual achievement" (constant renewal, constant accomplishment). This is the very same principle as the earlier passage, "great accomplishment seems flawed, yet its function never fails"—retaining a touch of incompleteness, in fact, grants one the vitality of perpetual renewal.

"Xiaoman" is precisely the cosmic practice of "not desiring to be full." The qi of Heaven and Earth could well fill to "great fullness," yet it "does not desire to be full," and remains at peace with "small fullness"—precisely because of this, all things are able to "discard the old and achieve renewal," able to continue, after Xiaoman, toward Mangzhong, toward harvest, toward the next round of sowing, in ceaseless renewal. Were the qi of Heaven and Earth truly to fill to "great fullness," it would have reached its end, with no more room left for "renewal."

II. "Knowing Contentment Brings No Disgrace, Knowing When to Stop Brings No Danger, and Thus One May Long Endure"

Chapter 44 of the Laozi is the most concentrated expression of the Daoist thought of "knowing contentment, knowing when to stop":

"Which is closer to oneself—reputation or one's own body$1 Which is more valuable—one's own body or material goods$2 Which is more harmful—gain or loss$3 Therefore, excessive attachment inevitably brings great expenditure, and excessive hoarding inevitably brings heavy loss. Knowing contentment brings no disgrace; knowing when to stop brings no danger. Thus one may long endure" (名与身孰亲？身与货孰多？得与亡孰病？是故甚爱必大费，多藏必厚亡。知足不辱，知止不殆，可以长久).

Which is dearer, reputation or one's own life$4 Which is more precious, one's own life or material wealth$5 Which is more harmful, gaining or losing$6 Therefore, excessive fondness inevitably brings great cost, and excessive hoarding inevitably brings grievous loss. To know contentment is to avoid disgrace; to know when to stop is to avoid danger—and only thus can one endure long.

"Knowing contentment brings no disgrace, knowing when to stop brings no danger" (知足不辱，知止不殆)—these eight characters are the Daoist school's highest endorsement of the philosophy of "Xiaoman."

"Knowing contentment" (知足)—being content with "small fullness," not coveting "great fullness." "Knowing when to stop" (知止)—stopping where one ought to stop, pausing at "small fullness," advancing no further toward "great fullness." A person (or a cosmos) who "knows contentment and knows when to stop" will be content with the state of "a small attainment of fullness," rather than greedily pursuing that perilous "great fullness."

Why does "knowing when to stop" bring "no danger"$7 Because failing to know when to stop, and pressing relentlessly forward, would carry one past the stable state of "small fullness" and hurl one against the perilous cliff of "great fullness"—"fullness brings overturning," and this is precisely "danger" (殆). Only by "knowing when to stop" at "small fullness" can one achieve "no danger," can one "long endure."

The phrase "excessive hoarding inevitably brings heavy loss" strikes especially close to the flaw of "great fullness." "Great fullness" is precisely "excessive hoarding"—amassing everything to its very limit. And "excessive hoarding inevitably brings heavy loss"—the more one accumulates, the more grievous the loss when it comes. That our ancestors did not let all things reach "great fullness" (excessive hoarding) was precisely to spare them from "heavy loss." Pausing at "small fullness" (moderation) allows one to "long endure."

III. "To Hold a Vessel and Fill It to the Brim Is Not as Good as Stopping in Time": Further Reflections on the Most High's Admonition Against Fullness

We have already cited, earlier, Chapter 9 of the Laozi: "to hold a vessel and fill it to the brim is not as good as stopping in time." This deserves further elaboration here, for this line reads as though it were written expressly for "Xiaoman."

"To hold a vessel and fill it to the brim" (持而盈之)—holding a vessel, and still wishing to add more to it, to make it fuller and fuller still. This is a posture of greed, an obsession with "fullness." "Is not as good as stopping in time" (不如其已)—it is better to stop right there.

This line forms a remarkable resonance with the "vessel for admonishing those who sit in honor" that Confucius observed. Confucianism and Daoism—one using the "tilting vessel" (fullness brings overturning), the other using "holding to fullness" (fullness brings overflow)—arrive, from different angles, at the very same truth: fullness at its limit must lead to overturning or overflowing, and so the wise course is "filled to the middle, it stands upright" (Confucianism), or "not as good as stopping in time" (Daoism)—both advocate pausing "before fullness," pausing at "small fullness."

The Daoist school carries this wisdom to an even more thoroughgoing conclusion. In the Daoist view, the operation of the entire cosmos is a cycle of "emptiness—fullness—emptiness," and the "Dao" stands forever on the side of "emptiness." Chapter 4 of the Laozi states: "The Dao is empty, yet in use it is never filled" (道冲，而用之或不盈). The Dao is empty and void, yet its function is never exhausted by fullness. Chapter 5 states: "Empty, yet it never collapses; the more it moves, the more it yields" (虚而不屈，动而愈出). The space between Heaven and Earth is empty, yet never exhausted; the more it is set in motion, the more it produces. The Dao is "ceaselessly generative" precisely because it is "empty" and "not full"—it forever preserves the space to produce yet more.

"Xiaoman" is precisely the state that accords with the "Dao"—it is "not full," and so its "function is never exhausted"; it is "empty" (relative to great fullness), and so "the more it moves, the more it yields." "Great fullness," by contrast, runs counter to the "Dao"—it is "full," and so its "function" is on the verge of "exhaustion"; it is "solid," and so its "motion" is on the verge of running "dry." Our ancestors' choice of "small fullness" was, at its root, a choice of that state which accords with the "Dao," ceaselessly generative and never exhausted.

IV. Master Zhuang on "The Empty Chamber Gives Birth to Brightness" and "The Usefulness of the Useless"

Master Zhuang (Zhuangzi) carried the Daoist wisdom of "preserving emptiness, guarding against fullness" to a yet more ethereal realm.

The "In the World of Men" (Renjian Shi) chapter of the Zhuangzi states: "Behold that vacant space—the empty chamber gives birth to brightness, and good fortune comes to rest in stillness" (瞻彼阕者，虚室生白，吉祥止止). Behold that vacant place—within the empty chamber, brightness is born instead, and good fortune comes to rest in this place of emptiness and stillness.

"The empty chamber gives birth to brightness" (虚室生白)—an empty room, instead, becomes filled with light. This is an image of great beauty and great depth. A room piled full of clutter (great fullness) is dark, cramped, and utterly devoid of vitality; only an empty room (emptiness, smallness) can let light stream in, can "give birth to brightness."

The human heart is the same. A heart filled to the brim with desires, preconceptions, and self-satisfaction (great fullness) cannot possibly receive new wisdom, cannot possibly "give birth to brightness"; only by preserving emptiness (small fullness, seeming hollowness) can one let the brightness of the Dao stream in.

Viewed in this light, the "small" of "Xiaoman" appears all the more wise. "Xiaoman" is the "empty chamber"—it preserves space, and so can "give birth to brightness," can receive, can renew itself. "Great fullness," by contrast, is the "filled chamber"—it has been filled up, and so is dark, cramped, and unable to "give birth to brightness."

Master Zhuang also discourses on "the usefulness of the useless." In the "In the World of Men" chapter of the Zhuangzi, the sacred oak tree at the village shrine, deemed "useless" by the craftsman, is precisely because of its "uselessness" that it manages to preserve its natural span of years and grow into a towering tree. Master Zhuang draws out the point: "All people know the usefulness of the useful, but none know the usefulness of the useless" (人皆知有用之用，而莫知无用之用也). Everyone knows the use of what is "useful," yet no one knows the use of what is "useless."

This wisdom of "the usefulness of the useless" likewise corroborates the principle of "Xiaoman." "Great fullness" pushes everything to the very limit of "use" (the utmost of usefulness), with the result that it is swiftly exhausted and declines toward ruin; "small fullness" retains a portion "unused," "not spent to the end" (a margin approaching "uselessness"), and is thereby able to endure long. To retain a measure of incompleteness, a measure left unspent, may seem "useless," yet it is in truth the greatest "usefulness" of all—it is the fundamental guarantee that "its function never fails."

Chapter 7 · Hexagram Qian in the Book of Changes: The Six Yang Lines of Pure Yang and "The Arrogant Dragon Has Cause for Regret"

I. Hexagram Qian in the Fourth Month: The Threshold of Pure Yang at Its Extreme

Xiaoman falls within the fourth lunar month (the si month), and in the system of the twelve sovereign hexagrams (shier xiaoxi gua), the fourth month corresponds to hexagram Qian (乾, all six lines yang). This is shared with Lixia, both belonging to the fourth month. But in interpreting the Qian hexagram in relation to Xiaoman, we must place our emphasis on that distinctive warning within hexagram Qian most closely bound up with "fullness"—"the arrogant dragon has cause for regret."

The twelve sovereign hexagrams correspond, one hexagram to each of the twelve months, displaying the full course of yin and yang's waxing and waning across the year: the eleventh month, hexagram Fu (復, Return, one yang line born); the twelfth month, hexagram Lin (臨, Approach, two yang lines growing); the first month, hexagram Tai (泰, Peace, three yang lines, "the small departs and the great arrives"); the second month, hexagram Dazhuang (大壯, Great Strength, four yang lines flourishing); the third month, hexagram Guai (夬, Resolution, five yang lines dispelling yin); the fourth month, hexagram Qian (乾, six yang lines, pure yang)—after which yin qi begins to sprout—the fifth month, hexagram Gou (姤, Encounter, one yin line born); the sixth month, hexagram Dun (遯, Retreat, two yin lines growing); the seventh month, hexagram Pi (否, Stagnation); the eighth month, hexagram Guan (觀, Contemplation); the ninth month, hexagram Bo (剝, Splitting Apart); and the tenth month, hexagram Kun (坤, the Receptive, six yin lines, pure yin).

In the fourth month, hexagram Qian, with all six lines yang, marks the moment within the year when yang qi is purest, most flourishing, most full. This is the "utmost flourishing" of yang qi, the "great fullness" of the yang qi of Heaven and Earth.

But note a startling fact: precisely after this hexagram Qian of "six yang lines, pure yang," this "great fullness" of yang qi, the very next month, the fifth month, is hexagram Gou (姤)—"one yin line born beneath." The instant yang qi reaches "great fullness" (Qian), yin qi immediately sprouts from below (Gou). This is the most naked demonstration of the Dao of Heaven's principle that "when things reach their extreme, they inevitably reverse"—the moment fullness reaches its utmost point (Qian, six yang lines), decline (yin born, Gou) begins at once.

Xiaoman falls within hexagram Qian, precisely at that subtle moment when yang qi is "approaching fullness" but has not yet triggered the reversal of "yin being born." It enjoys the grandeur of yang qi within hexagram Qian, yet, through the restraint of "small fullness," avoids the perilous cliff of "Qian at its extreme giving birth to Gou." What an exquisite wisdom of Heaven and humanity this is—dwelling within pure-yang Qian, yet holding fast to "small fullness," refusing to let itself truly reach that turning point of "six yang lines at great fullness, one yin line about to be born."

II. "The Arrogant Dragon Has Cause for Regret": Why Does the Extreme of Yang Turn to Misfortune$8

The six lines of hexagram Qian, from bottom to top, depict the entire course of yang qi (the dragon), from hidden to flying, from flying to overreaching: the first line (chu jiu), "the hidden dragon, do not act"; the second line (jiu er), "the dragon appears in the field"; the third line (jiu san), "the noble person is diligent and cautious all day"; the fourth line (jiu si), "wavering, as if leaping over an abyss"; the fifth line (jiu wu), "the flying dragon is in the heavens"; and the top line (shang jiu), "the arrogant dragon has cause for regret."

Consider this trajectory from "hidden" to "flying" to "overreaching." The fifth line, "the flying dragon is in the heavens," is the most glorious and ideal state of yang qi—the dragon soars through the sky, its ambitions realized on a grand scale, precisely the summit of a life or a career. Yet a mere single line later, at the top line, we arrive at "the arrogant dragon has cause for regret"—the dragon has flown too high, to the point of "overreaching" (亢), and so "has cause for regret."

Between "the flying dragon is in the heavens" (the fifth line) and "the arrogant dragon has cause for regret" (the top line) lies but a single line, and yet the gulf between fortune and misfortune, between flourishing and decline, is as wide as Heaven and Earth. The fifth line is the optimal state, like "small fullness"—grand and flourishing, but not yet at the extreme; the top line is the perilous extreme, like "great fullness"—flourishing to the point where nothing more can be added, so that things reach their extreme and inevitably reverse.

The "Commentary on the Words of the Text" offers a profoundly deep explanation of the top line: "What is meant by 'the arrogant dragon has cause for regret'$9 The Master said: 'Honored, yet without position; exalted, yet without a following of the people; worthy men occupy positions below and give no assistance—hence, to act is to have cause for regret'" ('亢龙有悔'，何谓也？子曰：'贵而无位，高而无民，贤人在下位而无辅，是以动而有悔也。'). The dragon has flown too high, and so has become detached from its foundation—honored, yet without any real position; exalted, yet without the support of the people; the worthy are all below, out of reach, unable to give assistance—and so any action taken brings regret.

This passage reveals the fundamental reason for the misfortune of "overreaching" (great fullness): detachment from one's foundation. Flying too high means becoming detached from the earth, from the people, from every foundation that supports one, and so one becomes like "water without a source, a tree without roots," inevitably destined to collapse. How closely this resonates with Master Meng's metaphor of "water without a source" (the ditches and channels fill and then dry up standing)!

And the preciousness of "small fullness" lies precisely in this: it does not "overreach," does not become detached from its foundation. It pauses at the stable state just before "the flying dragon is in the heavens," its foundation deep, the people in support, the worthy giving assistance—and so it "acts without regret," able to endure long. Our ancestors' abolition of "great fullness" (the arrogant dragon) was precisely to spare all things from "acting with regret," and to keep them instead in the state of "small fullness" (the flying dragon approaching but not yet arrived), which "acts without regret."

III. "The Application of Nine": Seeing a Flock of Dragons Without a Head Is Auspicious

Beyond its six lines, hexagram Qian has one further, unique line statement—"The application of nine: seeing a flock of dragons without a head is auspicious" (用九：见群龙无首，吉).

"A flock of dragons without a head" (群龙无首)—a flock of dragons, yet with no single dragon that leads, that stands foremost. To ordinary people this might seem like disorder, and yet the Book of Changes declares it "auspicious." Why$10

The "Commentary on the Words of the Text" explains: "The application of nine in Qian, the Origin, brings order to all under Heaven" (乾元用九，天下治也). It also says: "The application of nine in Qian, the Origin, thereby reveals the pattern of Heaven" (乾元用九，乃见天则). What the "application of nine" embodies is precisely the law of Heaven.

The reason "a flock of dragons without a head" is auspicious lies precisely in this "headlessness"—no single dragon contends to stand foremost, to fly to the very highest, to "overreach." Every dragon steps back modestly, none is willing to occupy the position of "head" (the extreme, great fullness), and so the entire flock of dragons avoids the fate of "the arrogant dragon has cause for regret," and thereby achieves "order under Heaven" and "auspiciousness."

This wisdom of "a flock of dragons without a head" is, in fact, another expression of "small fullness with no great fullness." "Headlessness" is "no great fullness"—there is no extreme point that all contend to reach, to complete. Having demonstrated the peril of "the arrogant dragon has cause for regret," hexagram Qian immediately points, through the "application of nine" and "a flock of dragons without a head," to the way of avoiding misfortune—not contending for the foremost position, not coveting fullness, dwelling in modest restraint—only thus can one attain "auspiciousness." Our ancestors' abolition of "great fullness," letting all things pause at "small fullness" in the manner of "a flock of dragons without a head," deeply grasps the intent of hexagram Qian's "application of nine."

IV. Hexagram Qian and "Xiaoman": Flourishing in Yang, Yet Knowing to Guard Against Excess

Surveying hexagram Qian as a whole, we may draw a profound conclusion: although Qian is the most "vigorous," the most "yang-flourishing" of the sixty-four hexagrams, its highest wisdom lies precisely in "knowing to guard against excess" at the very moment of yang's flourishing—knowing "the arrogant dragon has cause for regret," knowing "a flock of dragons without a head," knowing that after "the flying dragon is in the heavens," one must advance no further.

The "Commentary on the Images" of hexagram Qian in the Book of Changes states: "Heaven's motion is vigorous; the noble person, in accordance with this, ceaselessly strengthens himself" (天行健，君子以自强不息). This is the aspect of striving and advancement that hexagram Qian offers to humanity. But hexagram Qian, at the same time, warns humanity through "the arrogant dragon has cause for regret": ceaseless self-strengthening is indeed precious, but one must never "overreach"—must never grow so strong as to become detached from one's foundation, so full as to admit nothing more. True "ceaseless self-strengthening" is like "Xiaoman"—striving vigorously upward (yang flourishing), while also leaving room to spare (not overreaching), maintaining a constant vigilance against "fullness" even in the midst of abundance.

This is the deepest correspondence between hexagram Qian and "Xiaoman"—flourishing in yang, yet knowing to guard against excess; abundant, yet wary of overreaching. Xiaoman dwells within pure-yang Qian, enjoying the grandeur of Heaven and Earth's yang qi, yet holds itself in restraint through the character "small," ever warning itself with "the arrogant dragon has cause for regret," forever pausing on that wisest of lines between the glory of "the flying dragon is in the heavens" and the perilous cliff of "the arrogant dragon has cause for regret."

Chapter 8 · The First Pentad: The Bitter Herbs Flourish—Fire Virtue and Poetry Within Bitterness

I. "The Bitter Herbs Flourish": The Phenological Reality of the First Pentad

The "Treatise on Seasonal Training" (Shixun Jie) in the Yi Zhoushu (Lost Book of Zhou), together with the Monthly Ordinances of successive dynasties, records the three pentads of Xiaoman as follows: "On the day of Xiaoman, the bitter herbs flourish; five days later, the mi grass dies; five days after that, wheat's autumn arrives (in some versions, 'the small heat arrives,' though 'wheat's autumn arrives' is regarded as correct)" (小满之日，苦菜秀；又五日，靡草死；又五日，麦秋至).

The first pentad is "the bitter herbs flourish" (苦菜秀). The Shuowen glosses the character xiu (秀) as a taboo character reserved for the emperor above (avoiding the personal name of Emperor Guangwu of Han, Liu Xiu, and so Xu Shen did not state its meaning explicitly), yet its original meaning, according to most classical glosses, refers to plants and trees "flowering and bearing fruit." Confucius, in the Analects, "Zi Han," says: "There are cases, surely, of a shoot that grows but never flowers (xiu)! And there are cases, surely, of one that flowers (xiu) but never bears fruit!" (苗而不秀者有矣夫！秀而不实者有矣夫！)—there are cases where a seedling grows but never puts forth its ear (xiu), and cases where it puts forth its ear (xiu) but never bears grain. From this we can see that xiu refers to a plant putting forth its ear, flowering, and flourishing.

"The bitter herbs flourish" means that, by Xiaoman, the bitter herb—a kind of wild green—grows most luxuriantly, its stalks shooting up and bursting into flower one after another. The bitter herb is a bitter-tasting wild plant (called tu 荼 or ku mai 苦荬 in ancient texts), which grows most abundantly in early summer.

Why did our ancestors place "the bitter herbs flourish" as the very first pentad of Xiaoman$11 This was by no means an arbitrary choice. At Xiaoman, a season when Fire virtue is gradually flourishing and the heat of summer is approaching, the very first thing to flourish between Heaven and Earth is precisely this bitter-tasting wild plant—and within this lies a profound principle governing both the Dao of Heaven and human affairs.

II. The Bitter Herb and Fire Virtue: The Dao of Heaven's Exquisite Arrangement of "Bitterness Answering Fire"

We have already noted, in discussing "its flavor is bitter," that bitterness belongs to Fire and correlates with summer within the Five Phases. That "the bitter herbs flourish" occurs precisely at Xiaoman, when Fire virtue is gradually flourishing, is by no means coincidental, but an exquisite arrangement of the Dao of Heaven—"bitterness answering Fire."

Why, at the moment Fire qi is about to flourish, do Heaven and Earth choose precisely this moment to let bitter things flourish$12 Here lies a profound principle of both health cultivation and the Dao of Heaven—bitterness can clear Fire. The bitter herb is cool in nature and bitter in flavor, precisely a natural remedy for relieving summer heat and dispelling the toxin of Fire. Just as Fire virtue is about to flourish, and the searing heat of summer approaches, Heaven and Earth produce, in advance, an abundance of the bitter herb—as though preparing an "antidote" for the scorching heat soon to come. This is a form of compassion and consideration that the Dao of Heaven extends to all things (and especially to humanity)—flourishing Fire is approaching, and the means to clear it have already been prepared.

The traditional practice of "eating bitter in summer" for health cultivation has its roots precisely here. The Book of Songs (Shijing), in "Gu Feng" from the "Airs of Bei," contains the line "Who says the bitter herb is bitter$13 It is as sweet as shepherd's purse" (谁谓荼苦？其甘如荠)—tu (荼) here referring to the bitter herb. In the material scarcity of high antiquity, the bitter herb was an important wild vegetable for relieving famine during the "lean season" (Xiaoman falls precisely in that lean season when the wheat is not yet ripe and the old grain is nearly exhausted). That Heaven and Earth produce the bitter herb precisely when people are most short of grain, and produce Fire-clearing plants precisely when Fire is most flourishing—this pentad of "the bitter herbs flourish" is both a phenological fact and an act of compassion, on the part of Heaven and Earth, toward all living beings.

III. The Philosophy of "Bitterness": Enduring the Bitterest of the Bitter

"The bitter herbs flourish," as the first pentad of Xiaoman, also thrusts before us the character "bitter" (苦), inviting deep reflection on the profound significance of "bitterness" within Chinese culture.

Note a deeply meaningful arrangement: at the very moment when all things are attaining "a small fullness," a season brimming with hope and joy, the first pentad is, of all things, "bitter"—the bitter herbs flourish. What a profound reminder this is! It is as though saying: abundance (fullness) and bitterness have always been born together; the closer one draws to the joy of harvest, the more fully one must first taste the bitterness of the grain-filling process.

This is precisely the archetype of the Chinese wisdom that "bitterness ends and sweetness comes," that "only by enduring the bitterest of the bitter can one rise above other people." At Xiaoman, the wheat is filling with grain—this is the wheat's most "laborious" stage, as it exerts all its strength to send nourishment into the kernels. The farmer, too, is at their most laborious at this time—tending the nearly ripe wheat, while also preparing for the imminent "three summer tasks" (summer harvest, summer sowing, summer field management) that will follow close behind. That "the bitter herbs flourish" falls precisely at this moment seems to be Heaven and Earth's own corroboration and illumination of this "bitterness"—before fullness, there must first be bitterness; before sweetness, one must first taste what is bitter.

Master Meng's celebrated and timeless passage resonates perfectly with "the bitter herbs flourish": "Therefore, when Heaven is about to confer a great responsibility on a person, it will always first embitter their heart and will, labor their sinews and bones, starve their body and flesh, impoverish their person, and confound their undertakings—thereby stirring their heart, hardening their nature, and increasing their capacity where they were formerly incapable" (故天将降大任于是人也，必先苦其心志，劳其筋骨，饿其体肤，空乏其身，行拂乱其所为，所以动心忍性，曾益其所不能; Mencius, "Gaozi II"). When Heaven is about to confer a great task upon a person, it must first let them undergo all manner of hardship—"embittering their heart and will." This "bitterness" is not punishment, but tempering, the necessary path toward "increasing their capacity where they were formerly incapable."

The bitter herbs flourishing at Xiaoman is precisely Heaven and Earth's own version of "embittering the heart and will"—just before all things reach "great completion" (harvest), they are first tempered and ground down by "bitterness." Only through this tempering of "bitterness" can that "small fullness" ultimately advance to a true and full harvest.

IV. The Image of the Bitter Herb in the Book of Songs

The bitter herb (tu, or ku) is an image that recurs again and again throughout the Book of Songs, carrying within it the rich emotional life of our ancestors.

The Book of Songs, in "Cai Ling" from the "Airs of Tang," contains the line "Gathering bitter herbs, gathering bitter herbs, at the foot of Mount Shouyang" (采苦采苦，首阳之下)—gathering bitter herbs at the foot of Mount Shouyang. The Book of Songs, in "Qi Yue" from the "Airs of Bin," contains the line "We gather the bitter herb and cut the foul-smelling tree for firewood, to feed us farmers" (采荼薪樗，食我农夫)—gathering the bitter herb and felling the foul-smelling chu tree for fuel, in order to sustain us farmers. These lines record, plainly and simply, the actual place the bitter herb held in the lives of our ancestors—an ordinary wild vegetable on the farmer's table, sustenance during hard times.

The line from "Gu Feng" in the "Airs of Bei," "Who says the bitter herb is bitter$14 It is as sweet as shepherd's purse," elevates the image of "bitterness" to a philosophical height. A woman abandoned by her husband, lamenting her own sorrow and bitterness, says: "Who says the bitter herb is bitter$15 Compared to the bitterness in my heart, it is as sweet as shepherd's purse"—using the "bitterness" of the bitter herb to set off, by contrast, the "bitterness" of human life, so that the bitterness of the herb becomes, in comparison, "sweetness." What a profound and poignant technique this is, using the bitterness of taste to write of the bitterness of life!

From this we can see that "bitterness," in the Book of Songs and in the hearts of our ancestors, was never merely a matter of taste, but a symbol of the very flavor of human existence. That "the bitter herbs flourish" at Xiaoman places this character "bitter"—so charged with the texture of life and the philosophy of existence—at the very season when all things are approaching fullness, letting abundance and bitterness, hope and hardship, intertwine and resonate within one and the same solar term. This is precisely our ancestors' most truthful and most profound recognition of life—fullness never arrives out of nowhere; it always grows out of the tempering of bitterness.

Chapter 9 · The Second Pentad: The Mi Grass Dies—The Principle of Waxing and Waning Behind "Yin Beings Dying When They Sense Yang"

I. "The Mi Grass Dies": The Phenological Reality of the Second Pentad

The second pentad of Xiaoman is "the mi grass dies" (靡草死).

Commentators have long disagreed on the meaning of "mi grass" (靡草). A relatively common interpretation (elaborated by Zheng Xuan and Kong Yingda in their commentaries on "the mi grass dies" in the "Monthly Ordinances" of the Book of Rites) holds that "mi grass" refers to plants such as pepperwort and shepherd's purse—grasses with soft, slender, delicate stems and leaves. Such grasses grow during winter and spring, yet, by early summer, when yang qi becomes greatly abundant, they wither and die instead.

"The mi grass dies" means that, by Xiaoman, these soft and delicate "mi grasses" wither and die, one after another.

Here we encounter an extraordinarily anomalous, and extraordinarily profound, phenological phenomenon: at the very Xiaoman season when all things are growing vigorously, everywhere attaining "a small fullness," there is, of all things, a category of grass that is "dying"! While other plants strive with all their might to grow, the mi grass alone moves in the opposite direction, heading toward death at the very moment when vitality is at its most abundant. Why should this be so$16

II. "Yin Beings Dying When They Sense Yang": A Profound Demonstration of the Waxing and Waning of Fullness and Emptiness

Our ancestors' explanation of "the mi grass dies" touches upon the most central law of the waning and waxing of yin and yang.

Zheng Xuan's commentary on the "Monthly Ordinances" of the Book of Rites, together with the common interpretation of successive generations of scholars of the monthly ordinances, holds that the mi grass belongs to "yin"—its stems and leaves being soft, slender, and delicate, of a yin and yielding nature, growing during winter and spring, when yin qi still remains. By Xiaoman, however, yang qi becomes greatly abundant and yin qi greatly diminished—and these "mi grasses," which were born endowed with yin qi, cannot survive amid such vigorous yang qi, and so, sensing the flourishing of yang qi, they die. What is called "the mi grass dies" is, in essence, "a yin being sensing the flourishing of yang and dying."

What a profound phenological philosophy this is! It demonstrates for us the irresistible force of "the waxing and waning of fullness and emptiness"—when yang qi becomes "full" (flourishing) to the degree found at Xiaoman, yin qi becomes "empty" (diminished) to the degree at which the mi grass can no longer survive. The death of the mi grass is not due to any fault of its own, but because the great trend of the qi of Heaven and Earth has already shifted—yang flourishing, yin declining; and whatever is born endowed with yin perishes along with the decline of yin qi.

This leads us to an insight that deeply resonates with the theme of "Xiaoman": the waxing and waning of fullness and emptiness is merciless and absolute. The "fullness" of yang qi is inevitably accompanied by the "emptiness" of yin qi; the "fullness" of one side is inevitably accompanied by the "deficiency" of the other. This is precisely a living demonstration of the Book of Changes, hexagram Feng: "the fullness and emptiness of Heaven and Earth wax and wane with the times." The mi grass is a silent footnote within this great cosmic drama of "the waxing and waning of fullness"—through its own death, it marks the degree to which yang qi has become full and flourishing.

III. Why Must Death Appear at the Point of Fullness at Its Extreme$17—Another Layer of Warning About "Fullness"

"The mi grass dies" also deepens, from another angle, the warning behind "small fullness with no great fullness."

Consider this carefully: why, at Xiaoman, a time when yang qi is so "full" and all things so flourishing, should a phenological sign of "death" (the mi grass dying) be arranged, of all things$18 Does this not spoil the mood$19

Quite the opposite—this is precisely our ancestors' great wisdom. At the very moment when all things are attaining "a small fullness," a scene of universal flourishing, our ancestors chose, of all things, "the mi grass dies" to remind the human world: within fullness, the seeds of death already lie hidden; beneath flourishing, decline is already present. The more abundant the yang qi, the more yin beings wither; the more vigorous the vitality, the more inevitable the death of certain things.

This is yet another profound warning about "fullness." It tells us: there is no such thing as pure, shadow-free "fullness." Every fullness comes at the cost of some other party's loss; within the depths of every flourishing, the seeds of decline are already germinating. Once we understand this, we ought to maintain, all the more, a sober-minded restraint when facing "fullness"—not to be deceived by surface flourishing, not to covet that seemingly flawless "great fullness," because behind "great fullness" often lies an even greater "death" (decline) drawing near.

"The mi grass dies" and "the arrogant dragon has cause for regret" are two expressions of one and the same truth. "The arrogant dragon has cause for regret" says that when yang qi reaches fullness at its extreme (great fullness), misfortune follows; "the mi grass dies" says that when yang qi becomes full and flourishing, yin beings die—both reveal the Dao of Heaven's principle that "when fullness reaches its extreme, there must be some loss; when fullness reaches its utmost, there must be some deprivation." Our ancestors' letting all things pause at "small fullness" was precisely to prevent that killing force lurking within "fullness at its extreme" (such as the arrogant dragon's regret, such as the mi grass's death) from developing to the point of consuming all things.

IV. What "The Mi Grass Dies" Reveals About Our Ancestors' Attitude Toward Death

This phenological sign of "the mi grass dies" also reflects a broad-minded and profound attitude toward "death" held by our ancestors.

In the cosmology of our ancestors, death was not an absolute end, but a single link within the cycle of "the waxing and waning of fullness and emptiness." The mi grass dies at Xiaoman, but its death clears space for the flourishing of other life forms in the summer and autumn to come; it dies this year, but next year, when yin qi rises again, grasses of its own kind will grow once more. Death and new life, within the great cycle of "waxing and waning with the times," transform into one another, ceaselessly generating and regenerating.

The "Perfect Enjoyment" (Zhi Le) chapter of the Zhuangzi records that when Master Zhuang's wife died, Huizi came to offer condolences, only to find Master Zhuang "sitting with legs sprawled, drumming on a basin and singing." Huizi rebuked him for this, and Master Zhuang replied: "Examining her beginning, I see that originally she had no life; not only no life, but originally no form; not only no form, but originally no qi. Mingled together in the vague and indistinct, it changed and there was qi; the qi changed and there was form; the form changed and there was life; and now, changing once more, there is death. This is like the progression of the four seasons—spring, autumn, winter, and summer" (察其始而本无生，非徒无生也而本无形，非徒无形也而本无气。杂乎芒芴之间，变而有气，气变而有形，形变而有生，今又变而之死，是相与为春秋冬夏四时行也)—human life and death, he says, are as natural as the progression of the four seasons, spring, summer, autumn, and winter.

Master Zhuang's broad-minded view that "life and death are like the four seasons" illuminates precisely the deeper meaning of "the mi grass dies." That the mi grass dies at Xiaoman is simply one link in its own "progression along with the four seasons"—as natural as winter giving way to spring, or summer's flourishing giving way to autumn's decline. Our ancestors placed "the mi grass dies" among the pentads of Xiaoman not to dwell mournfully on death, but to reveal the ceaseless Dao of Heaven's cycle of life, death, fullness, and emptiness—at the very moment when all things are full, reminding people not to forget decline; and in witnessing death, at the same time revealing the hope of cyclical renewal. This broad-minded recognition of the cycle of life, death, fullness, and emptiness is one of the most profound wisdoms of Chinese civilization.

Chapter 10 · The Third Pentad: Wheat's Autumn Arrives—The Temporal Mystery That Ripeness Itself Is "Autumn"

I. "Wheat's Autumn Arrives": The Phenological Reality of the Third Pentad

The third pentad of Xiaoman is "wheat's autumn arrives" (麦秋至).

At first glance, the three characters "wheat's autumn arrives" seem puzzling—Xiaoman is plainly early summer (the fourth lunar month), so how could there be "autumn"$20 What, exactly, is this "wheat's autumn"$21

Commentators through the ages have offered a precise explanation. The so-called "wheat's autumn" does not refer to the autumn season at all, but to "the season when the wheat ripens." Wu Cheng of the Yuan dynasty, in the Collected Explanations of the Seventy-Two Pentads of the Monthly Ordinances, explains: "Wheat's autumn arrives. 'Autumn' is the period when the hundred grains ripen. Though this is summer in terms of the season overall, for the wheat it is its autumn—hence it is called 'wheat's autumn'" (麦秋至。秋者，百谷成熟之期。此于时虽夏，于麦则秋，故云麦秋也). "Autumn" is the period when the hundred grains ripen. Although this season is, overall, summer, for the wheat specifically it is its "autumn" (its period of ripening)—hence the name "wheat's autumn."

The truth is now clear: "wheat's autumn arrives" means that, by the end of Xiaoman, the wheat is about to ripen, and the wheat's own "autumn of harvest" has arrived.

Yet hidden behind this explanation lies a mystery capable of shaking our very conception of time—it turns out that the character "autumn" (秋), in its original meaning, did not refer to a season at all, but to "ripening"!

II. The Original Meaning of "Autumn": Ripening, Not a Season

This is the greatest insight offered by this pentad, "wheat's autumn arrives"—it reveals the original meaning of the character "autumn."

The "autumn" we understand today is the third of the four seasons of the year, a concept of time. But "wheat's autumn arrives" tells us: to our ancestors, "autumn" was, first and foremost, a concept of "ripening," not a concept of "season."

Why does "autumn" carry this original meaning of "ripening"$22 Etymologically, the character qiu (秋, "autumn") is composed of "grain" (禾) and "fire" (火) (ancient graphic forms are sometimes said to derive from "tortoise" or "cricket," accounts vary, but "grain" is undoubtedly its core semantic component); its original meaning is closely bound up with the ripening of grain crops. When grain ripens, its color turns golden, like fire—hence qiu is composed of "grain" and "fire." Within the year, grain crops (millet and the like, the staple grains) ripen in the third season, and so this original meaning of "grain ripening" was extended and fixed as the seasonal meaning of "the third season."

In other words, the logical chain behind "autumn" runs: grain ripening (original meaning) → the season in which grain ripens (extended meaning) → the third season (fixed seasonal meaning). Today we know only the seasonal meaning of "autumn," and have forgotten that its original meaning was "ripening." This pentad, "wheat's autumn arrives," precisely preserves that most primal meaning of "autumn" as "ripening"—the ripening of the wheat is the wheat's own "autumn," even though the season, plainly, is summer.

What an astonishing discovery this is! A seemingly ordinary phenological name, "wheat's autumn arrives," has, it turns out, preserved for us the most ancient original meaning of the character "autumn," allowing us a glimpse into our ancestors' primal way of thinking when they coined characters—"naming the sequence of time after ripening."

III. The Relativity of Time: Every Crop Has Its Own "Autumn"

"Wheat's autumn arrives" also reveals a profound philosophical proposition—the relativity of time.

Since the original meaning of "autumn" is "ripening," every crop has its own "autumn" (its period of ripening). The wheat's "autumn" falls in early summer (around Xiaoman); the rice's "autumn" falls in mid-autumn; melons and fruits each have their own "autumn." "Autumn" is not an absolute time fixed to a particular season, but a differently timed "moment of ripening," relative to the maturation rhythm of each individual form of life.

What a dialectically wise conception of time this is! In the view of our ancestors, time was not a homogeneously flowing "absolute time" that treats all things equally, but a "relative time" profoundly bound to the growth rhythm of each individual life. The very same physical moment (Xiaoman) is "autumn" (ripening) for the wheat, yet "spring" (sowing) for the rice; it is "death" for the mi grass, yet "flourishing" (xiu) for the bitter herb. All things have their own respective times, their own respective "springs, summers, autumns, and winters," which need not necessarily align with the astronomical four seasons.

This relative conception of time, in which "all things have their own respective times," resonates deeply with Master Zhuang's wisdom of "the equality of things." The "Free and Easy Wandering" (Xiaoyao You) chapter of the Zhuangzi states: "Small knowledge does not reach to great knowledge; a short lifespan does not reach to a long one. How do we know this is so$23 The morning mushroom does not know the alternation of dusk and dawn; the cicada that lives but a season does not know the alternation of spring and autumn—these are short lifespans. South of the state of Chu there is a creature called Mingling, for which five hundred years make one spring, and five hundred years make one autumn; and in remotest antiquity there was a great tree called Chun, for which eight thousand years made one spring, and eight thousand years made one autumn" (小知不及大知，小年不及大年。奚以知其然也？朝菌不知晦朔，蟪蛄不知春秋，此小年也。楚之南有冥灵者，以五百岁为春，五百岁为秋；上古有大椿者，以八千岁为春，八千岁为秋).

The mushroom that is born in the morning and dies by evening knows nothing of the passing of a month; the cicada that lives through spring and dies in summer, or lives through summer and dies in autumn, knows nothing of the passing of a year's spring and autumn—these are "short lifespans." Yet Mingling takes five hundred years as one spring, five hundred years as one autumn; and the great tree Chun takes eight thousand years as one spring, eight thousand years as one autumn—these are "long lifespans." The very same "spring and autumn," for the morning mushroom, the short-lived cicada, Mingling, and the great tree Chun, turns out to differ as widely as Heaven from Earth!

This passage of Master Zhuang's, and the "relativity of time" revealed by "wheat's autumn arrives," are one and the same profound insight. "Autumn" (ripening) differs for the wheat, for the rice, for Mingling, for the great tree Chun. Time is not absolute, but relative to the rhythm of each individual life. This seemingly ordinary pentad, "wheat's autumn arrives," conceals within it so profound a philosophy of time—it reminds us: do not measure the "time" of all things by one's own "time" alone; all things have their own ripening, their own "autumn."

IV. "Wheat's Autumn" and "Xiaoman": The Resonance of Ripening Approaching but Not Yet Arrived

"Wheat's autumn arrives," as the final pentad of Xiaoman, forms an exquisite resonance with the central theme of "Xiaoman" itself.

Note that this third pentad says "wheat's autumn arrives" (麦秋至)—the wheat's autumn of ripening is about to arrive—rather than "the wheat has ripened" or "the wheat may be harvested." During the Xiaoman stage, the wheat is "approaching ripeness but not yet ripe"—it is filling out, becoming plump (small fullness), and about to ripen (wheat's autumn approaching), but has not yet reached the true state of "great fullness" (fully ripe, ready for harvest). The wheat's true ripening and readiness for harvest must wait for the next solar term, Mangzhong.

This, too, is a state of "approaching but not yet arrived"! Wheat's autumn "arrives" (approaches), but the wheat has "not yet ripened" (not yet complete). Xiaoman pauses precisely at this threshold of "wheat's autumn approaching, but the wheat not yet fully ripe"—brimming with the hope of an imminent harvest, yet still restrained, unwilling to declare completeness.

From this we can see that Xiaoman's three pentads—"the bitter herbs flourish" (sweetness gestating within bitterness), "the mi grass dies" (loss lurking within fullness), and "wheat's autumn arrives" (approaching ripeness but not yet ripe)—build upon one another in successive layers, each from a different angle jointly setting off the core mood of "Xiaoman": approaching fullness but not yet full, leaving room to spare. The bitterness of the bitter herb is the tempering that precedes abundance; the death of the mi grass is the warning within fullness; the arrival of wheat's autumn is the restraint before ripening. Taken together, the three pentads form a complete philosophical portrait of "Xiaoman."

V. What "Wheat's Autumn Arrives" Reveals About the Urgency and Composure of Farm Work

"Wheat's autumn arrives" also leads us to the most important human affair of the Xiaoman season—preparation for the summer harvest.

"Wheat's autumn arrives" means that the summer harvest (reaping the wheat) is now imminent. A farming proverb says, "If Xiaoman is not full, the wheat faces a risk" (小满不满，麦有一险), and another says, "By Xiaoman, the wheat turns golden day and night" (麦到小满日夜黄). During Xiaoman, the wheat ripens to a golden color a little more each day, and the farmer's heart grows a little more anxious with each passing day as well—looking forward to the harvest, yet also worrying whether, at this threshold of "approaching ripeness but not yet ripe," wind, rain, or hail ("the wheat faces a risk") might strike, destroying a harvest so nearly within reach.

This state of mind—tension and composure coexisting amid a harvest "approaching but not yet gathered"—is precisely the human portrait of the spirit of "Xiaoman." On the one hand, the harvest is in sight, brimming with hope (fullness); on the other, it is not yet in hand, and one dares not let down one's guard (not yet full). The farmer's complex mood at Xiaoman—filled with anticipation, yet treading as if on thin ice—is the truest lived experience of the philosophy of "Xiaoman," of "approaching fullness but not yet full." Our ancestors crystallized this urgency and composure of "approaching ripeness but not yet ripe" into the pentad "wheat's autumn arrives," and likewise crystallized it into the very naming of "Xiaoman" as a whole.

Chapter 11 · Yin-Yang and the Five Phases: Fire Virtue Approaching Its Extreme and the Mechanism of Transition Between Fullness and Emptiness

I. Yang Qi Full and Flourishing: The Position of Xiaoman in the Waxing and Waning of Yin and Yang

Viewed from the macroscopic perspective of the waxing and waning of yin and yang, Xiaoman occupies the critical stage where yang qi is "full and flourishing, approaching its extreme."

Across the year, yang qi begins its return with the birth of a single yang line at the Winter Solstice, and grows in succession: passing through Lichun (Beginning of Spring) and the Spring Equinox (yin and yang in balance), yang qi passes the halfway point; passing through Lixia, yang qi is already flourishing; by Xiaoman, yang qi is "full and flourishing, approaching its extreme"; by the Summer Solstice, yang qi reaches its utmost flourishing (yang at its extreme), whereupon a single yin line begins to be born.

Xiaoman's position within this sequence is "yang flourishing but not yet at its extreme." It has already far surpassed the Spring Equinox's balance of yin and yang, and is rapidly approaching the Summer Solstice's extreme of yang—yet it has not yet reached that turning point of "yang at its extreme, yin being born."

This position of "yang flourishing but not yet at its extreme" is entirely consistent with the literal meaning of "Xiaoman," with hexagram Qian's "six yang lines approaching fullness but not yet triggering yin's birth" among the twelve sovereign hexagrams, with the sun's shadow "approaching its shortest but not yet there," and with Fire virtue "approaching its extreme but not yet there." All of these dimensions point toward one and the same state—"approaching the extreme but not yet at the extreme." This is by no means mere coincidence, but a consistent grasp, from different angles (etymology, hexagram imagery, astronomy, the Five Phases), of one and the same great cosmic trend, under our ancestors' cosmology of "the unity of Heaven and humanity." In the eyes of our ancestors, the waxing and waning of the qi of Heaven and Earth was a single, unified process—no matter from which angle one approached it, what one saw was one and the same "Xiaoman."

II. Fire Virtue Approaching Its Extreme: From "The Flourishing Virtue Lies in Fire" to "Yang at Its Extreme, Yin Being Born"

We have already discussed how the first month of summer is correlated with the virtue of Fire. Here, we shall elaborate particularly on the trend of Fire virtue "approaching its extreme" at this specific point of Xiaoman, and on the "transition between fullness and emptiness" that it foretells.

At Lixia, "the flourishing virtue lies in Fire"—Fire virtue begins to flourish; by Xiaoman, Fire virtue has advanced further, full and flourishing, approaching its extreme; by the Summer Solstice, Fire virtue (yang qi) reaches its utmost flourishing. And the very moment "Fire virtue reaches its utmost flourishing" is precisely the mechanism by which "yin qi begins to be born" (a single yin line born at the Summer Solstice). This is the most profound dialectic of yin-yang and the Five Phases—any single "Phase," any single form of "qi," once it flourishes to its extreme, immediately turns into its opposite.

Xiaoman occupies the position where Fire virtue is "approaching its extreme but not yet there," precisely the eve of the transition between fullness and emptiness, "approaching but not yet arrived." It enjoys the full benefits of Fire virtue's fullness and flourishing (all things growing vigorously, the wheat kernels filling with grain), yet, through the restraint of "small fullness," avoids the turning point of "Fire at its extreme, yin being born." This is Fire virtue's most glorious, and also its safest, moment—one step before flourishing reaches its utmost extreme, the turning point not yet having begun.

Viewed in this light, "small fullness with no great fullness" appears all the more far-sighted. Were there such a thing as "great fullness," it would correspond to the "utmost flourishing" of Fire virtue (the extreme of yang at the Summer Solstice), to the turning point of "yang at its extreme, yin being born," to the perilous cliff of transition between fullness and emptiness, where utmost flourishing gives way to decline. Our ancestors' abolition of "great fullness," letting all things pause at "small fullness" (Fire virtue approaching its extreme but not yet there), was precisely to let all things remain one step before the very summit of "fullness"—there, everything still lies within the ascending channel of "fullness," not yet having fallen into the descending channel of "emptiness."

III. Bitterness, the Scorched Smell, and the Note Zhi: The Unity of Fire Virtue's Various Manifestations at Xiaoman

Let us return once more to the Five Phases correlations of the Monthly Ordinances, and, from the perspective of "Fire virtue approaching its extreme," reexamine those several correlations associated with Fire, to see how they unite into a single whole during the Xiaoman season.

"Its flavor is bitter"—as Fire virtue approaches flourishing, bitter things (the bitter herb) put forth their flowers in season, using bitterness to clear Fire. This is Fire virtue in the dimension of taste.

"Its smell is scorched"—the scorched smell is the qi of something burned by fire; among the five smells (goaty, scorched, fragrant, fishy, putrid), the scorched smell carries the strongest sense of "heat," corresponding to the dry heat of Fire virtue approaching flourishing. This is Fire virtue in the dimension of smell.

"Its note is zhi"—among the five notes (gong, shang, jue, zhi, yu), the note zhi is the most impassioned and high-pitched, its tonal quality corresponding to the fervor of Fire. Our ancestors believed that, in summer, the vibrational frequency of the qi of Heaven and Earth resonated with the note zhi. This is Fire virtue in the dimension of hearing.

The "bitterness" of taste, the "scorched smell" of smell, the note "zhi" of hearing—three different senses, under the single unifying cosmic energy of Fire virtue, sound out one and the same movement of "summer." And Xiaoman is precisely the passage of this movement gradually building toward its climax (Fire virtue approaching its extreme). The bitterness of the bitter herb is on the tip of the tongue, the dry, scorched qi is at the tip of the nose, the impassioned note zhi resonates between Heaven and Earth—everything speaks of Fire virtue's fullness approaching its extreme. This holistic perception, in which "the five senses connect to the Five Phases, and the Five Phases unite in a single qi," is precisely the most captivating aspect of our ancestors' cosmology of yin-yang and the Five Phases—it unifies scattered sensory experiences into a single, seamlessly connected cosmic portrait.

IV. "The Number Seven" and Fire: Reflections on Fullness and Emptiness Within a Number of Fullness

The Monthly Ordinances states that the first month of summer's "number is seven" (其数七). In pre-Qin numerology, one and six belong to Water, two and seven to Fire, three and eight to Wood, four and nine to Metal, and five and ten to Earth. Seven belongs to Fire, and so it correlates with summer.

This "seven" can also give rise to a further reflection on "fullness and emptiness." In the numerology of the Luo River Chart's nine palaces and the He River Diagram, each number carries its own symbolism. "Fullness" and "brimming," in numerology, are often associated with "extreme numbers" (such as nine or ten)—nine being the extreme number of yang, and ten being a number of fullness (a full, complete number).

It is worth noting that Fire virtue is correlated with "seven," rather than with "nine" or "ten," those numbers symbolizing "utmost fullness." Seven is a number that is "full but not yet at its extreme"—it is no longer small, yet has not yet reached the extreme number of yang (nine) or the number of fullness (ten). How this quietly resonates, once again, with the spirit of "Xiaoman"! Though Fire virtue is flourishing, its number is "seven" (full but not yet at its extreme), rather than "nine" or "ten" (utmost fullness). This seems to corroborate, even at the numerological level, that however flourishing Fire virtue becomes, it ought still to hold to its "seven" (small fullness), rather than covet its "nine" or "ten" (great fullness).

Of course, such a numerological correspondence may seem somewhat forced, but it at least suggests to us: in our ancestors' cosmology, in which "all things are number," even numbers themselves were steeped in the philosophy of the waxing and waning of fullness and emptiness. "Seven," in relation to Fire and to summer, is not a cold symbol, but an expression, in the numerological dimension, of that state in which the qi of Heaven and Earth is "full but not yet at its extreme." Our ancestors' fondness for "small fullness," and their avoidance of "great fullness," turns out to resonate faintly, too, with this numerological arrangement—yet further evidence of the "consistency running through all things" (一以贯之) within the Chinese cosmology.

Chapter 12 · Agriculture and Human Affairs: The Wheat Approaching Ripeness, the Rush to Harvest, and the Anxiety of Fullness

I. "If Xiaoman Is Not Full, the Wheat Faces a Risk": Anxiety on the Eve of Harvest

Farm work during the Xiaoman season centers on a single character—"wheat" (麦). At this time, the wheat is filling with grain and growing plump (small fullness), about to ripen (wheat's autumn arrives), and all agricultural activity revolves around this wheat, "approaching ripeness but not yet ripe."

The farming proverb "if Xiaoman is not full, the wheat faces a risk" (小满不满，麦有一险) captures fully the distinctive anxiety in the hearts of farmers during this season. "If Xiaoman is not full"—if, by Xiaoman, the wheat kernels have not yet attained their due plumpness (fullness), this portends a poor year and an anxious wheat harvest. And "the wheat faces a risk"—even if the wheat is plump, at this threshold of "approaching ripeness but not yet ripe," danger still lurks everywhere: a hailstorm, a violent gust of wind, a stretch of continuous rain (the wheat harvest's "three fears: wind, rain, and hail") could, in an instant, reduce a harvest so nearly within reach to nothing.

This state of mind—a harvest in sight, yet fraught with anxiety—is precisely the most profound human corroboration of the philosophy of "Xiaoman." It tells us once again: fullness was never a secure, worry-free state. The closer one draws to "fullness" (harvest), the more variables and risks abound. The eve of "fullness" is precisely the moment demanding the greatest vigilance, the moment one can least afford to relax. This finds its plainest, and truest, verification in the fields, corroborating the wisdom of the Dao of Heaven found in "fullness invites loss," "fullness brings overturning," and "the arrogant dragon has cause for regret."

II. The Rush to Harvest: Racing Against Heaven's Timing

Xiaoman is followed by Mangzhong, and "Mangzhong" means that the summer harvest (reaping the wheat) is now in full swing. Therefore, during the Xiaoman season, farmers have already entered a tense state of "rushing to prepare for the harvest."

Why the rush$1 Because the wheat's ripening has an extremely narrow window. "By Xiaoman, the wheat turns golden day and night"—once the wheat turns golden and ripe, it must be harvested within an extremely short span of time. Harvested too early, the kernels are not yet full, reducing the yield; harvested too late, the kernels shed from the ear, or rot after rain, likewise reducing the yield or even causing total crop failure. Farmers must precisely grasp that moment when the wheat is "just ripe, just ready to harvest," racing against Heaven's timing down to the very minute.

This precise grasp of "just the right moment" is precisely the agricultural embodiment of the wisdom of "timely centrality" (时中) that Confucius extolled. Too early (wheat not yet ripe) will not do; too late (wheat already shed) will not do either—one must hit "the mean" (中), acting precisely at that critical threshold. What farmers display at wheat harvest time is precisely a practical wisdom of "grasping the two extremes and applying the mean"—precisely calibrating, between "excess" (harvesting too late) and "deficiency" (harvesting too early), that "just right" moment of harvest.

And Xiaoman is precisely the prelude to this "rush to prepare for the harvest." During the Xiaoman season, farmers tend the ripening wheat with one hand, while, with the other, repairing farm tools (sickles, stone rollers, winnowing shovels), leveling the threshing ground, and arranging labor—all in preparation for the imminent, minute-by-minute race of the summer harvest. This kind of preparation, "mending the roof before the rain," embodies our ancestors' sober-minded attitude toward "fullness" (the harvest)—however good fullness may be, to gather it in securely, one must make thorough preparations already at the moment of "approaching fullness."

III. The Lean Season: Scarcity Before Fullness

The Xiaoman season also holds another agricultural reality, often overlooked yet deeply philosophical—the "lean season" (青黄不接, literally "the green not yet connecting with the yellow").

The so-called "lean season" refers to the period when the new wheat in the fields (green) has not yet ripened for harvest, while the old grain in the granary (yellow) has already been consumed—this is the most difficult, most scarce period of the year for a farming household. And Xiaoman falls precisely at this juncture of the "lean season"—even as the fields, brimming with wheat (green), are about to yield a harvest, the household's hands are already empty of surplus grain (yellow).

What a profound paradox this is! At the very season when all things attain "a small fullness" and a harvest is in sight, the farming household itself finds itself in the most scarce, most famished of circumstances. The "fullness" of "Xiaoman" (the fullness of the fields) and the "emptiness" of the farming household (the emptiness of the granary) coexist, sharply juxtaposed, within one and the same season.

It is precisely against this backdrop of the "lean season" that "the bitter herbs flourish," discussed earlier, reveals the compassion of Heaven and Earth—at Xiaoman, when the farming household has no grain left to eat, Heaven and Earth produce, of all things, an abundance of the bitter herb, which can fill an empty stomach. The bitter herb, gathered by our ancestors and used as firewood substitute to feed the farmers, is precisely the "bridging grain" that relieves famine during the lean season.

This reality of the "lean season" once again deepens the mood of "Xiaoman"—"approaching fullness but not yet full." It tells us: the eve of fullness (harvest) is often not ease, but scarcity and hardship; the moment closest to harvest is often also the most difficult moment. Our ancestors had the most visceral understanding of this—they knew that "fullness" had to be purchased with "emptiness" (the hardship of the lean season), and that harvest had to be awaited through hardship. This profound recognition that fullness is hard-won is precisely the root of the Chinese agricultural spirit of "laboring anxiously, ever vigilant, never daring to be complacent."

IV. The Portrait of Summer Farm Work in "Qi Yue" from the "Airs of Bin" in the Book of Songs

To understand the farm work and state of mind of our ancestors around the time of Xiaoman, "Qi Yue" ("The Seventh Month") from the "Airs of Bin" in the Book of Songs is the most precious of texts. This long poem, arranged month by month, lays out the farm work and daily life of all four seasons of the year.

The poem's description of early summer (roughly corresponding to the time around Xiaoman) includes the lines: "In the fourth month the yao plant flowers; in the fifth month the cicada sings" (四月秀葽，五月鸣蜩)—in the fourth month the milkwort flowers (xiu), and in the fifth month the cicadas begin to sing. There are also the lines "In the fifth month the grasshopper stirs its legs; in the sixth month the katydid flutters its wings" (五月斯螽动股，六月莎鸡振羽)—in the fifth month the grasshopper rubs its legs (chirping), and in the sixth month the katydid flutters its wings. These meticulous phenological records embody the very same spirit of "revering Heaven, observing things closely" as the phenological observations of Xiaoman's "the bitter herbs flourish," "the mi grass dies," and "wheat's autumn arrives."

What is most moving throughout the whole of "Qi Yue" is the sentiment of laboring anxiety that runs through it from beginning to end—"without robes, without coarse cloth, how shall we get through the year$2"; "Alas for us farmers—once our harvest is gathered in, we must still go into the city to labor in service." The farmer toils ceaselessly the whole year round, and even after the crops are harvested must still travel into the city for corvée labor, anxious over how to survive the winter without adequate clothing. This "laboring anxiety" is precisely the underlying tone of our ancestors' agricultural life, and the spiritual root of their refusal to be complacent. Amid such an arduous struggle for survival, our ancestors understood well that even the smallest measure of "fullness" was hard-won, and had to be striven for and protected with redoubled diligence and caution—how, then, could they dare covet that illusory "great fullness"$3 The image, in "Qi Yue," of the farmer laboring the whole year through, never daring the slightest relaxation, is the most vivid personification of the spirit of "Xiaoman"—full yet not overflowing, laboring anxiously and ever vigilant.

Chapter 13 · Cultivating Body and Mind: The Way of Health Cultivation and Self-Cultivation for "Full Yet Not Overflowing"

I. Health Cultivation in Summer: "Let the Will Know No Anger" and the Way of "Nurturing Growth"

Health cultivation during the Xiaoman season must accord with the season's natural trend, in which Fire virtue is approaching flourishing and yang qi is full and abundant.

The "Great Treatise on Regulating the Spirit in Accordance with the Four Seasons" (Si Qi Tiao Shen Da Lun), in the "Basic Questions" (Suwen) of the Yellow Emperor's Inner Canon (Huangdi Neijing, whose thought largely descends from the pre-Qin schools of yin-yang and Daoism), discusses summer health cultivation thus: "The three months of summer are called flourishing and blooming. The qi of Heaven and Earth intermingle, and all things flower and bear fruit. One should retire late and rise early, without wearying of the long days; let the will know no anger, let the spirit bloom splendidly like a flower, let the qi find release, as though one's affections lay all outward-facing—this is the response fitting to summer's qi, the way of 'nurturing growth'" (夏三月，此谓蕃秀，天地气交，万物华实，夜卧早起，无厌于日，使志无怒，使华英成秀，使气得泄，若所爱在外，此夏气之应，养长之道也).

The three months of summer are called "flourishing and blooming"—plants and trees grow luxuriant, flowers and fruit both abundant. The qi of Heaven and Earth intermingle, and all things flower and bear fruit. At this time one should retire late and rise early, not weary of the long daylight hours, let one's disposition avoid brooding anger, let one's spirit bloom splendidly like a flower, let the yang qi find its release, as though placing everything one cherishes out in the open—this is the method of according with summer's qi, of "nurturing growth."

Note the four characters "let the will know no anger" (使志无怒). In summer, Fire virtue holds sway, and Fire qi most easily ignites a person's "fire of anger." During the Xiaoman season, yang qi is full and abundant, and people, too, easily become restless and short-tempered. Yet the essence of health cultivation lies precisely in "letting the will know no anger"—at the very season when yang qi is at its most flourishing, most easily excited, one must instead keep one's heart and will calm and even, not letting "Fire qi" (anger) grow excessive.

This wisdom of health cultivation, "letting the will know no anger," is precisely the embodiment, at the level of body and mind, of the philosophy of "full yet not overflowing." Though Fire virtue (yang qi) is flourishing, the human heart must not follow it into "overreaching" (anger); though yang qi is full, one's disposition must maintain a measure of "restraint" (no anger). At the very season when one is most prone to "inflammation," most prone to "fullness" (excitability), one must instead cultivate a calm that is "not overflowing"—this is precisely "Xiaoman" in the version of body and mind.

II. "Diminish Rich Flavors, Moderate Cravings and Desires": Restraint at the Moment of Fullness and Flourishing

The "Monthly Ordinances" of the Book of Rites requires that the Son of Heaven, in the first month of summer, "diminish rich flavors, avoid excessive seasoning, moderate cravings and desires, settle the heart and qi, keep the hundred officials tranquil, refrain from carrying out punishments in governance, so as to settle the course by which the shaded yin is to come to completion" (薄滋味，毋致和，节嗜欲，定心气，百官静，事毋刑，以定晏阴之所成).

Diminish the richness of one's food and drink, do not over-season the five flavors, moderate one's cravings and desires, settle the qi of one's heart and mind, let the hundred officials remain tranquil, do not carry out punishments in matters of governance—so as to settle the trend by which the yin qi, soon to be born, will come to completion.

Why, in the first month of summer, when yang qi is at its most flourishing, should one instead "diminish rich flavors and moderate cravings and desires"$4 This seems contradictory, yet is in fact profound. Precisely because, in summer, yang qi is full and abundant and Fire virtue holds sway, a person's desires, cravings, and disposition all too easily swell along with it (fullness, brimming). Were one, at this time, to further indulge one's appetites and cravings, this would be "adding oil to the fire"—making the already full and flourishing yang qi still more excessive, inevitably leading to illness. Hence the way of health cultivation runs precisely counter to this trend at the moment of yang qi's fullness and flourishing, using "diminishment," "moderation," and "settling" to restrain that trend toward fullness and flourishing.

"Diminish rich flavors, moderate cravings and desires" is precisely the practice, in health cultivation, of "to hold a vessel and fill it to the brim is not as good as stopping in time." The yang qi of Heaven and Earth has already become "full" (summer); were a person to further indulge their desires and "hold the vessel and fill it to the brim" (adding oil to the fire), they would inevitably "overflow" (fall ill). The wise course is "to stop"—to moderate and draw inward, keeping one's body and mind in the state of "small fullness" rather than "great fullness."

Worth pondering is the phrase "so as to settle the course by which the shaded yin is to come to completion"—at the very moment yang qi is at its most flourishing, in the first month of summer, health cultivation must, of all things, focus on "settling that yin qi soon to be born." This resonates precisely with the principle of "yang at its extreme, yin being born"—the wise, at the very moment yang flourishes, are already preparing for that inevitable "birth of yin" (the coming turning point). This deeply accords with the spirit of "Xiaoman"—flourishing, yet knowing to guard against excess; full, yet contemplating emptiness.

III. The "Emptiness" of the Heart: Cultivating a Heart of "Xiaoman"

Moving from health cultivation to the cultivation of the heart-mind, the wisdom of "full yet not overflowing" ultimately points toward a heart that is "empty" yet capable of "holding."

We have already cited Master Zhuang's "the empty chamber gives birth to brightness," which makes clear that only an "empty" heart can "give birth to brightness" (give birth to wisdom). A heart that is self-satisfied (great fullness) is closed off, stagnant, incapable of receiving anything further; only a modest, humble heart (small fullness, seeming hollowness) can continually learn, continually grow, continually "give birth to brightness."

Confucius said: "The noble person is composed, yet not arrogant; the small person is arrogant, yet not composed" (君子泰而不骄，小人骄而不泰; Analects, "Zi Lu"). The noble person is at ease and composed, yet not arrogant; the small person is arrogant, yet not at ease and composed. "Arrogance" (骄) is a form of "fullness"—a psychological fullness of self-righteousness and disdain for all else. The noble person is "composed" (at ease and unhurried) precisely because they are "not arrogant" (not self-satisfied); the small person is "not composed" (cramped and uneasy) precisely because they are "arrogant" (self-satisfied). A person who is psychologically "greatly full" (arrogant) is, in fact, uneasy and precarious; only a person who is psychologically at "small fullness" (modest yet composed) is truly unhurried and secure.

Confucius further describes himself: "In learning, never satisfied; in teaching others, never wearied" (学而不厌，诲人不倦; Analects, "Shu Er")—never satisfied in learning, never wearied in teaching others. Even a sage such as Confucius was "never satisfied in learning" (never self-satisfied with the knowledge already possessed)—how much more should this apply to ordinary people$5 This spirit of "never satisfied in learning" is precisely the foundation of cultivating a heart of "Xiaoman"—forever feeling that one is "not yet full enough," and so forever learning, growing, filling. The moment one considers oneself "greatly full" (learning already sufficient) is the beginning of stagnation and decline.

Thus, the essence of cultivating the heart-mind lies in forever preserving a heart of "Xiaoman"—both substantial (not empty or lacking in confidence) and never self-satisfied (not arrogant, brimming, or stagnant). Such a heart is like the wheat ear at Xiaoman—already plump (possessing substance, accumulated depth), yet modestly bowing its head (the Caigentan says, "modesty is like the wheat ear—the fuller it grows, the lower it bows"), forever growing toward a still higher ripeness. A heart of "Xiaoman" is the most beautiful state of mind sought by the Chinese wisdom of self-cultivation.

IV. "Preserving Fullness, Guarding Peace": The Way of Protection at the Moment of Fullness

Chinese culture holds an extremely important proposition of self-cultivation—"preserving fullness, guarding peace" (持盈保泰). "Preserving fullness" (持盈) means protecting a fullness already attained; "guarding peace" (保泰) means safeguarding a peace and prosperity already attained. These four characters address, specifically, a profound question: once a person (or a family, or a state) has already reached a state of "fullness and peace," how is it to be protected, and made to last$6

The answer is, precisely, the wisdom of "Xiaoman"—full yet not overflowing, flourishing yet knowing to guard against excess.

In the Book of Changes, hexagram Tai (泰, Peace) is immediately followed by hexagram Pi (否, Stagnation)—"peace at its extreme gives way to stagnation" (泰极否来). How is "peace at its extreme giving way to stagnation" to be avoided$7 Precisely by never letting "peace" (fullness and prosperity) advance to its "extreme" (great fullness) while it is still "peace," but instead maintaining, at all times, modesty, restraint, and vigilance, keeping it in a stable state resembling "small fullness."

This is precisely the true meaning of "preserving fullness, guarding peace." At the moment of fullness and peace, the greatest danger comes not from without, but from the "self-satisfaction" within—once self-satisfaction sets in (great fullness), laziness, arrogance, and indulgence follow, and so "peace at its extreme gives way to stagnation," flourishing at its utmost turning to decline. Only by maintaining, even at the moment of fullness, the sober clarity of "Xiaoman"—thinking of danger while at peace, knowing to guard against excess while flourishing, contemplating emptiness while full—can one "preserve fullness and guard peace," making fullness and peace endure.

From this we can see that "Xiaoman" is not merely a solar term, but a fundamental wisdom running through personal cultivation, family continuity, and even the governance of a state. It tells everyone who has attained "fullness": what you most ought to guard against is precisely this "fullness" itself; and the only way to protect fullness is never to let it become "great fullness."

Chapter 14 · Ritual and Ceremony: Sacrificing to the Cart Spirit, Operating the Three Wheels, and the Custom of Guarding Against Fullness

I. The Folk Customs of Xiaoman: Sacrificing to the Cart Spirit and "Operating the Three Wheels"

The Xiaoman season carries many folk rituals and customs bound up with farm work, the most distinctive of which are "sacrificing to the cart spirit" (祭车神) and "operating the three wheels" (动三车).

The so-called "three wheels" refer to the waterwheel, the oil press wheel, and the silk-reeling wheel. The period around Xiaoman is precisely when these three agricultural implements come into their own—the waterwheel is used to irrigate the nearly ripe fields and the newly transplanted rice seedlings; the oil press wheel is used to press rapeseed oil (rapeseed being harvested at this time); and the silk-reeling wheel is used to reel silk (the work of sericulture entering its final stage at this point, the silkworms spinning and forming cocoons). Hence the saying "at Xiaoman, the three wheels are set in motion."

"Sacrificing to the cart spirit" is a ceremony performed before starting up the waterwheel, offering sacrifice to the spirit of the waterwheel. Tradition holds that the cart spirit is a white dragon; farmers place offerings such as fish, meat, incense, and candles at the base of the waterwheel and offer sacrifice, praying for abundant water sources and smooth irrigation. Especially interesting is that, during the sacrifice, farmers pour a cup of clear water into the field—symbolizing "water rising to fill the field," praying that the irrigation water will be as full and inexhaustible as the water thus poured out.

These folk customs, though they seem merely practical arrangements for farm work, are in fact deeply rooted in our ancestors' ritual tradition of "revering Heaven, serving the spirits." In the view of our ancestors, the turning of the waterwheel, the abundant harvest of rapeseed, and the yield of silk were never merely the result of human effort alone, but depended also on the protection of the spirits of Heaven and Earth. Through the ceremonies of sacrificing to the cart spirit and operating the three wheels, our ancestors elevated ordinary agricultural labor into a solemn act of "collaboration with the spirits of Heaven and Earth"—humanity does not struggle against nature in isolation, but respectfully requests the assistance of the spirits of Heaven and Earth.

II. "Fullness" and "Reverence" Within "Sacrificing to the Cart Spirit"

The ceremony of "sacrificing to the cart spirit," in which water is poured out to "pray for fullness," forms a subtle and profound resonance with the theme of "Xiaoman."

Consider this: the farmer pours water into the field, praying for the "fullness" (满) of irrigation water—this is a prayer for "fullness." But note that what they pray for is that "just right" fullness of "water rising to fill the field" (sufficient for irrigation), and certainly not the overflowing "spilling over" (溢) that brings disaster (a flood). This prayer for a "just-right fullness" resonates precisely with the measured sense of "full yet not overflowing" found in "Xiaoman"—what is sought is the "Xiaoman"-like water that nourishes all things, not the "great fullness" (flood) water that submerges the fields.

Going deeper still, the act of "sacrifice" itself is an expression of "guarding against fullness" and "knowing reverence." Farmers dare not attribute a good harvest entirely to their own effort, but instead respectfully sacrifice to the cart spirit and pray for divine blessing—this is a humility of "not being self-satisfied." They understand well that human effort has its limits, and Heaven's will is hard to fathom; only by maintaining reverence and awe toward the spirits of Heaven and Earth (not being self-satisfied) can a good harvest be prayed for. This devotion of "knowing reverence" and "not being self-satisfied" is precisely the embodiment, within ritual custom, of the "Xiaoman" spirit of guarding against fullness and prizing modesty.

The "Meaning of Sacrifices" (Ji Yi) chapter of the Book of Rites states: "Sacrifices should not be too frequent; if too frequent, they become tiresome, and tiresomeness leads to a lack of reverence. Nor should sacrifices be too sparse; if too sparse, they breed laxity, and laxity leads to forgetting" (祭不欲数，数则烦，烦则不敬；祭不欲疏，疏则怠，怠则忘). The frequency of sacrifice, too, must be calibrated to "the mean"—neither too frequent nor too sparse, but just right. This "mean" governing the timing of sacrifice is, once again, of a piece with the spirit of "Xiaoman"—"just right, neither excessive nor deficient."

III. The Coda of the Rite of the First Sericulturist: From "Personal Tending of Silkworms" to "Operating the Silk Wheel"

The "silk-reeling wheel" within Xiaoman's "operating the three wheels" leads us to an ancient and important ritual institution—the "Rite of the First Sericulturist" (先蚕之礼, also known as the "Rite of Personal Sericulture," 亲蚕之礼).

The work of sericulture and mulberry cultivation held an extremely high position in the economy and ritual system of our ancestors. The "Meaning of Sacrifices" chapter of the Book of Rites records: "In ancient times, the Son of Heaven and the feudal lords always maintained a public mulberry grove and a chamber for silkworm-rearing... and, on the morning of the great new moon, the ruler, wearing the leather cap and unadorned silk robe, would divine to select the most auspicious among the consorts and ladies of the three palaces, and have them enter the silkworm chamber to raise the silkworms" (古者天子诸侯必有公桑蚕室……及大昕之朝，君皮弁素积，卜三宫之夫人世妇之吉者，使入蚕于蚕室). In ancient times, the Son of Heaven and the feudal lords always maintained a public mulberry grove and silkworm chamber; and at a certain season, the ruler would reverently divine to select the most auspicious among the palace consorts and ladies, sending them into the silkworm chamber to raise the silkworms. Likewise, the "Monthly Ordinances" of the Book of Rites records that, in the third month of spring, "the queen consort fasts and purifies herself, and personally goes east to gather mulberry leaves" (后妃齐戒，亲东乡躬桑)—the queen consort personally gathers mulberry leaves facing east, to serve as a model for all the women of the realm.

The work of sericulture begins in the third month of spring (raising the silkworms), continues through the first month of summer (the silkworms growing, mounting the frames, spinning silk and forming cocoons), and, by the time around Xiaoman, the silkworms have already formed their cocoons, entering the stage of "reeling silk" (operating the silk wheel)—precisely the "ripening" and "harvest" of the sericultural season (the "autumn" of silkworm work). "Operating the silk wheel at Xiaoman" is precisely the folk continuation and coda of the Rite of the First Sericulturist.

Why was the work of sericulture and mulberry cultivation held in such regard, to the point that the Son of Heaven's consort personally took part in it$8 Because silk was the source of "clothing" (衣), and stood, together with "food" (食, farming), as the twin foundations of the people's livelihood. The Guanzi, in the opening of "Mu Min" ("Shepherding the People"), states: "When the granaries are full, people know propriety and moderation; when clothing and food are sufficient, people know honor and shame" (仓廪实则知礼节，衣食足则知荣辱). Clothing and food are the material foundation upon which ritual, righteousness, integrity, and a sense of shame can be established. And sericulture (the foundation of clothing) and farming (the foundation of food), during the Xiaoman season, simultaneously enter their critical stage of "approaching completion"—the wheat is nearly ripe, the silkworms have already formed their cocoons. That our ancestors sacrificed to the cart spirit, operated the three wheels, and carried on the Rite of the First Sericulturist during this season of "clothing and food approaching completion" was precisely to welcome, with the utmost solemnity, the arrival of this "small fullness of clothing and food," and, with a modest and reverent heart, to pray for and protect this hard-won fullness.

IV. The Foundation of Ritual: Maintaining Restraint and Reverence Amid Fullness

Surveying the various rituals and customs of Xiaoman as a whole, we can discern a spiritual thread running through them all—maintaining restraint and reverence at the approach of fullness (the harvest).

Confucius, discoursing on the foundation of ritual, said: "In rites, rather than extravagance, it is better to be frugal; in mourning, rather than thorough attention to form, it is better to feel true grief" (礼，与其奢也，宁俭；丧，与其易也，宁戚; Analects, "Ba Yi"). Rather than extravagance, ritual is better served by frugality; rather than an elaborately complete ceremony, mourning rites are better served by genuine sorrow of the heart. The foundation of ritual lies not in outward extravagant fullness, but in inward sincere restraint.

This spirit of "ritual prizing frugality, prizing true feeling" resonates deeply with the central theme of "Xiaoman"—guarding against fullness, prizing modesty. The various rituals and customs of Xiaoman—sacrificing to the cart spirit, operating the three wheels, continuing the Rite of the First Sericulturist—are, without exception, plain, restrained, and filled with reverence. At the approach of a good harvest, farmers do not display arrogant extravagance (great fullness), but instead offer reverent sacrifice, labor diligently, and manage their households frugally (small fullness). This restraint and reverence in the face of fullness is precisely the most profound spirit of Chinese ritual institutions—ritual, at its core, teaches people how to treat fullness, treat harvest, treat every "moment of triumph" in the "proper" way, so that people do not become arrogant and unrestrained on account of fullness.

From this we can see that "ritual" (礼) and "Xiaoman" are, in spirit, deeply interconnected. Ritual is the institutionalization and ceremonialization of the philosophy of "Xiaoman"—through an entire system of norms governing restraint, reverence, and the avoidance of overstepping bounds, it puts into practice, in people's daily conduct, the wisdom of "full yet not overflowing, guarding against fullness, prizing modesty." A person who truly "knows ritual" is necessarily also a person deeply versed in the way of "Xiaoman"—one who understands how to maintain that just-right restraint and reverence at every moment of fullness and triumph.

Chapter 15 · The World of Literature: The Bitter Herb, Waves of Wheat, and Poetry of Fullness and Emptiness

I. Wheat in the Book of Songs: From "I Walk Through the Wilds" to "Lush and Luxuriant the Wheat"

Wheat is the leading figure of the Xiaoman season, and also an image sung of again and again in the Book of Songs.

The Book of Songs, in "Zai Chi" from the "Airs of Yong," contains the line "I walk through the wilds, and the wheat grows lush and luxuriant" (我行其野，芃芃其麦)—I walk through the open wilderness, and see the wheat growing thick and abundant (pengpeng). These four characters, "lush and luxuriant the wheat," bring vividly to life that boundless, vigorous sea of wheat waves around the time of Xiaoman. This is the joy of a harvest in sight, a vivid portrait of "a small attainment of fullness."

The Book of Songs, in "Si Wen" from the "Hymns of Zhou," recounting the virtue of Hou Ji (the Lord of Millet), states: "He bestowed upon us wheat and barley; the Sovereign on High decreed that all be nourished thereby" (贻我来牟，帝命率育)—Hou Ji bestowed upon us wheat and barley (lai mou), and the Sovereign on High decreed that all the people be universally nourished by them. "Lai mou" refers to wheat, regarded as a gift bestowed upon the human world by the Sovereign on High (Heaven), the very foundation for nourishing all the people. From this we can see that, in the hearts of our ancestors, wheat was by no means an ordinary crop, but a "sacred thing" bearing the grace of Heaven and bound up with the very life of the people.

The timeless poem "Shu Li" from the "Airs of Wang" in the Book of Songs—which speaks of the millet hanging heavy, the sorghum's sprouts... the millet hanging heavy, the sorghum's ears... the millet hanging heavy, the sorghum's grain—though it sings of millet and sorghum, its technique of investing the growth of grain crops, from "sprout" to "ear" to "grain," with a sense of the rise and fall of states and homes, may equally be applied to the observation of wheat. The wheat's growth, from putting forth its ear (before Xiaoman) to filling with grain (Xiaoman) to ripening (Mangzhong)—this journey of "approaching fullness but not yet full"—is, in itself, a wordless poem of hope, anxiety, and harvest.

II. The Bitter Herb in Poetry: The Flavor of Life Within Bitterness

We have already discussed the image of the bitter herb in the Book of Songs; here let us savor it once more, from a literary angle.

The line "Who says the bitter herb is bitter$9 It is as sweet as shepherd's purse" from "Gu Feng" in the "Airs of Bei" is a matchless masterpiece in the history of Chinese literature, using taste to write of emotion. An abandoned wife uses the bitterness of the bitter herb (tu) to set off, by contrast, the bitterness within her own heart—the bitterness of the herb, compared to the bitterness in her heart, becomes, astonishingly, "as sweet as shepherd's purse." What a poignant contrast this is! The bitter herb is, in itself, bitter, yet because human life is even more bitter, it becomes, by comparison, "sweet"—herein lies a profoundly deep recognition of the bitterness of human existence.

This literary tradition of "writing bitterness through bitterness, savoring flavor within bitterness" continues on from the Book of Songs, becoming a profound recurring motif of Chinese poetry. That "the bitter herbs flourish" at Xiaoman places this image of "bitterness" at the very season when all things are approaching fullness constitutes a profound tension—the outer world is all "approaching fullness" and flourishing (the wheat waves lush and luxuriant), yet in a corner of that flourishing grows the "bitter herb," reminding people of the bitterness within fullness, the hardship behind the harvest. This juxtaposition of "fullness" and "bitterness" is precisely the complex, profound flavor of human life that Chinese literature excels at expressing—joy holding sorrow within it, sweetness holding bitterness, fullness holding incompleteness.

III. The Fragrant Herbs of the Verses of Chu and the Beauty of Southern Summer

Moving from the Book of Songs to the Verses of Chu (Chuci), the sense of summer in literature gains a further layer of magnificence and depth.

The south (correlated with Fire, with summer), as depicted by Qu Yuan, is a world of luxuriant fragrant herbs, brimming with vitality. The world of fragrant herbs in the "Li Sao"—gathering river selinea and angelica, stringing autumn orchids to wear as a girdle; plucking magnolia on the slopes at dawn, gathering evergreen grass on the islet at dusk—is precisely a portrait of the lush flourishing of plants and trees in the southern summer. The "Nine Songs," in "The Lady of the Xiang," has the line "gathering the sweet flag on the sandy isle, to send to one far away," and "The Mountain Spirit" has the lines "clad in creeping fig, girdled with dodder vine" and "the person of the mountains, fragrant with sweet flag, drinking from the stone spring, sheltered by pine and cypress"—what pervades these lines is precisely that beauty of "fullness" found in the southern summer's luxuriant plants and fragrant abundance.

But the depth of the Verses of Chu lies in this: within this world of "fullness," this world of fragrant herbs, it is suffused, from beginning to end, with a profound anxiety and searching. Qu Yuan is not intoxicated with self-satisfaction at the beauty of the fragrant herbs; rather, amid this beauty, he feels all the more keenly "the fear that the fair one's beauty will fade with age"—an anxiety over the fleeting nature of beauty (fullness). "Only I fear that the plants and trees will wither and fall, and that the fair one's beauty will fade with age" ("Li Sao")—plants and trees will inevitably wither, just as the fair one's beauty will inevitably fade, just as fullness will inevitably turn to emptiness. This sober-minded clarity, "anxious over the coming passing even amid fullness," resonates so profoundly with the spirit of "Xiaoman"—"flourishing yet knowing to guard against excess, full yet contemplating emptiness"! Qu Yuan's anxiety over the withering of plants and trees at their very height of flourishing is precisely like our ancestors' guarding against "great fullness" at the very season when all things approach fullness (Xiaoman)—both are the most sensitive, most profound recognition of the Dao of Heaven's principle that "fullness at its extreme must decline."

IV. "Blank Space" in Literature and the Aesthetics of "Xiaoman"

Finally, let us look, from a more panoramic angle, at how the spirit of "Xiaoman"—"full yet not overflowing, leaving room to spare"—has profoundly shaped the aesthetic character of Chinese literature.

What Chinese literature (poetry especially) has always prized most is never speaking every word to its very end or writing every feeling to its very full, but rather "words that end while meaning remains inexhaustible"—blank space, restraint, lingering resonance. Sikong Tu's Twenty-Four Categories of Poetry (though a work of the late Tang, its principles trace back to the pre-Qin thought of Zhuangzi and Laozi), discussing "restraint" (含蓄), says: "Without setting down a single word, the whole of its elegance is captured" (不著一字，尽得风流)—without stating it directly, and yet expressing the whole of its grace and spirit. This "blank space" of "not setting down a single word" is precisely the literary version of "Xiaoman"—not "filling" the meaning to the brim, but leaving vast blank spaces, letting the reader imagine, fill in, and savor.

Why does Chinese literature prize restraint and blank space so highly$10 Because a work that is "written full" (great fullness) has no lingering resonance—everything has been said, the reader need not, and indeed cannot, imagine anything further, and the work's vitality ends right there ("its function has failed"). A work of "restraint" (small fullness), by contrast, has "its function never fail"—it retains inexhaustible room, letting generation after generation of readers continually discover new meaning within it. This is precisely the literary embodiment of "great accomplishment seems flawed, yet its function never fails."

Tao Yuanming's line "in this there is a true meaning, but wishing to express it, I have already forgotten the words" ("Drinking Wine"), and Wang Wei's line "I walk to where the water ends, and sit to watch the clouds rise"—these timeless lines move us precisely because they both pause at the state of "Xiaoman": the meaning has already become full (a true meaning present, a subtle realm attained), yet remains restrained, unwilling to say it all (forgetting the words, sitting to watch), leaving an inexhaustible resonance for the reader to steep in. It may be said that the highest realm of Chinese literature is precisely the realm of "Xiaoman"—abundant yet not overflowing, restrained yet resonant, its words ending while its meaning remains inexhaustible.

Chapter 16 · Ancient Myth: The Cosmic Narrative of Fullness and Collapse

I. Gong Gong Furiously Butts Mount Buzhou: The Cosmic Archetype of Collapse at Fullness's Extreme

Among the myths of high antiquity, there is a narrative rich with the meaning of "collapse at fullness's extreme"—Gong Gong furiously butting his head against Mount Buzhou.

This myth appears in the "Treatise on Astronomy" (Tianwen Xun) of the Huainanzi and other texts: "In ancient times, Gong Gong and Zhuanxu contended to be sovereign. In his fury, Gong Gong butted against Mount Buzhou; the pillar of Heaven snapped, and the cord of Earth broke. Heaven tilted toward the northwest, and so the sun, moon, and stars shifted in that direction; Earth sank short in the southeast, and so the waters and floods, dust and silt, gathered there" (昔者共工与颛顼争为帝，怒而触不周之山，天柱折，地维绝。天倾西北，故日月星辰移焉；地不满东南，故水潦尘埃归焉). Gong Gong and Zhuanxu contended for the throne, and in his fury, Gong Gong butted against Mount Buzhou; as a result, the pillar supporting Heaven snapped, and the cord binding Earth broke as well. Heaven tilted toward the northwest, and so the sun, moon, and stars all shifted in that direction; Earth sank, falling short in the southeast, and so rivers, floodwaters, dust, and silt all flowed in that direction.

Note the deeply meaningful detail within this myth—"Earth sank short in the southeast" (地不满东南). After this cataclysmic upheaval, Heaven and Earth turned out to be "not full"—Heaven tilted in the northwest, Earth sank in the southeast, and the entire cosmos took on a configuration of "incompleteness, not full."

This myth of "Earth sinking short in the southeast" is precisely the cosmological archetype of the philosophy of "great accomplishment seems flawed," "small fullness with no great fullness"! In the imagination of our ancestors, even Heaven and Earth themselves were not "complete," but "not full" (incomplete). The sun, moon, and stars flow and shift because Heaven has tilted; the rivers and streams flow eastward because Earth has sunk—it is precisely this "not-fullness" (incompleteness) that gives rise to the flow, change, and ceaseless generation of the myriad things in the cosmos. Were Heaven and Earth absolutely "complete" (great fullness), this would instead be lifeless, stagnant, devoid of vitality. Only through "not-fullness" (an incompleteness resembling small fullness) does flow arise, does change arise, does this ceaselessly generating great world arise.

This resonates to the utmost degree with the Laozi's "great accomplishment seems flawed, yet its function never fails"—Heaven and Earth, this greatest of all "accomplishments," is precisely "as if flawed" (not full in the southeast), and it is precisely because of this "flaw" that its "function never fails" (the sun and moon ever turning, the rivers ever flowing, never ceasing). The myth of Gong Gong butting the mountain, in a tragic and magnificent manner, provides a soul-stirring cosmogonic narrative for the philosophy of "small fullness with no great fullness."

II. Nüwa Mends the Sky: Rebuilding Amid Incompleteness, Without Seeking Perfection

Connected to the myth of Gong Gong butting the mountain is the myth of Nüwa mending the sky. The "Treatise on Surveying the Obscure" (Lanming Xun) of the Huainanzi records: "In ancient times, the four pillars of Heaven collapsed, and the nine provinces split apart; Heaven could not entirely cover the earth, and Earth could not entirely support Heaven... Thereupon Nüwa smelted stones of the five colors to mend the azure sky, and cut off the legs of a giant turtle to set up the four pillars... The azure sky was mended, and the four pillars were set right..." (往古之时，四极废，九州裂，天不兼覆，地不周载……于是女娲炼五色石以补苍天，断鳌足以立四极……苍天补，四极正……). In ancient times, Heaven and Earth collapsed into ruin; Nüwa smelted stones of the five colors to mend the sky, and severed the legs of a giant turtle to re-erect the four pillars, at last mending the azure sky and setting the four pillars right once more.

Nüwa's mending of the sky was a reconstruction of cosmic order, following the "incompleteness" (Heaven tilted, Earth sunk) caused by Gong Gong. But what is most fascinating is this—after Nüwa mended the sky, Heaven and Earth were restored to basic order (the sky mended, the four pillars set right), yet were not restored to that state of absolute "completeness." The configuration of "Earth sinking short in the southeast" still remained, and the rivers still flowed eastward. What Nüwa accomplished was repair (making Heaven and Earth once again functional), not "filling to the brim" (making Heaven and Earth absolutely complete).

This, too, is a profound metaphor. Nüwa's wisdom (which is also the wisdom of our ancestors) lies in this: she repaired the collapse, yet preserved that "not-fullness" (incompleteness). She did not force Heaven and Earth into an absolute completeness, but accepted and preserved the configuration of "Earth sinking short in the southeast"—because she (our ancestors) understood well that it was precisely this "not-fullness" that was the very foundation on which Heaven and Earth could function, and all things could live and multiply. A Heaven and Earth "mended" into absolute completeness (great fullness) would, instead, lose its flow and vitality.

The myth of Nüwa mending the sky can therefore be read as yet another parable of the wisdom of "Xiaoman"—it tells us: in the face of incompleteness, one should repair it (making it functional), but need not, and should not, force it into absolute completeness (great fullness). To preserve a measure of "not-fullness" is, precisely, the highest wisdom. This resonates deeply with the Chinese spirit of "not seeking perfection, but seeking sufficiency, leaving room to spare."

III. Hou Yi Shoots Down the Suns: Restraining Excess, Returning to Balance

We have already touched, in discussing Lixia, on the myth of Hou Yi shooting down the suns. Here we shall elaborate further, from the angle of "restraining excess, guarding against great fullness," because this myth is especially crucial to understanding the spirit of "Xiaoman"—guarding against fullness.

The "Fundamental Warp" (Ben Jing Xun) of the Huainanzi records: "In the time of Yao, ten suns rose together, scorching the grain crops, killing the plants and trees, so that the people had nothing to eat... Yao therefore sent Yi... to shoot down the suns above" (逮至尧之时，十日并出，焦禾稼，杀草木，而民无所食……尧乃使羿……上射十日). In the time of Yao, ten suns rose together in the sky, scorching the crops and killing the plants and trees, leaving the people with nothing to eat... Yao therefore sent Hou Yi to shoot down the suns. Hou Yi shot down nine of the suns, leaving only one, and Heaven and Earth were restored to normal.

The core of this myth is precisely "restraining excess." Ten suns rising together represents the power of "Fire" (yang, the sun) flourishing to its very extreme (great fullness)—and the result of this "great fullness" is not abundance, but destruction (scorching the crops, killing the plants and trees). Hou Yi shooting down the suns, shooting down nine of them, is precisely restraining that "excessive" (great fullness) fiery force back to a "proper" (small fullness) degree—a single sun, just sufficient to warm the earth and nourish all things, without incinerating everything.

Consider carefully the relationship between this myth and "Xiaoman." Ten suns rising together (great fullness) → the destruction of everything; a single sun shining alone (small fullness) → the nourishment of all things. The very same "Fire" (the sun)—flourishing to "great fullness" (ten suns) brings calamity, while returning to "small fullness" (one sun) brings blessing. Is this not the most soul-stirring mythological demonstration of "small fullness with no great fullness"$11 Through the story of Hou Yi shooting down the suns, our ancestors proclaimed to the entire civilization an iron law—any force (even the fire of the sun that grants life itself), once it becomes "greatly full" (excessive), turns from blessing into calamity; only by restraining its excess and returning it to "small fullness" (moderation) can it fulfill its function of nourishing all things.

The wisdom embodied in Hou Yi shooting down the suns—"restraining excess, returning to balance"—is the same wisdom of the Dao of Heaven expressed differently through the Confucian "grasping the two extremes and applying the mean," the Daoist "knowing when to stop brings no danger," the Book of Changes' "the arrogant dragon has cause for regret," and, indeed, the very naming choice of "small fullness with no great fullness." With a single divine arrow, our ancestors shot down nine "excessive" suns, and, in doing so, also shot forth an entire civilization's eternal conviction—guarding against fullness, prizing the mean, esteeming harmony.

IV. The Revelation of Myth: The Cosmos, in Its Essence, Is "Not Full," and Thereby Ceaselessly Generative

Surveying together these three myths of high antiquity—Gong Gong butting the mountain, Nüwa mending the sky, and Hou Yi shooting down the suns—we can distill a profound conviction running through all three: the cosmos, in its essence, is "not full," and it is precisely this "not-fullness" that accomplishes ceaseless generation.

Gong Gong's butting of the mountain brought about "Earth sinking short in the southeast"—and thus Heaven and Earth gained flow (the sun and moon turning, the rivers flowing east). Nüwa's mending of the sky repaired the collapse while preserving "not-fullness"—and thus Heaven and Earth were able to function while remaining full of vitality. Hou Yi's shooting down of the suns restrained the "excessive" (great fullness) sun—and thus all things were able to flourish and multiply beneath a sun of "proper measure" (small fullness).

These three myths, from three different angles, jointly proclaim one and the same Dao of Heaven—absolute "completeness" (great fullness) is dangerous, destructive, and lifeless; while "not-fullness" (an incompleteness and moderation resembling small fullness) is the very root of vitality, flow, and ceaseless generation.

This is precisely the deepest cosmological foundation of "small fullness with no great fullness." Why did our ancestors alone refrain from establishing a "great fullness"$12 Because, in their mythological cosmos, "great fullness" (the excess of ten suns rising together, the lifelessness of absolute completeness) was never a state worth pursuing, but a calamity to be guarded against, restrained, and avoided. That our ancestors let all things pause at "small fullness," letting Heaven and Earth remain "not full," was precisely an accordance with this fundamental cosmic law that "only through not-fullness can there be ceaseless generation." That a civilization should quietly seal so profound a cosmic insight within the name of a single solar term is a cultural creation of the most remarkable lightness of touch, and of the most profound and expansive depth!

Chapter 17 · Musical Pitch: The Pitch-Pipe Zhonglü—The Musical Dao of Fullness That Can Still Be Empty

I. The First Month of Summer's Pitch Corresponds to Zhonglü

The "Monthly Ordinances" of the Book of Rites records that, in the first month of summer, "the pitch corresponds to Zhonglü" (律中仲吕, also written Zhonglü 中吕). Xiaoman falls within the first month of summer, and so its pitch corresponds to Zhonglü.

Ancient China possessed a system of "twelve pitch-pipes" (十二律)—Huangzhong, Dalü, Taicu, Jiazhong, Guxian, Zhonglü, Ruibin, Linzhong, Yize, Nanlü, Wuyi, and Yingzhong. These twelve pitches correlate with the twelve months, embodying our ancestors' profound thought of "the unity of pitch and calendar"—the rise and fall of musical pitch and the succession of the seasons, the waxing and waning of yin and yang, are different manifestations of one and the same cosmic rhythm.

The correspondence between the twelve pitches and the twelve months runs as follows: the eleventh month, mid-winter, corresponds to Huangzhong; the twelfth month, late winter, to Dalü; the first month, early spring, to Taicu; the second month, mid-spring, to Jiazhong; the third month, late spring, to Guxian; the fourth month, early summer, to Zhonglü; the fifth month, mid-summer, to Ruibin; the sixth month, late summer, to Linzhong... Zhonglü corresponds precisely to the fourth month, the first month of summer—the very month in which Xiaoman falls.

II. The Significance of the Name "Zhonglü": Yin Pitches Nearing Their End, Yang's Extreme Approaching

To understand the correspondence between Zhonglü and Xiaoman, we must first clarify the distinction, within the twelve pitches, between the "pitches" proper (律) and the "pitch-pipes" (吕).

The twelve pitches are divided into the "six lü" (六律, yang pitches) and the "six lü" in the other sense (六吕, yin pitch-pipes)—in English we may distinguish them as the "six yang pitches" and the "six yin pitch-pipes." The six yang pitches are Huangzhong, Taicu, Guxian, Ruibin, Yize, and Wuyi, belonging to yang; the six yin pitch-pipes are Dalü, Jiazhong, Zhonglü, Linzhong, Nanlü, and Yingzhong, belonging to yin. The yang pitches and yin pitch-pipes alternate, with odd-numbered months corresponding to yang pitches and even-numbered months to yin pitch-pipes.

Zhonglü is a member of the six yin pitch-pipes, situated within the sequence of yin pitch-pipes. But what is most fascinating is this—although Zhonglü belongs to the yin "pitch-pipes," the fourth month, the first month of summer, to which it corresponds, is precisely the month of yang qi at its most flourishing (hexagram Qian, six yang lines, pure yang)! This creates a profound tension: in the month of yang qi's greatest flourishing (the fourth month), the corresponding pitch is, of all things, the yin Zhonglü.

This tension conceals, precisely, the hidden mechanism of "the transition between fullness and emptiness." According to the principles set out in the "Treatise on Pitch-Pipes" (Lüshu) of the Records of the Grand Historian (Shiji) and the "Treatise on Pitch-Pipes and the Calendar" (Lüli Zhi) of the Book of Han (Hanshu), Zhonglü stands at the juncture where the yin pitch-pipes are nearly exhausted, on the verge of giving way, in the following month, to Ruibin (a yang pitch, corresponding to mid-summer, the fifth month, and to hexagram Gou, in which a single yin line is born). It is the last, faintest remaining trace of yin qi within a month of yang's flourishing—yin qi is here nearly exhausted, while yang qi is here approaching its utmost extreme. The character zhong (仲, "middle") in "Zhonglü" points precisely to its position at the midpoint, the turning point, of the waxing and waning of yin and yang.

How profoundly this accords with the spirit of "Xiaoman"! Xiaoman is the threshold at which yang qi is "full and flourishing, approaching its extreme" but has not yet triggered "the birth of yin"; Zhonglü is the juncture at which yin qi is "declining, nearly exhausted," about to yield to the extreme of yang. Both stand upon the eve of the transition between fullness and emptiness—one from the angle of "fullness" (yang approaching its extreme), the other from the angle of "emptiness" (yin nearing exhaustion), together marking that subtle moment of "about to turn but not yet turned." Musical pitch and the solar term, at this threshold of "about to turn but not yet turned," sound out one and the same mysterious note of the waxing and waning of fullness and emptiness.

III. The "Harmony" of Music and "Full Yet Not Overflowing"

The fundamental spirit of musical pitch lies in a single character—"harmony" (和). And the mystery of "harmony" lies, precisely, in "not-fullness," in "leaving room to spare."

The "Record of Music" (Yueji) chapter of the Book of Rites states: "Music is the harmony of Heaven and Earth... Because of harmony, the hundred things are all transformed and grow" (乐者，天地之和也……和故百物皆化). It also states: "The greatest music shares its harmony with Heaven and Earth" (大乐与天地同和)—the greatest music is as harmonious as Heaven and Earth itself.

What is the "harmony" of music$13 "Harmony" is not the infinite amplification of a single note (that would be noise, "fullness"), but the proper coordination, mutual restraint, and room to spare among many different notes. If a piece of music sounded every note at its loudest extreme (fullness), it would not be music at all, but noise; only through modulation, rising and falling, tempo and pause, and blank space left unfilled (not-fullness) can it become "harmony," can it become "music."

The Analects, "Ba Yi," records Confucius's discussion of the music of the "Guanju" ode: "Joyful, yet not excessive; sorrowful, yet not injurious" (乐而不淫，哀而不伤)—joyful, yet not carried to excess; sorrowful, yet not causing harm. This "not excessive," "not injurious," is precisely the embodiment, in music, of "full yet not overflowing"—joy (fullness) tempered by restraint (not overflowing), sorrow (fullness) tempered by proper measure (not overflowing). Emotion, in music, is given full expression (fullness), yet always maintains the proper measure of "central harmony" (not overflowing). A piece of music that is "joyful yet not excessive, sorrowful yet not injurious" is the perfect musical presentation of the realm of "Xiaoman"—emotion abundant yet not overflowing, expression full yet restrained.

IV. "The Greatest Music Has the Faintest Notes": The Highest Music Is "Not Full"

Chapter 41 of the Laozi contains a startling line: "The greatest music has the faintest notes" (大音希声)—the greatest, most perfect music is, instead, one whose sound can scarcely be heard (xisheng, "rare sound").

This is the Daoist school's most profound insight regarding music (and, by extension, regarding "fullness"). Why does "the greatest music" have, instead, "the faintest notes"$14 Because any specific, audible sound (fullness) is limited, partial—to play this note is to not play that one; to emphasize this key is to obscure that one. Only "the faintest notes" (a state approaching silence, retaining infinite blank space) can encompass every possible sound, and thus constitute truly "great," truly complete music.

"The greatest music has the faintest notes" is precisely the musical version of "great accomplishment seems flawed" and "great fullness seems empty." The most complete music (the greatest music), instead, presents itself as "faintest notes" (as if flawed, as if empty, not full). This is the very same wisdom as "small fullness with no great fullness"—the highest state is not "fullness" (the utmost of specific, audible sound), but "not-fullness" (the infinite potential contained within "the faintest notes").

From the pitch Zhonglü, to the harmony of "joyful yet not excessive," to the subtlety of "the greatest music has the faintest notes," we can see that the Chinese Dao of musical pitch is imbued, from beginning to end, with the spirit of "full yet not overflowing, full yet able to remain empty." Music is beautiful, is "harmonious," has "its function never fail," precisely because it never "plays to fullness," but always retains blank space, retains room to spare, retains that infinite possibility contained within "the faintest notes." The pitch-pipe Zhonglü, to which Xiaoman corresponds—as the mysterious note sounding at the juncture of yin and yang's transition—embodies most deeply, precisely, this musical Dao of "fullness that can still be empty, fullness that still leaves a margin." At the very moment yang qi approaches its extreme, it leaves behind, in one faint remaining strand of the nearly exhausted yin pitch-pipe, a lingering resonance of "not-fullness"—a resonance of turning and continuance, ceaselessly generative, for that full and flourishing Heaven and Earth.

Chapter 18 · The Ultimate Inquiry: Why Does Chinese Civilization Alone Cherish "Xiaoman"$15

I. Why Guard Against "Fullness"$16—The General Principle of the Dao of Heaven's Waxing and Waning

Having come this far, we have already touched, repeatedly, from the dimensions of etymology, astronomy, phenology, philosophy, myth, ritual institutions, and musical pitch, upon the central theme of "guarding against fullness, prizing modesty." Let us now pose, and answer, once and for all, the core question running through this entire essay—why does Chinese civilization guard against "fullness" so warily$17

The most fundamental answer lies in a general principle running through Heaven, Earth, and humanity alike—the waxing and waning of fullness and emptiness.

The Book of Changes, hexagram Feng, "Commentary on the Judgment"—"when the sun reaches its zenith, it begins to decline; when the moon reaches fullness, it begins to wane; the fullness and emptiness of Heaven and Earth wax and wane with the times"—is the most concentrated expression of this general principle. In the cosmology of our Chinese ancestors, the whole of Heaven and Earth was an eternally revolving system of the waxing and waning of fullness and emptiness—nothing can remain "full" forever; whatever is full must become empty, whatever is complete must become deficient, whatever flourishes to its utmost must decline. This is an iron law that bends to no human will.

In such a cosmos, why is "fullness" fearsome$18 Because "fullness" is the very summit of "brimming," and the summit of brimming is the starting point of emptiness. The sun at noon (fullness) must tilt; the full moon (fullness) must be eclipsed; the arrogant dragon (fullness) must have cause for regret; the tilting vessel filled to the brim (fullness) must overturn. "Fullness" means that one has already reached the very end of the ascending channel, and what follows can only be a fall. Thus, the wariness toward "fullness" is, at its root, a preemptive vigilance against that inevitable "decline," "deficiency," and "overturning" yet to come.

Once we understand this, we come to understand that deeply ingrained sense of "anxious foreboding" (忧患意识) within Chinese civilization. The "Great Treatise" (Xici Zhuan) of the Book of Changes asks: "Was it not perhaps with a sense of anxious foreboding that the author of the Changes composed this work$19" (作《易》者，其有忧患乎？)—was it not, perhaps, out of a profound sense of foreboding that the author of the Book of Changes composed it$20 This foreboding stems precisely from a deep insight into "the waxing and waning of fullness and emptiness"—precisely because one understands well that "fullness must inevitably lead to deficiency," one maintains, at the very moment when nothing has yet become "full," when there is still room to rise, a sober-minded vigilance, never letting oneself (or all things) slide toward that perilous "great fullness."

II. Why No "Great Fullness"$21—The Survival Wisdom of Seeking Completeness Through Incompleteness

A further inquiry: if "fullness" is to be guarded against, why not simply abolish "small fullness" as well$22 Why preserve "small fullness" specifically, while abolishing only "great fullness"$23

This is precisely the most exquisite, most dialectical point of Chinese wisdom.

Were there no "small fullness" either, and all things forever remained in a state of "not-fullness" (emptiness, deficiency, insufficiency), this too would be undesirable—the tilting vessel "tilts when empty" (unstable when empty); the mi grass, without the fullness of yang qi, could support no flourishing of life whatsoever; the wheat, without filling with grain (small fullness), would have no hope of harvest at all. Pure "not-fullness" (emptiness) is scarcity, stagnation, lifelessness—equally a violation of the Dao of Heaven.

The exquisiteness of Chinese wisdom lies precisely in this: between the two extremes of "fullness" (inevitable deficiency) and "not-fullness" (scarcity), it precisely singles out an optimal solution—"small fullness." "Small fullness" is the true, substantial abundance of "filling every hollow before advancing" (not scarcity), and also the room to spare of "great accomplishment seems flawed" (not great fullness). It enjoys the benefits of "fullness" (vitality, hope, abundance), while avoiding the dangers of "fullness" (decline following utmost flourishing, reversal at the extreme). It is the perfect balance of abundance and restraint, the wise unity of fullness and modest withdrawal.

This is precisely the survival wisdom of "seeking completeness through incompleteness"—preserving a touch of "incompleteness" (not reaching great fullness) is, precisely, in order to fulfill that "completeness" (a lasting, sustainable perfection). A thing that forever pauses at "small fullness" achieves, instead, the most enduring "completeness"—because it forever remains within the ascending channel, forever has room to continue growing, forever has "its function never fail." A thing that pursues "great fullness," though seemingly attaining "completeness," in fact slides immediately into "deficiency," and thereby loses "completeness" instead.

The Most High said: "The crooked becomes whole; the bent becomes straight; the hollow becomes full; the worn becomes new; having little, one gains; having much, one is bewildered" (曲则全，枉则直，洼则盈，敝则新，少则得，多则惑; Daodejing, Chapter 22). What is crooked can, instead, be preserved whole; what is bent can, instead, become straight; what is hollow can, instead, become full; what is worn can, instead, become new; taking little, one gains; craving much, one becomes bewildered. The three characters "the hollow becomes full" (洼则盈) strike especially close to the principle of "Xiaoman"—preserving hollowness (modesty, not-fullness) can, instead, achieve true fullness. "Having little, one gains; having much, one is bewildered"—being content with "small fullness" (little), one gains something instead; coveting "great fullness" (much), one falls, instead, into bewilderment and calamity. "Small fullness with no great fullness" is precisely the calendrical crystallization of this series of dialectical wisdoms—"the crooked becomes whole," "the hollow becomes full," "having little, one gains."

III. How Has "Xiaoman" Become the Spiritual Undertone of an Entire Civilization$1

The final inquiry is this: how has this wisdom of "full yet not overflowing, guarding against fullness, prizing modesty" become the spiritual undertone of the entire Chinese people, permeating every corner of our culture$2

The answer, perhaps, lies in the "universality" and "practicality" of this wisdom.

It is universal—from governing a state ("preserving fullness, guarding peace") to managing a household ("modesty receives gain"), from self-cultivation ("never satisfied in learning") to conducting oneself in the world ("leaving room to spare in all things"), from aesthetics ("blank space and restraint") to health cultivation ("diminishing rich flavors, letting the will know no anger")—the wisdom of "full yet not overflowing" applies everywhere. It is not specialized knowledge confined to any one field, but a fundamental attitude running through every field at once.

It is practical—it is not an abstract principle suspended in the void, but a wisdom of daily life that can be put into practice in every specific act. A Chinese person, upon achieving success, knows to withdraw modestly (not self-satisfied); upon seeing flowers half-open, knows to appreciate them (not seeking them fully bloomed); when speaking, knows to leave something unsaid (not saying everything); upon achieving fame and accomplishment, knows to step back (not clinging to it)—all of this is the natural expression, in the ethics of daily life, of the wisdom of "Xiaoman."

And what is most remarkable of all is that our ancestors found so ingenious a vessel to seal this vast and profound wisdom within—the name of a single solar term. "Xiaoman"—these two characters, arriving punctually before every Chinese person, year after year, with the turning of the calendar, silently remind us: it is enough for things to attain a small fullness; there is no need for great fullness; only by being full yet not overflowing can things endure. What a superior mode of cultural transmission this is! It relies on no sermonizing, no indoctrination, but instead, through the rhythm of Heaven and Earth's motion, through the cycle of a single solar term, transmits a civilization's most central wisdom, year after year, silently as the nourishing rain, to generation after generation of descendants.

When we gaze once more upon the two characters "Xiaoman" today, what we gaze upon is not merely a farming season, not merely a solar term, but a civilization's wisdom in facing fullness and emptiness, success and failure, the rise and fall of human life—a wisdom that, across several thousand years, has grown only more profound: full yet not overflowing, brimming yet able to remain empty, approaching fullness but not yet full, always leaving room to spare. This is "Xiaoman."

Conclusion · The Realm of Xiaoman: Settling Life Where Fullness Approaches but Has Not Yet Arrived

I. Looking Back: What Have We Understood About "Xiaoman"$3

Through the layered inquiries of the eighteen chapters above, we have explored, in depth, this singular solar term "Xiaoman," from the angles of etymology, astronomy, the calendar, phenology, myth, philosophy, governance, ethics, ritual institutions, literature, musical pitch, and health cultivation.

We have come to understand: the original meaning of "fullness" (满) is "brimming to overflowing," a dangerous threshold standing at the very edge of "overflow"; and the "small attainment of fullness" (小得盈满) of "Xiaoman" is precisely our ancestors' wise pause before this threshold—abundant, yet not overflowing; approaching fullness, yet leaving room to spare.

We have come to understand: that the twenty-four solar terms include "small fullness" but alone lack "great fullness" is by no means an oversight, but the most profound choice of Chinese civilization—it embodies a civilization's core values of "guarding against fullness, prizing modesty, full yet not overflowing," crystallizing, within the name of a single solar term, the entire wisdom of the Book of Documents' "fullness invites loss, modesty receives gain," the Laozi's "to hold a vessel and fill it to the brim is not as good as stopping in time," the Book of Changes' "the arrogant dragon has cause for regret," and hexagram Qian's "the Way of Heaven diminishes fullness and augments modesty."

We have come to understand: that Xiaoman's three pentads—the bitter herbs flourish (sweetness gestating within bitterness), the mi grass dies (loss lurking within fullness), and wheat's autumn arrives (approaching ripeness but not yet ripe)—jointly set off, from the three dimensions of taste, of life and death, and of time, the profound mood of "Xiaoman": approaching fullness but not yet full, flourishing yet knowing to guard against excess; and that "wheat's autumn arrives" further reveals the hidden mystery that "autumn" originally meant "ripening," and that time possesses relativity.

We have also come to understand: the Confucian "fullness invites loss," the tilting vessel's "fullness brings overturning," the Doctrine of the Mean's "the mean brings uprightness"; the Daoist "knowing contentment brings no disgrace, knowing when to stop brings no danger," "great accomplishment seems flawed," "accomplishing one's task and then withdrawing"; hexagram Qian's "the arrogant dragon has cause for regret" and "a flock of dragons without a head"; and even the myths of Gong Gong butting the mountain, Nüwa mending the sky, and Hou Yi shooting down the suns—all of these distillations of pre-Qin wisdom have, it turns out, found their common destination and most concentrated expression within this single solar term, "Xiaoman."

II. The Realm of Xiaoman: A Metaphor

If we liken human life to a year of farm work, then each of us is pursuing our own "harvest"—success in our career, refinement in our learning, completeness in our family, fulfillment in our life.

And "Xiaoman" tells us: the most beautiful state of human life may not be that summit of "great fullness" (utter completeness), but rather the midst of this "small fullness" (approaching fullness but not yet full)—the wheat kernels filling with grain, the harvest already in sight, the future bright yet still leaving room to spare; everything still growing, everything still holding possibility, nothing yet having reached that turning point where "flourishing at its utmost turns to decline."

The realm of "Xiaoman" is a realm of "being on the way"—it does not seek to arrive at the destination (great fullness), because after the destination there is only decline; what it cherishes is the process of "being in the midst of becoming complete"—within this process, hope always lies ahead, vitality is always surging forth, and life's "function never fails."

What a lucid and yet positive wisdom of life this is! It is not a passive "contentment" (stagnation, no further progress), but an active "leaving room to spare" (forever advancing without overreaching); it is not a mediocre "moderation" (inaction), but a wise "preserving of fullness" (guarding that enduring quality even amid fullness). "Xiaoman" teaches us: strive vigorously to fill ourselves (do not remain empty), yet modestly leave room to spare (do not become self-satisfied); walk toward completeness filled with hope (do not be passive), yet remain soberly free of covetousness for that perilous utmost fullness (do not become the arrogant dragon).

III. A Final Inquiry: In This Age That Exalts "Great Fullness," Why Do We Need "Xiaoman" All the More$4

At the close of this essay, let us return to the present moment, and pose one final inquiry.

We live in an age that exalts "great fullness"—pursuing the maximization of profit, the utmost extreme of efficiency, the infinite satisfaction of desire. "More, faster, bigger, fuller" has become the implicit creed of this age. We are taught never to be content, to expand ceaselessly, to pursue that seemingly infinite "great fullness."

And yet, has this age that exalts "great fullness" truly made us happier, more at peace, more enduring$5 Or are we, instead, like that person "holding a vessel and filling it to the brim," like that dragon flying toward "overreaching," like that tilting vessel about to overturn once filled to the brim—drawing ever closer, in our endless pursuit of "great fullness," to that perilous cliff of "fullness brings overturning"$6

It is precisely in such an age that the ancient wisdom of "Xiaoman" appears all the more precious and urgent. It reminds us, gently yet firmly: it is enough for things to attain "small fullness"; there is no need for "great fullness"; filling to the point of "small fullness" is best, for anything more becomes "overflow." It teaches us, in this age that encourages infinite expansion, to relearn how to "know when to stop"—to know where to pause, to know that "the hollow becomes full, having little, one gains," to know to "accomplish one's task and then withdraw," to know how to convert that perilous "great fullness" into a stable and enduring "small fullness."

To understand "Xiaoman" anew is not to ask us to abandon our pursuits and be content with mediocrity, but to ask us to recalibrate our understanding of "completeness"—true completeness lies not at that summit where flourishing at its utmost turns to decline (great fullness), but within that wisdom of "full yet not overflowing, leaving room to spare" (small fullness). A person who understands "Xiaoman" does not forget anxious foreboding even amid a bountiful harvest, maintains modest withdrawal even amid success, and leaves room to spare even amid fullness—and it is precisely such a person who attains the most enduring, the most composed, the least easily overturned "completeness" of all.

Every year, in late May, when "Xiaoman" arrives as promised, when the wheat waves grow lush across the fields, the bitter herb flowers bloom, and wheat's autumn draws near—may we all, within this Heaven and Earth of "approaching fullness but not yet full," come to understand our ancestors' profound wisdom, and settle within ourselves a heart that both longs to be filled, and yet knows to withdraw modestly and preserve incompleteness.

The Book of Documents says: "Fullness invites loss, modesty receives gain—this is the Way of Heaven."

Such is the Way of Heaven. So too is the wheat ear—the fuller it grows, the lower it bows its head.

And we—have we understood$7
