A Clap of Spring Thunder: The Awakening of Life and the Way of Dormancy in the Jingzhe Solar Term

Introduction: Why Should We Listen Anew to This Clap of Spring Thunder$1

Between heaven and earth, all things have their season. Among the Twenty-Four Solar Terms, Jingzhe (Awakening of Insects) is the most dramatically charged. It does not open quietly like Lichun (Beginning of Spring), nor does it mark itself by the extremity of the sun's shadow like Xiazhi (Summer Solstice). Jingzhe is a solar term named after sound -- it is by a resounding clap of spring thunder that the earth, slumbering through the whole of winter, is roused awake.

Why did the ancients establish a solar term specifically named after "startling" (jing)$2 Why, in their cosmology, did the awakening of all things not occur naturally but required being "startled," being "roused"$3 What, precisely, did that thunderclap set in motion$4 Did it awaken merely the insects hibernating in the soil, or some deeper, more universal life force$5

The Book of Documents (Shangshu, "Canon of Yao") states: "He thereupon commanded Xi and He, in reverent accordance with august Heaven, to calculate and delineate the sun, moon, and stars, and so respectfully to deliver the seasons to the people." These few words capture the fundamental reason for the birth of the solar terms -- "respectfully to deliver the seasons." The word "respectfully" (jing) and the word "deliver" (shou) elevate astronomical observation to an almost religious plane. Observing the heavens was not to satisfy curiosity but to express "reverence" -- awe before the Way of Heaven. Delivering the seasons was not for convenience but to "deliver" -- to transmit the will of Heaven to the human world. Among all the seasons that needed to be "delivered" to humankind, Jingzhe was the most critical: it marked the true beginning of the year's agricultural work, the transition of the earth from deathly stillness to vitality, the reactivation, after a winter's slumber, of that ancient bond between Heaven and humankind.

Why should we reexamine Jingzhe from the perspective of the pre-Qin era and high antiquity$6 Because that was the age in which this solar term was born -- an age when its meaning had not yet been obscured by layer upon layer of later commentary. In that age, thunder was not a meteorological phenomenon but the language of Heaven. The awakening of hibernating creatures was not a biological instinct but proof of the mutual responsiveness of Heaven and humanity. Jingzhe was not a mark on the calendar but a solemn cosmic ceremony -- Heaven, through its thunderous voice, issued a summons to all slumbering things, and all things answered that summons by awakening.

Embedded within this is a question of extraordinary depth: How do all things "know" that spring thunder has sounded and that they should awaken$7 A hibernating creature buried several feet underground can neither hear the thunder nor see the sunlight. By what means does it "know" that the season has turned and life should begin again$8 The ancients' meditation on this question touched upon the most subtle core of the cosmology of the unity of Heaven and humanity.

The Wenyan commentary on the Qian (Heaven) hexagram of the Book of Changes (Yijing) declares: "The great person is one whose virtue accords with that of heaven and earth, whose brilliance accords with that of the sun and moon, whose order accords with that of the four seasons, and whose sense of fortune and misfortune accords with that of the spirits and gods." To "accord with the order of the four seasons" means that a person's actions, emotions, and even states of mind should all undergo corresponding adjustments as the four seasons turn. Jingzhe is precisely that critical threshold where "storing" turns to "moving," where quiescent dormancy transforms into vigorous action. Across this threshold, what had lain dormant through the winter was not insects alone, but also the human spirit, human aspiration, and every dimension of human vitality.

This article will proceed from the core ideas of the two pre-Qin schools -- the Confucian and the Daoist -- while reaching back to still more ancient traditions of myth and etymology, to undertake as thorough a reading as possible of the Jingzhe solar term. We seek to know not only what Jingzhe is but why it is so; not only what the ancients did at Jingzhe but why they did it. We shall examine the tortuous history by which its original name "Qizhe" was changed to avoid the taboo name of Emperor Jing of the Han. We shall peer into the cosmic tableau behind the two characters "jing" and "zhe." We shall hearken to the ancient echo of "the sovereign emerges from Zhen" in the Zhen (Thunder) hexagram of the Book of Changes. In the course of these inquiries, perhaps we can once again touch that ancient world in which all things possessed spirit and Heaven and humanity responded to each other -- and in that clap of spring thunder, hear a summons addressed to our own lives.

Chapter One: "Jing" and "Zhe" -- The Realm Between Heaven and Humanity in Two Characters

I. Why Is "Zhe" the Character "Zhe"$9

Before entering into the specific discussion of Jingzhe, we must first contemplate the two characters that compose this solar term's name -- "jing" (startle) and "zhe" (hibernate). Why were these two characters chosen to name this node in mid-spring$10 What are their original meanings$11

Let us begin with "zhe." Xu Shen, in the Shuowen Jiezi (Explaining Graphs and Analyzing Characters), states plainly: "Zhe means to hide. From the radical 'insect' (chong); 'zhi' provides the phonetic." In this single brief sentence, the core meaning of "zhe" is made clear -- to lie concealed, to be hidden away. The character takes the radical for "insect," indicating that it was originally used to describe the behavior of insects: the state in which creatures burrow into the earth as cold winter approaches, lie concealed without emerging, and cease all activity. This is what we today call "hibernation."

Yet the significance of "zhe" extends far beyond the objective description of a biological phenomenon. In the minds of the ancients, "hiding" (cang) was a concept charged with philosophical meaning. Why must all things "hide"$12 Because the qi of heaven and earth in winter is contracting, sealing, turning inward. The Monthly Ordinances (Yueling) section of the Book of Rites (Liji) describes the first month of winter: "Water begins to freeze, the ground begins to harden... the qi of heaven ascends, the qi of earth descends; heaven and earth do not communicate, and so winter is formed by closure and blockage." When the qi of heaven and earth are mutually severed and blocked, that is the essence of "winter." In such an environment, if all things did not "hide," they could not survive. The "hiding" of hibernating creatures is a survival wisdom that accords with the Way of Heaven -- they are not fleeing but waiting; not sleeping but nourishing.

This leads us to a profoundly important connotation of the character "zhe": to hide is in order not to hide; to lie low is in order to rise up. A creature's dormancy underground through winter is not the cessation of life but another form of life -- a form that contracts inward, stores energy, and awaits the proper moment. The Xici commentary (Part II) of the Book of Changes offers a supremely incisive statement that serves as the finest explication of the philosophy of "zhe": "The inchworm bends in order to stretch; the dragon and the snake hibernate in order to preserve their lives" (chi huo zhi qu, yi qiu xin ye; long she zhi zhe, yi cun shen ye). The inchworm (a caterpillar that arches its back to crawl) bends its body so as to extend itself forward; the dragon and the snake hibernate precisely to preserve their lives. We shall devote a later chapter to discussing the "Way of bending and stretching" contained in this passage. Here, let us simply note: in the wisdom of the ancients, "zhe" was by no means passive retreat but a far-sighted, strategic contraction undertaken for the sake of a greater future rising.

II. Why Is "Jing" the Character "Jing"$13

Now let us examine "jing." The original meaning of "jing" is to startle, to shake, to rouse. It describes a sudden, violent change of state brought about by an external force -- something originally calm, still, or sleeping is abruptly awakened by some power.

In the name of this solar term, what is the "external force" to which "jing" refers$14 It is thunder. Spring thunder erupts, shaking heaven and earth with a resounding crash, startling the creatures hibernating underground into wakefulness -- this is the most direct, literal meaning of the two characters "Jingzhe." As the old verse has it: "A light rain freshens all the plants; a single thunderclap begins Jingzhe." It captures precisely this sense: one clap of spring thunder, and Jingzhe has begun.

Yet here lies a question worthy of deep reflection: Are the hibernating creatures truly "startled" awake by the sound of thunder$15

From the perspective of modern biology, the awakening of dormant creatures is primarily due to rising air and soil temperatures, and bears no direct causal relationship to thunder. In fact, creatures buried underground may not truly be able to "hear" thunder at all. Why, then, did the ancients use the character "jing" and attribute the awakening of dormant creatures to the shock of spring thunder$16

This is precisely where the cosmology of the ancients is most subtle and most worthy of our appreciation. In the ancients' view, thunder was not merely a sound; it was the most intense sign of yang qi breaking forth and bursting through the gloom. In winter, yang qi lies hidden beneath the earth (this is the original meaning of the Fu hexagram's "one yang returns"). As the seasons progress, the yang qi underground grows ever stronger, until at mid-spring it finally accumulates to a critical point and erupts through the constraints of the surface, manifesting as thunder. Thus, what awakens the dormant creatures is, on the surface, the sound of thunder, but in essence the surging yang qi that the thunder represents. What the creatures sense is not the sound waves traveling through the air but the holistic, all-pervading force of yang qi bursting forth between heaven and earth.

This is the deeper meaning of "jing": it is not a simple physical stimulus but a "summons" from Heaven to all slumbering things. Heaven uses thunder as its command, issuing the directive "It is time to awaken," and all things -- whether plants on the ground, birds in the air, or creatures beneath the earth -- simultaneously sense this force and awaken together. What "jing" describes is the critical instant when life transitions from quiescence to vigorous action, the sacred moment when the deathly still earth is infused anew with vitality.

III. "Jingzhe" Viewed as a Whole: An Awakening Between Heaven and Humanity

When we view "jing" and "zhe" together, we arrive at a vivid cosmic tableau: Heaven, using spring thunder as its signal (jing), rouses all things dormant beneath the earth (zhe), and life thus transitions from a state of "hiding" to one of "movement."

This very mode of naming embodies the ancients' profound understanding of life's movement: the awakening of life is not isolated or spontaneous but a matter of mutual response between Heaven and humanity, a penetrating communion between above and below. The dormant creature does not decide on its own to awaken; it is roused by Heaven. And Heaven rouses it because the qi of heaven and earth has arrived at the season when it should be roused. In this process of awakening, Heaven, earth, and the creature form a complete, mutually responsive organic system.

What is still more noteworthy is that the name "Jingzhe" emphasizes passivity -- the creature is "startled awake," not "awakened on its own." This is fundamentally different from the modern notion of "the alarm goes off and I get up." In the ancients' conception, the rhythm of life is not in the hands of the living being itself but in the hands of Heaven. Humans, as one among all things, are likewise subject to this. Human rest and work, human labor and effort, human states of mind and spirit -- all should adjust in accordance with the turning of the heavenly seasons. At Jingzhe, since Heaven has used thunder to rouse the dormant creatures, humans too should answer this summons -- emerging from their winter dormancy (the agricultural off-season, the time of recuperation) to begin the year's labor and effort.

This is the essence of the solar terms: they are not arbitrary human divisions but objective nodes in the operation of the Way of Heaven, and more than that, directives issued by Heaven to humankind. Jingzhe was established as a solar term not because some sage-king had a passing fancy but because the ancients, through long observation, discovered that at this point in the year, a holistic, irreversible transformation occurs between heaven and earth: yang qi breaks through the blockade of yin qi, and all things turn from "hiding" to "moving." The most powerful symbol of this transformation is that clap of thunder that rends the sky. By naming this solar term "Jingzhe," the ancients sought, in the most concentrated language possible, to capture this magnificent instant when life shifts from stillness to motion.

Chapter Two: "Qizhe" and "Jingzhe" -- A Historical Case of Taboo-Driven Renaming

I. Jingzhe Was Originally Named "Qizhe"

Before delving deeper into the meaning of Jingzhe, we must first clarify an important historical matter -- this solar term was originally called not "Jingzhe" but "Qizhe" (Opening of Hibernation).

This is no small matter. A change in a solar term's name implicates the ancient Chinese system of name taboos, the evolution of calendrical science, and the philosophical resonances behind written characters. To truly understand Jingzhe, one cannot avoid tracing its original name.

The evidence is conclusive. The Xia Xiao Zheng (Lesser Annuary of the Xia) -- an ancient text traditionally attributed to the Xia dynasty that records the phenology of all twelve months -- under its entry for the first month states: "In the first month: Qizhe." It uses the characters "Qizhe" unambiguously. The Zuo Zhuan (Commentary of Zuo), in the fifth year of Duke Huan, records: "For all sacrifices, the suburban sacrifice is held after Qizhe." Here again, "Qizhe" is the term used. Moreover, the Lushi Chunqiu (Spring and Autumn Annals of Master Lu), the Huainanzi, and other pre-Qin and Han texts all preserve traces of the name "Qizhe."

From this evidence, it is clear that before the Han dynasty, the original name of this solar term was "Qizhe" -- "qi" meaning to open, to initiate. "Qizhe" means: to open up those dormant lives, to release them from their state of concealment. What an elegant and precise name this is -- it emphasizes the action of "opening," the image of heaven and earth opening a door to release the dormant creatures of the world.

II. Why Was "Qi" Changed to "Jing"$17 Avoiding the Taboo Name of Emperor Jing of the Han

Why, then, did "Qizhe" become "Jingzhe"$18

The answer lies in the uniquely Chinese institution of "name taboos" (bihui). Name taboos required that in speech and writing, one must avoid using the personal name of the ruler or one's elders; to speak or write the name directly was a grave offense. This was the manifestation, in the realm of language, of the patriarchal hierarchy of ancient China.

Emperor Jing of the Han bore the name Liu Qi. The character "qi" was thus the reigning emperor's taboo name. Since "qi" had become the emperor's forbidden name, both popular and official usage could no longer freely employ this character. Accordingly, the "qi" in the solar term name "Qizhe" had to be replaced. With what$19 The ancients chose the near-synonym "jing" -- since "Qizhe" meant to open up the dormant creatures, to awaken them, "Jingzhe" -- to startle the dormant creatures, to shock them awake -- conveyed roughly the same meaning. And so "Qizhe" was changed to "Jingzhe."

This, then, is the fundamental reason for the renaming: avoiding the taboo name of Emperor Jing (Liu Qi) of the Han. This is a historical detail repeatedly verified by scholars and supported by ample documentary evidence. Understanding this point clarifies why a solar term that should have been called "Qizhe" is today called "Jingzhe."

It is worth noting that concurrent with the change from "Qizhe" to "Jingzhe," there was also an adjustment to the ordering of the solar terms. In the early solar term system before the Han dynasty, the position of "Qizhe" differed slightly from its later placement -- it once preceded "Yushui" (Rain Water). After adjustment, the familiar sequence of "Lichun -- Yushui -- Jingzhe -- Chunfen" took shape. Whether this reordering was exactly simultaneous with the renaming is still debated among scholars, but that "Qizhe" became "Jingzhe" due to name taboo avoidance is a well-established conclusion.

III. The Philosophical Import of a Single Character's Difference: From "Qi" to "Jing"

The taboo-driven renaming was an act of political necessity, yet intriguingly, the single-character difference between "qi" and "jing" inadvertently introduced a subtle shift in meaning that rewards careful contemplation.

"Qi" means to open. "Qizhe" emphasizes heaven and earth actively opening -- Heaven, like a benevolent sovereign, gently opens the door that has been closed for a whole winter, releasing the dormant lives within. There is a sense of composure, of gradual unfolding, of natural ripening -- as though a door-pivot slowly turns and the door-leaves gently swing open.

"Jing" means to shake, to alarm. "Jingzhe" emphasizes a sudden, violent shaking -- Heaven, with the force of ten thousand thunderbolts, abruptly jolts the earth, "frightening" or "shocking" the sleeping creatures awake. There is a sense of swiftness, intensity, and irresistibility -- like a crash of thunder that makes the heart leap.

This single-character difference happens to correspond to two different understandings of how life awakens. "Qi" emphasizes the naturalness and composure of the process, in a manner consonant with Daoist sensibility -- "the Way follows Nature," and all things are gently opened in accordance with their own rhythm. "Jing" emphasizes the intensity and grandeur of the force, with a more virile and assertive quality -- it stresses the unstoppable power of yang qi surging forth, the majesty of thunder rousing all things.

From this angle, though the taboo-driven renaming was fortuitous, it inadvertently strengthened the association between this solar term and "thunder." The character "jing" points directly to that clap of spring thunder, to the spectacular scene of yang qi erupting and shaking heaven and earth. And the philosophy of the Zhen (Thunder) hexagram and of thunder itself, which we shall discuss at length in later chapters, unfolds precisely around the theme of "shaking" that "jing" brings to the fore.

One might say that "Qizhe" is a gentle opening, while "Jingzhe" is a thunderous awakening. The two names record the same solar term, yet they also refract different facets of the ancients' understanding of the fundamental question "How does life awaken$20" History ultimately preserved for us the more powerful, more dramatic name -- Jingzhe.

IV. The Cultural Significance of Taboo-Driven Renaming: The Interweaving of Institution, Language, and Calendar

The renaming of Jingzhe through taboo avoidance was not an isolated case. In ancient China, the phenomenon of changing characters, names, and place-names to avoid taboo names was extremely widespread, constituting a distinctive cultural landscape. To fully understand the "Qizhe to Jingzhe" affair, we must situate it within the broader context of taboo culture.

The taboo system had its roots in patriarchal hierarchy and the veneration of names. The ancients believed that a name was not merely a label but was intimately connected to a person's essence and dignity. To call out the name of a ruler or elder directly was an affront. Therefore, any character identical to the taboo name of a ruler or elder had to be avoided -- either replaced with a synonym or near-synonym (as "qi" became "jing"), or replaced with a similarly pronounced character, or simply written with strokes omitted. The Han dynasty was a period when the taboo system became increasingly strict, and avoidance of imperial names was especially rigorous. Emperor Jing's name was Qi; therefore, all occurrences of the character "qi" throughout the realm had to be avoided, and even a solar term's name could not escape -- this was the institutional context for the change from "Qizhe" to "Jingzhe."

Similar examples abound. To avoid the taboo name of Emperor Wen of the Han (Liu Heng), "Mount Heng" was renamed "Mount Chang," and even the mythological figure Heng'e was altered to "Chang'e." To avoid Emperor Wu of the Han (Liu Che), "Kuai Che" was renamed "Kuai Tong." Clearly, name taboo was a force powerful enough to reshape language, place-names, personal names, and even the texts of the classics. The change from "Qizhe" to "Jingzhe" is a vivid mark left by that force upon the names of the solar terms.

The lesson of this affair runs deep: many of the words and names we use today conceal tortuous histories behind them. A name that seems perfectly natural -- "Jingzhe" -- is in fact the product of a political institution (name taboo) acting upon astronomical calendrical science (the solar terms). Had Emperor Jing of the Han not been named Liu Qi, had there been no taboo institution, we might today still be using that more elegantly archaic name -- "Qizhe." Through the evolution from "Qizhe" to "Jingzhe," we see not merely the transformation of a solar term's name but a vivid microcosm of how politics, language, calendar, and culture in ancient China intertwined and mutually shaped one another. And whether called "Qizhe" or "Jingzhe," the celestial node that this solar term marks -- mid-spring, the surging of yang qi, the awakening of dormant creatures -- remains unchanged through the ages. The name may be altered, but the Way of Heaven endures.

Chapter Three: The Astronomical Foundation of Jingzhe -- The Sun Reaches 345 Degrees of Celestial Longitude

I. 345 Degrees Celestial Longitude: The Astronomical Position of Jingzhe

From the perspective of modern astronomy, the determination of Jingzhe has a precise standard: when the sun reaches 345 degrees of ecliptic longitude, it is Jingzhe.

What is ecliptic longitude$21 It is the longitude in the ecliptic coordinate system. The ecliptic is the apparent path traced by the sun across the celestial sphere over the course of a year, as seen from earth. Although the ancients did not know that the earth revolves around the sun, through long observation they accurately grasped the sun's annual cycle against the backdrop of the fixed stars and divided this path into 360 degrees. Taking the vernal equinox as zero degrees of ecliptic longitude, each 15-degree increment corresponds to one solar term. Thus the twenty-four solar terms evenly divide one complete circuit of the ecliptic (360 degrees).

In this system: the Vernal Equinox (Chunfen) is at zero degrees, Qingming at 15 degrees, Guyu at 30 degrees, and so forth. Jingzhe corresponds to 345 degrees -- that is, 15 degrees before the Vernal Equinox (360 degrees, i.e., the next zero). In other words, after Jingzhe, the sun travels another 15 degrees before reaching the equinoctial point. This precisely positions Jingzhe in mid-spring, just before the equinox.

It should be specially noted that pre-Qin peoples of course did not possess the precise concept of "345 degrees ecliptic longitude." The method of defining solar terms by the sun's ecliptic degree is a product of later refinement in astronomical calendrical science. However, the astronomical reality underlying this precise degree -- that the sun has progressed to mid-spring, that day and night are about to be equal, that yang qi is daily growing stronger -- was grasped by the ancients long ago through their own methods (shadow observations, stellar observations, phenological verification). The modern "345 degrees ecliptic longitude" merely restates, in more precise mathematical language, the celestial node that the ancients had already discerned.

II. Shadows and the Gnomon: How the Ancients Determined the Seasons

How did the ancients determine the specific dates of solar terms such as Jingzhe$22 The most fundamental method was the observation of shadows.

The Rites of Zhou (Zhouli), in the section on the Grand Minister of Education, records: "Using the method of the gnomon to measure the depth of the earth, to correct the sun's shadow, and thereby to find the center of the land." The gnomon (guibiao) was one of China's most ancient astronomical instruments. A vertical pole (the "biao") plus a horizontal measuring rod (the "gui") formed a complete system for astronomical observation. By measuring the length of the pole's shadow at noon, the ancients could precisely determine the sun's altitude in the sky and thereby fix the solar terms.

The higher the sun, the shorter the noon shadow; the lower the sun, the longer the noon shadow. At the winter solstice the sun is lowest and the shadow longest; at the summer solstice the sun is highest and the shadow shortest. Jingzhe falls between the solstices, near the equinox, and its shadow length lies between the two extremes -- and is shortening day by day. This signifies that the sun is rising day by day, daylight is lengthening, and yang qi is strengthening. Through years and decades of observing and recording the shadow cast by the gnomon, the ancients gradually mastered the laws governing shadow changes and were able to predict the arrival of each solar term with precision.

Here arises a question worthy of reflection: How did the ancients first conceive the idea of measuring shadows$23 The change in shadow length is exceedingly gradual, with only the slightest daily difference. What keenness and patience drove the ancients to undertake this observation spanning multiple generations$24

The answer may lie in those four characters, "respectfully deliver the seasons." And Jingzhe was precisely one of the solar terms for which this "delivery of seasons" was most urgently needed. For Jingzhe marked the beginning of spring plowing -- to miss the planting window around Jingzhe meant a year of poor harvests or even famine. In an age with no other standard of time, knowing precisely "when to begin spring plowing" was a matter of life and death for the entire community. It was this pressure of survival that drove the ancients with extraordinary focus and perseverance to observe, day after day, the shadow cast by that gnomon pole, all to capture the precise onset of Jingzhe, the starting point of the agricultural season.

III. The Northern Dipper Points to Mao: Observing the Heavens to Fix Mid-Spring

In addition to shadow observation, the ancients also determined the solar terms by observing the stars, one of the most important methods being the observation of the handle of the Northern Dipper (Big Dipper).

The Heguanzi contains a celebrated passage: "When the Dipper handle points east, all under heaven is spring; when it points south, all under heaven is summer; when it points west, all under heaven is autumn; when it points north, all under heaven is winter." The handle of the Northern Dipper, like an immense celestial pointer, rotates with the turning of the seasons. When the handle points east, it is spring throughout the world.

Within the more refined "Twelve Stations" (shi'er chen) system, the year is divided into twelve months, each corresponding to one of the twelve Earthly Branches (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai). As the Dipper handle completes one rotation per year, its pointing direction (the "jian") indicates the current month. The mid-spring second month in which Jingzhe falls finds the Dipper handle pointing to the Mao position -- hence the second month is also called the "Month of Mao." In the twelve Earthly Branches, Mao corresponds to due east and to mid-spring, fully consistent with "When the Dipper handle points east, all under heaven is spring."

Why did the ancients devote such attention to observing the Dipper handle's direction$25 Because the Northern Dipper held an exalted position in Chinese ancient astronomy. The Records of the Grand Historian (Shiji), in the "Treatise on the Celestial Offices," calls the Northern Dipper the "Emperor's Chariot" (di che), stating that it "moves through the center, commanding the four directions. It divides yin and yang, establishes the four seasons, harmonizes the five phases, shifts the intervals and measures, and fixes all reckonings -- all these are linked to the Dipper." The ancients did not see the Dipper handle as passively indicating the seasons but as actively "establishing" them: when the handle points to Mao, mid-spring arrives and Jingzhe comes. This mode of thought, which fuses stellar phenomena with seasonal order, astronomy with human affairs, is a typical expression of the Chinese cosmology of the unity of Heaven and humanity.

IV. The Mystery of the Character "Mao": Why Is the Second Month of Jingzhe Called the "Month of Mao"$26

The second month in which Jingzhe falls is called the "Month of Mao," and the Dipper handle points to Mao. The character "mao" itself contains meanings deeply consonant with the theme of Jingzhe and warrants specific exploration.

The twelve Earthly Branches are not merely calendrical symbols. In the exegetical tradition from the Han dynasty onward, each branch character was invested with meanings relating to the phenology and climate of its corresponding month. Xu Shen's Shuowen Jiezi offers explanations for these branch characters, often associating them with the state of growth of all things. Regarding "mao," the traditional interpretation holds that "mao" carries the sense of "mao" (to sprout forth) -- all things push through the earth and emerge. By the second month, the creatures roused by spring thunder push up through the ground and poke their heads out; this image of "sprouting forth from the earth" is precisely what the character "mao" seeks to capture.

There is an even more vivid explanation suggesting that the shape of the character "mao" resembles two doors thrown open -- the upper portions parting to either side, as though a portal has been flung wide. The second month is precisely the season when the gates of heaven and earth are thrown open and all things pour forth from their concealment. This image of "the portal thrown open" resonates perfectly with the "qi" (opening) in Jingzhe's original name "Qizhe," and with the Monthly Ordinances' designation of the door-spirit (hu) as the object of worship in mid-spring -- three elements in a trinity, echoing across each other. They all point to the same core image: opening, emerging, moving from interior to exterior, from hiding to action.

Thus the name "Month of Mao" is by no means an arbitrary calendrical symbol. Like "Qizhe," "Jingzhe," and "the sacrifice to the door-spirit," it crystallizes the ancients' grasp of the central theme of the second month of mid-spring: this is a month of "opening," a month when all things push through the earth and surge into action. Whether it is the "Mao" indicated by the Dipper handle, the solar term name "Qizhe/Jingzhe," or the door-spirit worshipped in the Monthly Ordinances, all are speaking the same truth in different languages: the gate of heaven and earth, closed for a whole winter, is in this month thrown open at last.

Chapter Four: The Monthly Ordinances of the Book of Rites -- Mid-Spring: A Complete Cosmic Tableau

I. The Nature of the Monthly Ordinances: An Action Guide Between Heaven and Humanity

Among all pre-Qin texts, the most detailed and systematic description of the mid-spring month in which Jingzhe falls is found in the Monthly Ordinances (Yueling) section of the Book of Rites (its content is largely identical to the "Mid-Spring" section of the Lushi Chunqiu; scholars generally believe the two share a common source). The Monthly Ordinances is not a simple calendrical record but a complete guide to action bridging Heaven and humanity -- it tells us, at a given moment in time, how the heavenly signs appear, how things on earth stand, and how human affairs should be conducted.

The Monthly Ordinances sketches a complete cosmic tableau for the month of mid-spring, opening with:

"In the month of mid-spring, the sun is in the lunar mansion Kui; at dusk, the constellation Hu is at the meridian; at dawn, the constellation Jian is at the meridian."

These three statements identify the sun's position, the constellation at the southern meridian at dusk, and the constellation at the southern meridian at dawn -- the astronomical reference points by which the ancients determined the season.

The Ordinances then describe the Five Phases attributes of mid-spring:

"Its days are jia and yi; its sovereign is Taihao; its spirit is Goumang; its creatures are the scaled; its note is jue; its number is eight; its taste is sour; its smell is rank; its sacrifice is to the door; the organ first offered is the spleen."

This passage constructs an extraordinarily precise system of cosmic correspondences. Let us analyze each in turn.

II. Item-by-Item Reading of the Five Phases Correspondences of Mid-Spring

"Its days are jia and yi" -- The month of mid-spring corresponds to the Heavenly Stems jia and yi. Among the ten Heavenly Stems, jia and yi belong to Wood. Why$27 Because the correspondence between the ten Heavenly Stems and the Five Phases is: jia-yi = Wood (spring), bing-ding = Fire (summer), wu-ji = Earth (late summer), geng-xin = Metal (autumn), ren-gui = Water (winter). Mid-spring belongs to Wood, hence jia and yi.

"Its sovereign is Taihao" -- The presiding sovereign of mid-spring is Taihao (also written as Taixi or Fuxi). Why is the sovereign of spring Taihao$28 This relates to the system pairing the Five Phases with five cosmic sovereigns: the sovereign of spring is Taihao (virtue of Wood), of summer Yandi (virtue of Fire), of the center Huangdi (the Yellow Emperor, virtue of Earth), of autumn Shaohao (virtue of Metal), and of winter Zhuanxu (virtue of Water). Taihao is among the most ancient legendary rulers, traditionally credited with first drawing the Eight Trigrams, creating the written script, and teaching the people to weave nets for fishing. He was a founder of civilization, the first glimmer of human wisdom. To place such a "founder" as the sovereign of spring fits perfectly with spring as the beginning of all things, the inception of life.

"Its spirit is Goumang" -- The assistant deity of mid-spring is Goumang. Goumang is the spirit of Wood and the spirit of Spring in ancient mythology. "Gou" (a variant of "gou," meaning curved or hooked) refers to bending; "mang" refers to the fine, pointed shoot of newly sprouted vegetation. Together, "Goumang" evokes the image of a young plant, curving as it pushes through the soil, its tender shoot reaching upward -- what vivid and precise naming! The Classic of Mountains and Seas (Shanhaijing), "Beyond the Eastern Seas," records: "In the east is Goumang, with the body of a bird and the face of a human, riding two dragons." At the season of Jingzhe, when all things revive, Goumang is the deity who rouses the plants and brings forth all living things.

"Its creatures are the scaled" -- The representative category of creatures for mid-spring is the "scaled creatures" (lin chong), that is, animals with scales, headed by the dragon and including fish and snakes. In the pre-Qin classification of animals, creatures were divided into five categories: scaled (spring), feathered (summer), naked (center/humanity), furred (autumn), and shelled (winter). One explanation for why scaled creatures correspond to spring is that the dragon is their chief, and the dragon is the symbol of spring -- "the dragon raises its head," "the flying dragon is in the heavens." The dragon rises amid clouds and rain in spring, in harmony with the surging yang qi and awakening of all things. Snakes too are scaled creatures, and the snake is a quintessential hibernator -- what Jingzhe rouses includes precisely these concealed scaly beings.

"Its note is jue" -- The musical note of mid-spring is "jue." Among the five notes (gong, shang, jue, zhi, yu), jue corresponds to Wood and to spring. The jue tone is clear and rising, like the sound of branches stretching upward, of life sprouting forth. The ancients believed that each season had its characteristic "sound" -- not that only the jue note could be heard in spring, but that the vibrational frequency of heaven and earth's qi in spring resonated with the frequency of the jue note.

"Its number is eight" -- The symbolic number of mid-spring is eight. In the pre-Qin numerological system, 1 and 6 belong to Water, 2 and 7 to Fire, 3 and 8 to Wood, 4 and 9 to Metal, 5 and 10 to Earth. The "completion number" of Wood is eight, hence its assignment to spring. This system of correspondences between numbers and phases has extremely ancient origins, possibly connected to the traditions of the River Diagram (Hetu) and the Luo Writing (Luoshu).

"Its taste is sour" -- The taste of mid-spring is sour. The correspondence of the five tastes (sour, bitter, sweet, pungent, salty) with the Five Phases is: sour = Wood (spring), bitter = Fire (summer), sweet = Earth (late summer), pungent = Metal (autumn), salty = Water (winter). Why does the sour taste belong to Wood$29 One explanation: sourness has an astringent and saliva-producing quality, and the sap of newly sprouting trees (such as green plums and sour jujubes) tends to be sour. In the ancients' sensory system, taste was not merely a sensation of the tongue but a manifestation of the qi of heaven and earth.

"Its smell is rank (shan)" -- The odor of mid-spring is the rank smell. Among the five odors, the rank smell corresponds to Wood and to spring. It is a grassy, raw scent, consonant with the newly sprouting, freshly stirring quality of spring vegetation.

"Its sacrifice is to the door (hu)" -- The object of sacrifice in mid-spring is the door-spirit. The door is the portal of a house, the place of entry and exit. Why sacrifice to the door in spring$30 Because spring is the season when all things move from inside to outside, from hiding to emergence -- dormant creatures exit their burrows, plants break through the soil, and people step outside to begin spring plowing. The "door" is the portal of passage, symbolizing this movement of "going out." To sacrifice at the door accords perfectly with the theme of "opening" and "emerging" that defines spring. It echoes, from afar, the original meaning of Jingzhe's true name "Qizhe" -- the opening of dormancy.

"The organ first offered is the spleen" -- The organ first presented in sacrifice is the spleen. Regarding the correspondence of the five organs to the Five Phases, different views existed in the pre-Qin era. The Monthly Ordinances here assigns the spleen to spring, which differs from the later medical tradition of assigning the liver to Wood (spring). This reflects variations in the Five Phases correspondence system across different periods and schools. But regardless of the specific assignments, the underlying logic is consistent: every organ of the body corresponds to some dimension of the cosmos, and offering a particular organ in sacrifice expresses the resonance between the human body and heaven and earth.

III. Direction, Color, and the Son of Heaven's Conduct

Summarizing the above correspondences, the cosmic coordinates of the mid-spring month in which Jingzhe falls are clear and complete: its Phase is Wood, its direction is east, its color is blue-green (qing), its presiding sovereign is Taihao, its assistant deity is Goumang, its creatures are the scaled, its note is jue, its number is eight, its taste is sour, its smell is rank, its sacrifice is to the door, its organ offering is the spleen, and its Heavenly Stems are jia and yi. This complete set of correspondences constitutes a total cosmic tableau of "mid-spring."

Based on this system, the Monthly Ordinances prescribes explicit rules for the Son of Heaven's conduct during mid-spring:

"The Son of Heaven resides in the great chamber of the Blue-Green Hall, rides a chariot adorned with luan birds, drives blue-green horses, flies blue-green banners, wears blue-green robes, adorns himself with blue-green jade, eats wheat and mutton, and uses vessels with open, penetrating patterns."

Why must the Son of Heaven wear blue-green and ride blue-green horses in spring$31 This is not an aesthetic preference but a cosmological requirement -- spring belongs to Wood, and the color of Wood is blue-green. As the intermediary between heaven and earth, the Son of Heaven must align all his conduct with the prevailing cosmic principle of the season. Wearing blue-green is not for beauty but to harmonize with the "virtue of Wood" of heaven and earth. The phrase "vessels with open, penetrating patterns" (qi shu yi da) also carries deep significance -- spring is the season when all things unfurl and flow freely; even the patterns on vessels should be open and flowing, symbolizing the unimpeded passage of vital qi.

Embedded here is a profound political philosophy: the ruler does not govern the world by his own will but must follow the Way of Heaven. Every action of the Son of Heaven -- what color to wear, what food to eat, in which direction to reside -- cannot be left to personal whim but must strictly follow the dictates of the Way of Heaven. This both constrains the ruler's power and sacralizes his authority.

IV. The Edicts of Mid-Spring: Bestowing Blessings in Season, Nurturing Vitality

The Monthly Ordinances also prescribes the edicts to be issued in mid-spring, whose core spirit is "bestow blessings in season, nurture vitality." Several entries deserve particular attention:

"In this month... do not drain the rivers and marshes, do not empty the ponds and pools, do not burn the mountain forests." Why not$32 Because mid-spring is the season when all things grow and reproduce; exhausting the waters and burning the forests are acts of "destruction" that run counter to the Way of Heaven's "nurturing" in spring, and must inevitably bring calamity.

"In this month, protect the newly sprouted, nurture the young and small, and succor the orphaned." This entry places nature's "nurturing of the young" alongside society's "care for the orphaned," embodying the spirit of unity between Heaven and humanity -- as heaven and earth protect young plants, insects, and fish, so too must the human world protect young children and succor the destitute. What profound compassion! It elevates observations of nature into ethical demands upon human society.

Beyond "nurturing the young and succoring the orphaned," the Monthly Ordinances specifically mentions: "Reduce the prisons, remove the fetters and shackles, do not inflict excessive flogging, and halt litigation." Why should punishments be lenient in spring$33 Because spring is the season of "life," when the qi of heaven and earth is generative, expansive, and giving. Punishment is "killing," "contracting" -- it belongs to autumn. To issue lenient edicts in spring is to accord with the virtue of Heaven's love of life. This principle of "governing in harmony with the season" is the essence of the Monthly Ordinances -- governance must keep pace with the heavenly seasons: spring generates, summer grows, autumn harvests, winter stores; so too should edicts nurture, fulfill, restrain, and conceal in turn.

V. The Warning of the Monthly Ordinances: Consequences of Untimely Edicts

After describing the proper conduct for mid-spring, the Monthly Ordinances sternly warns of the consequences of improper actions:

"If in mid-spring one implements autumn's edicts, then the state will suffer great floods; cold qi will descend en masse; and invaders will attack. If one implements winter's edicts, then yang qi will fail to prevail; wheat will not ripen; and the people will plunder one another. If one implements summer's edicts, then the state will suffer great drought; warmth will arrive too early; and insect pests will cause harm."

What is the logical basis for these warnings$34 It rests on a core belief: each season has its particular "qi," and edicts too have their particular "qi." Mid-spring is the critical moment when yang qi surges forth, yin and yang contend, and vitality burgeons -- with Jingzhe's thunderclap, yang qi has only just broken through the gloom. At such a delicate threshold, if one issues "untimely" edicts and disturbs the normal ebb and flow of yin and yang, climatic and agricultural disasters will ensue.

From a modern perspective, such causal claims of course lack scientific basis. But if we understand the Monthly Ordinances' warnings from a different angle, they contain a profound political wisdom: governance must have its rhythm. When all things are sprouting and need nurturing, do not be harsh or violent. Though the Monthly Ordinances frames this political wisdom within a cosmological structure of Heaven-humanity resonance, its core insight -- that governance must adapt to the objective needs of society and the rhythms of nature -- retains its value even today.

Chapter Five: The Zhen Hexagram of the Book of Changes -- The Sovereign Emerges from Zhen; Thunder Moves and All Things Are Born

I. The Zhen Hexagram: The Trigram of Thunder

To truly understand Jingzhe, one must delve into the Zhen hexagram of the Book of Changes. For the central image of Jingzhe is thunder, and in the trigram system of the Yijing, the trigram that specifically symbolizes thunder is Zhen.

The trigram image of Zhen is ☳ -- one yang line below, two yin lines above. This image is remarkably evocative: a single yang line stirs beneath two yin lines, symbolizing yang qi rising vigorously from below, breaking through the suppression of yin qi, and shaking upward. Is this not precisely the scene at Jingzhe$35 The yang qi that lay dormant underground through winter, upon reaching mid-spring, suddenly surges forth, breaks through the cold yin of the surface, and manifests as thunder, shaking heaven and earth.

The Shuogua commentary (Explanation of the Trigrams) says: "Zhen is thunder." It also says: "Zhen means movement." The essence of the Zhen trigram is "movement" -- it represents motion, shaking, surging forth, starting up. And this "movement" is not gentle or gradual but swift and explosive, like a crash of thunder suddenly splitting the sky.

The Shuogua further states: "All things emerge from Zhen. Zhen is the east." All things "emerge" from the Zhen trigram -- how perfectly this word "emerge" accords with the "qi" (opening) of "Qizhe" and the theme of Jingzhe as the "awakening of all things"! The Zhen trigram corresponds to the east, to spring, to the season when all things sprout and break through the earth. One can say that the Zhen trigram is the corresponding hexagram image of Jingzhe in the Book of Changes, capturing in the most condensed symbolic form the essential nature of Jingzhe: "thunder moves and all things are born."

II. "The Sovereign Emerges from Zhen": The Master Switch of Cosmic Life

The Shuogua commentary contains a breathtaking statement that is the central key to understanding both the Zhen trigram and Jingzhe: "The sovereign emerges from Zhen" (di chu hu zhen).

What do these four characters mean$36 "The sovereign" (di) is the master of the cosmos, the most fundamental creative force between heaven and earth. "Emerges from Zhen" means that this force issues forth, sets out, and activates from the Zhen trigram. In other words, the stirring of all cosmic life, the genesis of all vitality, has its total beginning and total activation in "Zhen" -- in the movement of thunder, in that surging yang qi.

The Shuogua then describes the complete annual cycle using the Eight Trigrams: "The sovereign emerges from Zhen, is arrayed in Xun, is made visible in Li, is served in Kun, speaks with delight in Dui, does battle in Qian, labors in Kan, and achieves completion in Gen." This is a complete cycle of cosmic life: beginning from Zhen (the start of spring, the birth of all things), passing through Xun (all things purified and arrayed), Li (all things made visible and flourishing), Kun (all things nourished), Dui (all things joyful and mature), Qian (yin and yang do battle), Kan (all things weary and returning to dormancy), and Gen (all things end and begin again). In this cycle, "Zhen" is the starting point, the engine, the master switch that sets everything in motion.

This endows Jingzhe with supreme significance. If "the sovereign emerges from Zhen," and Zhen corresponds to the spring thunder of Jingzhe, then the thunder of Jingzhe does not merely rouse a few hibernating insects -- it is the starting point of the entire cosmic life cycle, the first command issued by "the sovereign" (the creative force) to all things under heaven. The entire year's generating, growing, harvesting, and storing all begin with this single thunderclap. The ancients' awe before Jingzhe's thunder stemmed from precisely this recognition -- what they heard was not an ordinary thunderclap but the opening note of cosmic life, the "sovereign's" first utterance between heaven and earth.

III. "Repeated Thunder, the Image of Zhen; the Noble Person Is Moved to Fearful Self-Examination"

The Great Image commentary on the Zhen hexagram states: "Repeated thunder -- the image of Zhen; the noble person is moved to fearful self-examination" (xian lei zhen, junzi yi kongju xiusheng). "Xian" means repeated, successive. "Repeated thunder" is the image of continuous rolling thunder. The passage says: successive thunder is the image of Zhen; upon observing this hexagram image, the noble person should be filled with fear and engage in self-reflection and self-examination.

This is a profoundly significant statement, revealing the ancients' distinctive attitude toward thunder -- reverence. In the ancients' view, thunder was not merely a sign of yang qi surging forth but a manifestation of Heaven's majesty, a warning and admonition from Heaven to the human world. The rolling thunder seemed as though Heaven were angered, rebuking, reminding. A person of virtue, upon hearing thunder, would not remain unmoved but would feel awe, reflecting on whether any word or deed had been a transgression, whether anything had violated the Way of Heaven.

Why could thunder inspire "fearful self-examination"$37 Because in the cosmology of the unity of Heaven and humanity, Heaven and humans are interconnected and mutually responsive. Heaven's pleasure and anger manifest through natural phenomena; human good and evil likewise resonate with Heaven. Thunder is the most direct, most awe-inspiring manifestation of Heaven's majesty. When thunder sounds, the noble person instinctively turns inward: Have I committed some injustice that has disturbed Heaven$38 This "fearful self-examination" is not a superstitious fear of natural phenomena but an awe before the Way of Heaven -- an exalted spiritual attitude that links one's moral responsibility to the cosmic order.

The spring thunder of Jingzhe is the beginning of these "repeated thunders." When the first thunder of the year sounds, it is for the noble person an occasion for "fearful self-examination" -- at the start of the new year's agricultural endeavors, as yang qi surges and all things awaken, first examine oneself and set one's mind aright, then approach and participate in heaven and earth's nurturing with a purified, reverent spirit. This way of linking the solar terms tightly with moral cultivation is a hallmark of the Confucian interpretation of the seasons, which we shall develop further in the chapter on the Confucian perspective.

IV. "Thunder Startles for a Hundred Li, Yet He Does Not Lose the Sacrificial Ladle and Libation"

The hexagram statement of the Zhen hexagram contains another deeply suggestive passage: "When the thunder comes, there is alarm and trembling (xixi); then laughter and words of cheer (yaya). Thunder startles for a hundred li, yet he does not lose the sacrificial ladle (bi) and the libation of aromatic wine (chang)." "Xixi" describes a state of fearful vigilance; "yaya" describes relaxed, cheerful speech. The "bi" is a ladle used to scoop offerings in ancestral temple sacrifices; "chang" is the aromatic wine used in sacrifice. The passage means: when thunder strikes, one first trembles with fearful vigilance, then can speak and laugh at ease once more. Thunder startles all within a hundred li, yet the person presiding over the sacrifice remains so steadfast that neither the ladle nor the libation wine is dropped.

What grandeur of spirit! This passage praises a composure in the face of upheaval, a constancy in the midst of great change. When earth-shaking thunder arrives, all things tremble and hearts are seized with panic, yet the truly virtuous person of inner fortitude, after the initial moment of awe, swiftly regains composure, poised and unruffled, holding the sacrificial vessels steady without the slightest faltering.

Here lies a profound lesson in cultivation. Thunder symbolizes the sudden upheavals, shocks, and impacts that come from the outside world. Faced with such upheaval, the ordinary person is likely to lose composure and become confused. The cultivation of the noble person is revealed precisely in the ability to "not lose the ladle and libation" in the face of upheaval -- to maintain inner steadiness, proper conduct, and fidelity to what is constant. Jingzhe's thunder awakens all things, a form of violent "movement." Within this "movement," the noble person must be able to hold fast to inner "stillness" and "composure." Stillness within movement, constancy amid change -- this is the supreme state that Chinese philosophy seeks to attain.

From this, we see that the Zhen hexagram offers a twofold lesson: on the one hand, it tells us to follow the "movement" -- to accord with the surging of yang qi and the awakening of life, to engage actively in the new year's labor and striving. On the other hand, it admonishes us to maintain "composure" within movement -- not to let external shaking uproot our inner foundations. This wisdom of cultivating both movement and stillness is a precious spiritual legacy that the Jingzhe solar term bestows upon us.

V. The Image of Thunder in Literature: From the Book of Songs to the Songs of Chu

Thunder is not merely an object of philosophy but also a mother-motif in literature. The poems of the pre-Qin era contain vivid and deeply felt depictions of this phenomenon so charged with power and mystery. Through these literary images we can feel more intimately the complex spirit with which the ancients faced thunder.

The Book of Songs (Shijing), in "Yin Qi Lei" ("Rolling Thunder") from the Shao Nan section, is a celebrated piece that begins with thunder as a stimulus: "Rolling, rolling is the thunder, on the sunny slope of the southern hill. Why must he go from here, never daring to rest$39 O noble lord so earnest, come home, come home!" The phrase "yin qi lei" imitates the deep, awe-inspiring rumble of thunder. The poem takes the rolling thunder beside the southern hill as its opening image to express a wife's longing for her husband, who is away on the king's service. Here thunder serves as both real landscape and emotional catalyst -- the rolling thunder shakes the earth and also shakes the longing wife's heart, stirring her boundless yearning for her distant beloved. The "movement" of thunder and the "movement" of the human heart merge into one.

In "Zhong Feng" ("Gusting Wind") from the Bei Feng section, thunder also appears: "Dark and overcast the sky, rumbling faintly the thunder." "Huihui" imitates the low, rumbling sound of thunder about to break. Overcast skies and distant thunder -- this oppressive, uneasy weather exactly matches the gloom and sorrow of the poem's speaker. Clearly, in the world of the Book of Songs, thunder is frequently used in correspondence with human emotions and moods. The shake of thunder, its distant rumbling, its sudden crash -- all become media through which the poet gives voice to inner feeling. This embodies the literary expression of "Heaven-humanity mutual responsiveness": the stirring of thunder above and the stirring of emotion below are fundamentally connected.

By the time of the Songs of Chu (Chuci), the image of thunder takes on more mythological color and romantic atmosphere. The deities depicted by Qu Yuan in the Nine Songs typically appear accompanied by spectacular visions of thunder, lightning, wind, and cloud. In passages from pieces such as "The Lord amid the Clouds" (Yun Zhong Jun), with their magnificent imagery of "riding the dragon, wheels rumbling, soaring high to the heavens," and their divine landscapes woven from wind, cloud, thunder, and lightning, thunder is elevated to something sacred and sublime. In Qu Yuan's verse, thunder is no longer merely awe-inspiring heavenly power but has become a splendid backdrop for communion between Heaven and humanity, for spiritual journeys to the eight extremities. The rumble of thunder is the prelude to the gods' descent, the most magnificent music between heaven and earth.

From the Book of Songs to the Songs of Chu, the literary image of thunder underwent an enrichment from "realistic lyricism" to "romantic mythology." But whether it is the longing-inducing "rolling thunder" of the Book of Songs or the divine thunder-and-lightning journeys of the Songs of Chu, they share one fundamental quality: thunder is powerful, awe-inspiring, and capable of bridging Heaven and humanity. And Jingzhe's thunder, as the year's first thunderclap, is the very wellspring of all these literary imaginings. When the ancients heard that first spring thunder at Jingzhe, what welled up within them was perhaps precisely this complex blend of awe, emotion, wonder, and poetic feeling -- which ultimately crystallized into those immortal thunder-poems of the Book of Songs and the Songs of Chu.

Chapter Six: The Dazhuang Hexagram -- Four Yang Lines Ascendant; the Noble Person Does Not Tread Where Propriety Forbids

I. The Dazhuang Hexagram: The Second Month in the Twelve Waxing-and-Waning Hexagrams

Beyond the Zhen trigram, understanding Jingzhe requires yet another indispensable hexagram image -- Dazhuang (Great Vigor). This involves a vitally important system in the Book of Changes: the Twelve Waxing-and-Waning Hexagrams (shi'er xiaoxi gua).

The Twelve Waxing-and-Waning Hexagrams correlate twelve hexagrams with twelve months, illustrating the process of yin-yang waxing and waning over the course of a year. "Waning" (xiao) refers to the growth of yin and decline of yang; "waxing" (xi) refers to the growth of yang and decline of yin. These twelve hexagrams, read from bottom to top, use the gradual increase of yang lines (or yin lines) to represent the waxing and waning of yang qi, forming a complete picture of yin-yang alternation:

Eleventh month: Fu (Return, one yang born at the bottom); twelfth month: Lin (Approach, two yang lines); first month: Tai (Peace, three yang -- "Three Yangs Usher in Auspiciousness"); second month: Dazhuang (Great Vigor, four yang lines ascendant); third month: Guai (Breakthrough, five yang lines); fourth month: Qian (Heaven, six yang, pure yang) -- after which yin qi begins to sprout -- fifth month: Gou (Encounter, one yin born); sixth month: Dun (Withdrawal, two yin); seventh month: Pi (Stagnation, three yin, three yang); eighth month: Guan (Contemplation, four yin ascendant); ninth month: Bo (Stripping, five yin stripping yang); tenth month: Kun (Earth, six yin, pure yin).

The second month (Month of Mao) in which Jingzhe falls corresponds precisely to the Dazhuang hexagram. Dazhuang is composed of four yang lines below and two yin lines above. In terms of the hexagram image, yang qi has grown to four lines -- a situation of yang qi "ascendant in vigor." After the Fu hexagram's return of one yang, the Lin hexagram's two yang, and the Tai hexagram's three yang, by the time we reach the second month's Dazhuang, yang qi has seized an overwhelming advantage in the lower four positions and is pushing upward with unstoppable force. This is the most fitting hexagram portrait of Jingzhe's surging yang qi, earth-shaking thunder, and the rising of all things.

II. "Thunder above Heaven, Great Vigor": The Image of Thunder Soaring above the Sky

The structural image of the Dazhuang hexagram itself is replete with the resonance of Jingzhe. The lower trigram of Dazhuang is Qian (Heaven, ☰), and the upper trigram is Zhen (Thunder, ☳). Thus Dazhuang is also called "Thunder above Heaven" (lei tian dazhuang).

The Image commentary of the Dazhuang hexagram states: "Thunder above heaven -- Great Vigor." Imagine the scene: thunder, that surging yang qi, has risen above heaven itself, crashing and reverberating, awe-inspiring in all directions. Compared with the Zhen trigram (thunder rising from beneath the earth), this represents a further stage -- in Zhen, yang qi has just broken through the surface, while in Dazhuang, it has ascended to the sky, its momentum even grander and more vigorous.

This precisely corresponds to the evolution of yang qi from Lichun (Beginning of Spring) to Jingzhe. At Lichun, yang qi has just stirred, still germinating underground. By Jingzhe, yang qi has grown strong enough to burst through the surface, manifest as thunder, and shake heaven and earth -- this is "Great Vigor," this is "Thunder above Heaven." The lower trigram Qian (Heaven, pure yang) represents a resolute, upward-moving force; the upper trigram Zhen (Thunder, movement) represents a surging, shaking force. Together they present a scene of yang ascendancy, robust vitality, and irrepressible momentum.

Why is this hexagram called "Great Vigor" (Dazhuang) and nothing else$40 The Tuan (Judgment) commentary explains: "Great Vigor: what is great is vigorous. Strength moves, hence vigor." "Great" (da) refers to yang -- yang is great, yin is small. "What is great is vigorous" means yang qi has grown strong. "Strength moves, hence vigor" -- the virtue of firm strength (Qian) combined with the momentum of vigorous movement (Zhen) produces "vigor." This is exactly the spirit of Jingzhe: yang qi (the great) has become vigorous; firm and striving, irresistible.

III. "The Noble Person Does Not Tread Where Propriety Forbids": Restraint amid Vigor

Yet the deepest wisdom of the Dazhuang hexagram lies not in its description of "vigor" but in its admonition regarding vigor. The Great Image commentary delivers a supremely pointed statement: "Thunder above heaven -- Great Vigor; the noble person does not tread where propriety forbids" (junzi yi fei li fu lu).

What does this mean$41 Thunder above heaven, yang qi ascendant -- this is the image of Great Vigor. Upon observing this image, the noble person should refrain absolutely from doing anything that violates propriety (li, ritual propriety) -- "lu" meaning to walk, to practice, to do.

What profound insight! Why must one emphasize "not treading where propriety forbids" precisely when yang qi is at its most vigorous$1

Because "vigor" is a double-edged sword. Vigorous yang qi means abundant vitality and overflowing strength -- a good thing. But at the peak of vigor, one is most prone to excess, to violence, to recklessness. The stronger the force, the more tempting it is to abuse it. The more surging the energy, the more easily it spins out of control into destruction. Therefore, it is precisely at the moment of "Great Vigor" -- when strength is at its peak -- that the noble person must exercise the highest self-restraint and self-discipline, using "propriety" (li) to regulate all speech and conduct, and absolutely refusing to do anything that violates it.

This reveals a profound dialectic: power and restraint. True "vigor" is not the brute force that charges forward heedless of all else, but force constrained by propriety, a force that knows what to do and what not to do. The Tuan commentary adds: "Great Vigor is favorable when correct. What is great must be correct. Correct and great -- and the true nature of heaven and earth can be discerned." True greatness must have "correctness" (zheng) as its prerequisite. Only greatness that is upright, open, and in accord with propriety and righteousness is worthy of affirmation; otherwise, vigor without rectitude degenerates into disorder.

At Jingzhe, this wisdom is most needed. At the year's start, with yang qi surging and all things rising, one is full of eager ambition -- and rightly so. But precisely at such moments of high spirits and abundant energy must one understand the principle of "not treading where propriety forbids": this surging force must be channeled into the track of propriety, becoming constructive and measured rather than being allowed to run wild. This is the solemn admonition that the Dazhuang hexagram offers to Jingzhe and to every person who strives forward: strength must be tempered; vigor must be grounded in rectitude.

IV. The Combined Reading of Zhen and Dazhuang: The Twofold Hexagram Wisdom of Jingzhe

We have now seen that Jingzhe is linked to two hexagram images in the Book of Changes: the Zhen trigram ☳ as the fundamental trigram of thunder, and the Dazhuang hexagram as the waxing-and-waning hexagram of the second month. These two hexagrams, from different angles, together reveal the deeper wisdom of Jingzhe.

The Zhen trigram tells us "the sovereign emerges from Zhen" -- Jingzhe's thunder is the beginning of cosmic life, the activation of creative force. It also tells us "repeated thunder, the noble person is moved to fearful self-examination" -- before heavenly majesty, one should be awed and self-reflective. And it tells us "thunder startles for a hundred li, yet he does not lose the ladle and libation" -- constancy in the face of upheaval.

The Dazhuang hexagram tells us "Thunder above Heaven, Great Vigor" -- at Jingzhe, yang qi is ascendant and irrepressible. It also tells us "the noble person does not tread where propriety forbids" -- amid vigor there must be restraint; strength must be channeled within the track of propriety. And it tells us "what is great must be correct" -- true greatness must have rectitude as its premise.

Viewing these two hexagrams together, we arrive at a complete, dialectical life wisdom: on one hand, follow the "movement" -- accord with the surging of yang qi, actively engage, and throw oneself into life's labor. On the other hand, maintain "measure" within that movement -- exercise self-discipline through propriety, hold firm amid change. To move with measure, to be vigorous yet correct, to strive yet remain self-aware -- this is the core spirit that Jingzhe conveys through the two hexagrams of the Book of Changes. It is by no means a simple encouragement to "rise up" but rather, while encouraging rising, an earnest admonition to understand restraint and rectitude. This profoundly dialectical wisdom is what makes ancient Chinese philosophy most precious.

Chapter Seven: The Phenological World (Part I) -- Peach Trees Begin to Bloom: A Declaration of Life in Full Splendor

I. An Overview of Jingzhe's Three Pentads

The Shixun Jie (Explanations of the Seasonal Instructions) section of the Yi Zhou Shu (Lost Book of Zhou) provides detailed phenological descriptions for each solar term. Regarding Jingzhe, it records: "On the day of Jingzhe, peach trees begin to bloom; after another five days, the orioles sing; after another five days, hawks transform into pigeons."

These are the "Three Pentads" (san hou) of Jingzhe: first pentad -- peach trees begin to bloom; second pentad -- orioles begin to sing; third pentad -- hawks transform into pigeons (doves).

These three phenological markers derive respectively from the plant kingdom (peach blossoms), the avian world (orioles), and a phenomenon of imaginative "metamorphosis" (hawks becoming pigeons). Together they paint a vivid picture of how the earth transitions from deathly stillness to flourishing vitality during Jingzhe. The ancients' practice of using changes from three different domains to mark Jingzhe and grasp the season reflects a simple yet meticulous empirical sensibility.

Notably, the Shixun Jie also records the consequences of phenological disorder: "If peach trees do not begin to bloom, it is called 'yang blocked.'" "If orioles do not sing, ministers do not obey the ruler." "If hawks do not transform into pigeons, marauders and invaders will rise repeatedly." These interpretations of "anomalies" lack scientific basis by modern standards, yet they reflect the ancients' deeply held conviction: natural order and human order are interconnected. When the qi of heaven and earth falls into disarray, the human world inevitably suffers as well. This concept of "Heaven-humanity resonance" is the key to understanding pre-Qin solar term culture.

We should first understand the concept of a "pentad" (hou). The ancients called a five-day period one "pentad"; three pentads (fifteen days) constituted one "qi" -- this is the origin of "qi" in "solar term" (jieqi). Twenty-four solar terms per year, each containing three pentads of fifteen days, yields seventy-two pentads in all. For each pentad, the ancients assigned a signature phenological phenomenon (an animal behavior, a plant change, or a weather sign), thus composing a "phenological calendar" that tracked the pulse of life year-round in five-day increments. This seventy-two pentad system represents the pinnacle of the ancients' minute observation of nature -- they did not merely divide the year into four seasons but captured, with five-day granularity, every subtle phenological change. Jingzhe's "peach trees begin to bloom, orioles sing, hawks transform into pigeons" are the three pentads assigned specifically to Jingzhe. Through them, we perceive the ancients' nearly devotional, scrupulously attentive observation of heaven and earth's rhythms.

II. Peach Trees Begin to Bloom: Why Peach Blossoms$2

First pentad: "peach trees begin to bloom" -- peach blossoms start to open. Why did the ancients choose the peach blossom as the first phenological marker of Jingzhe$3

The peach blossom is one of early spring's most emblematic flowers. Its season of bloom, right in mid-spring, coincides perfectly with Jingzhe. When peach trees burst into flower, those trees ablaze with vivid, radiant, passionate red become the most direct and moving announcement of the earth's revival. If spring thunder is Jingzhe's auditory marker, then the peach blossom is its visual marker -- one clap of thunder awakens all things; one tree of blossoms announces spring's arrival.

On a deeper level, peach blossoms carry extraordinarily rich symbolic meaning in Chinese culture. The peach -- red and brilliant, radiant and passionate -- symbolizes the surging of yang qi and the vigor of life. The blooming of peach flowers signifies that yang qi has become abundant enough to bring forth blossoms -- a theme perfectly aligned with Jingzhe's "surging yang qi." A tree of peach blossoms is a poem of splendor that yang qi writes among the plants and trees.

Moreover, since high antiquity the peach has been invested with mysterious powers to ward off evil and protect life. The ancients believed that peachwood possessed the power to repel malevolent forces; peach charms, peach figurines, and peach bows were all instruments used to drive away evil. This belief may be related to the peach tree's early spring blooming and vigorous vitality -- amid the lingering desolation of early spring, the peach tree is the first to proclaim life's return with its profusion of blossoms. The ancients regarded this robust vitality as a masculine force capable of dispersing the yin and sinister and protecting life. At Jingzhe, as yang qi disperses the cold of yin and rouses all things, the peach blossom is the representative of this "yang dispelling yin" force in the plant kingdom.

III. "Tao Yao" of the Book of Songs: The Timeless Lyric of Splendid Blossoms

Speaking of peach blossoms, one cannot fail to mention that timeless poem from the Book of Songs -- "Tao Yao" (Zhou Nan):

"Lovely is the peach tree, ablaze are its blossoms. This maiden goes to wed -- may she bring harmony to her household. Lovely is the peach tree, plump are its fruits. This maiden goes to wed -- may she bring harmony to her home. Lovely is the peach tree, luxuriant are its leaves. This maiden goes to wed -- may she bring harmony to her kin."

"Lovely is the peach tree, ablaze are its blossoms" (tao zhi yaoyao, zhuozhuo qi hua) -- the peach tree is so young and flourishing, its blossoms so vividly radiant. "Yaoyao" evokes the youthful, luxuriant bearing of the tree; "zhuozhuo" evokes the vivid, luminous color of its flowers. In just eight characters, the image of a tree in full bloom is rendered so lifelike it leaps from the page -- what brilliance, what passion, what overflowing vitality!

This poem was originally a wedding blessing, using the peach blossom to celebrate a bride. Yet its depiction of peach blossoms has become the quintessential portrait of Jingzhe. Why has this poem resonated with countless people across millennia$4 Because the four characters "zhuozhuo qi hua" (ablaze are its blossoms) capture the dazzling beauty of life at its peak. The blooming of the peach is an unreserved, exhilarating burst of vitality -- unlike the plum blossom's cold solitude or the chrysanthemum's defiance of frost, the peach proclaims life's return and abundance in the most passionate, fullest, most unconcealed way.

Worth savoring is how "Tao Yao" progresses from "ablaze are its blossoms" (flowering) to "plump are its fruits" (fruiting) to "luxuriant are its leaves" (leafing out), fully tracing the peach tree's life cycle from blossom through fruit to lush foliage. This implies a deep philosophy of life: the splendor of the flower is only the beginning; it must ultimately progress to "fruit" (substance) and "luxuriance" (fullness). When the peach begins to bloom at Jingzhe, it is only a start -- it foreshadows that throughout the coming spring and summer, all things will move from flower to fruit, from sparse to abundant, toward the fullness and completion of life.

IV. Peach Blossoms and the "Flowering of Heaven and Humanity": The Botanical Portrait of Yang Qi

Let us press one layer deeper: when the ancients observed peach blossoms, were they merely admiring a natural beauty$5

In the cosmology of Heaven-humanity unity, the blooming of peach blossoms was by no means an isolated natural phenomenon but a sign of the movement of heaven and earth's qi, a "portrait" of surging yang qi in the plant kingdom. Why do peach blossoms bloom at Jingzhe$6 Not because the peach tree "decided" to, but because the yang qi of heaven and earth has reached the stage where this is the inevitable result. When yang qi is sufficiently abundant, it propels the peach tree's vitality to burst forth in blossoms. Thus, when the ancients observed peach blossoms, they saw not merely flowers but the qi pervading all of heaven and earth behind those flowers.

This is why the ancients attached such importance to these subtle phenological changes. In their cosmology, heaven, earth, and all things form an organic whole; any local change reflects the direction of the whole. A single peach blossom's opening, in the ancients' eyes, was a signal of the Way of Heaven's operation, evidence that yang qi was surging. By observing the peach blossom, they confirmed that the yang qi awakened by the spring thunder had indeed pervaded heaven and earth and was bringing forth all things.

From this we can understand the distinctive reverence the ancients brought to their observation of phenology. When they looked at a tree of peach blossoms, they saw the vitality of the entire cosmos. When they savored the "ablaze blossoms," they were savoring the irrepressible life force between heaven and earth. "Peach trees begin to bloom" is Jingzhe's first pentad and is also the earth's first "reply" to the sky -- Heaven calls with thunder, and the earth answers with peach blossoms. In this call and response lies the most moving unfolding, at Jingzhe, of the ancient cosmos of mutual resonance and ceaseless generation.

Chapter Eight: The Phenological World (Part II) -- Orioles Sing and Hawks Transform into Pigeons: The Mysteries of Sound and Metamorphosis

I. Orioles Sing: The Oriole's Song of Spring

The second pentad of Jingzhe is "the orioles sing" (canggeng ming). What is a "canggeng"$7 It is the oriole, also known as the yellow warbler (huangli or huangying). With its golden plumage and its clear, melodious song, it is one of spring's most enchanting singers. "Canggeng ming" means that by the second five-day period of Jingzhe, the orioles have begun to sing.

If the first pentad, "peach trees begin to bloom," is Jingzhe's visual marker, then the second pentad, "orioles sing," is another auditory marker -- added to the rumble of spring thunder comes the warbling of the oriole. One robust, one delicate; one majestic, one beautiful: spring thunder is the heroic voice of surging yang qi, and the oriole's song is the limpid voice of stirring vitality. Together they compose the "soundscape" of the earth's revival at Jingzhe.

Why did the ancients select the oriole's song as a phenological marker$8 Because birdsong is one of the most sensitive indicators of seasonal change. The oriole sings as the weather warms -- for courtship, for territorial proclamation. This is essentially an expression of life force being stirred and awakened by the yang qi of spring. A bird sings because the vitality within it surges with the rising yang qi and must be expressed as sound. Thus the oriole's song, like the peach blossom's opening and the dormant creature's awakening, is a manifestation of surging yang qi across different life forms.

The Book of Songs also frequently features the oriole (canggeng). "Qi Yue" ("Seventh Month") of the Bin Feng section has: "In the sunny days of spring, the oriole sings." "Chu Che" ("Dispatching Chariots") of the Xiao Ya section has: "The orioles sing cheche; those gathering artemisia are many." These verses closely link the oriole's song to spring's arrival and the stirring of vitality. In the ancients' experience, hearing the oriole's first song was like receiving a formal invitation from spring -- the earth was not merely reviving; it had begun to "sing."

II. Hawks Transform into Pigeons: A Puzzling Phenological Marker

The third pentad of Jingzhe is "hawks transform into pigeons" (ying hua wei jiu) -- the most extraordinary and thought-provoking of Jingzhe's three pentads. It states that by the third five-day period of Jingzhe, hawks have transformed into turtledoves (or cuckoos).

This obviously does not accord with modern biological knowledge -- how could a hawk possibly turn into a dove$9 The two birds are biologically unrelated. Why, then, did the ancients hold this seemingly absurd view$10

To understand "hawks transform into pigeons," we must return to the ancients' observational perspective. One plausible explanation: around mid-spring, fierce raptors gradually become less visible (some say hawks enter their breeding season and become more secretive; others say they migrate northward), while at the same time, gentle doves become more abundant and active in their calling. Seeing that the birds of prey formerly circling overhead have vanished and been replaced by flocks of doves, and noting certain similarities between hawks and doves in size and flight posture, the ancients conceived the idea that "hawks have turned into doves."

But this explanation touches only the surface. The reason "hawks transform into pigeons" was important enough to be solemnly recorded as a phenological marker is that it embodies a profoundly significant philosophical concept -- "transformation of things" (wuhua), symbolizing the principle of yin-yang transmutation. This requires dedicated discussion.

III. The Philosophy of Transformation: The Insight of Master Zhuang

The character "hua" (transform) in "hawks transform into pigeons" is the key to understanding this phenological marker. In pre-Qin philosophy, "hua" is an extremely important concept, referring to the transmutation and metamorphosis of things. The philosopher who developed the philosophy of "hua" to its fullest was Master Zhuang (Zhuangzi).

Master Zhuang, at the close of the "Qi Wu Lun" ("Discussion on Making All Things Equal"), tells the famous story of the Butterfly Dream: "Once upon a time, Zhuang Zhou dreamed he was a butterfly -- a fluttering butterfly, content and carefree, knowing nothing of Zhou. Suddenly he awoke, and there he was -- solidly and unmistakably Zhou. He did not know whether he was Zhou who had dreamed he was a butterfly, or a butterfly dreaming it was Zhou. Between Zhou and the butterfly, there must be some distinction. This is called the Transformation of Things (wuhua)."

"The Transformation of Things" -- the transmutation of one thing into another. Master Zhuang uses the butterfly dream to show that the boundaries between things are not as sharp as we suppose. Zhuang Zhou can "transform" into a butterfly, and a butterfly can "transform" into Zhuang Zhou. At a deeper level, all things are in perpetual transformation; nothing is permanently fixed.

Master Zhuang also opens the "Xiaoyao You" ("Wandering in Absolute Freedom") with another astonishing "transformation": "In the northern darkness there is a fish called Kun. The Kun is so large that no one knows how many thousand li it measures. It transforms into a bird called Peng." A fish transforms into a bird! With this magnificent imagination, Master Zhuang tells us: "transformation" is a fundamental mode of movement in the cosmos, and the forms of all things can undergo astonishing change.

Within this philosophical vision of "transformation of things," "hawks transform into pigeons" no longer seems absurd. In the ancients' view, hawk and dove are merely different manifestations of the same life force (qi) under different seasonal conditions. In autumn and winter, when the qi of severity prevails, the life force manifests as the fierce hawk. In mid-spring, when the qi of generation prevails, the life force manifests as the gentle dove. The hawk "transforming" into the dove symbolizes the transmutation from "severity" to "generation," from "yin" to "yang" -- precisely the core theme of the Jingzhe solar term.

IV. Hawks Transform into Pigeons: A Phenological Symbol of Yin-Yang Transmutation

Let us situate "hawks transform into pigeons" within the overall context of Jingzhe.

The hawk is a raptor, fierce and deadly, symbolizing the "killing qi" of autumn and winter -- autumn is the season of "the falcon strikes," when all things are harvested and culled. The dove is a gentle bird, mild and peaceable, symbolizing the "generating qi" of mid-spring -- it is active and vocal in spring, consonant with the generation of all things. From hawk to dove, from fierce to gentle, from killing to generating -- this transmutation is a symbol of the qi of heaven and earth turning from the severity and closure of winter to the generation and exuberance of spring.

This is the deeper meaning behind "hawks transform into pigeons" being listed as one of Jingzhe's three pentads. It is not merely an isolated biological observation but a microcosm of a grand cosmic narrative about "yin-yang transmutation." Jingzhe is the critical moment of this transmutation -- the thunderclap of spring, the surging of yang qi, the exit of the severe and the entrance of the generative. And "hawks transform into pigeons" is the most vivid, most concrete phenological symbol that the ancients found for this great transmutation.

More exquisitely still, the autumn phenology contains a phenomenon that is the exact reverse. The Monthly Ordinances records that in mid-autumn, "doves transform into hawks" (jiu hua wei ying)! In spring, hawks become doves; in autumn, doves become hawks -- a perfect circuit of reciprocal transformation. This cycle symbolizes the waxing and waning of yin and yang qi: in spring, yang grows and yin diminishes, so the hawk (yin, killing) transforms into the dove (yang, generating); in autumn, yin grows and yang diminishes, so the dove (yang, generating) transforms back into the hawk (yin, killing). Through this pair of opposite yet complementary "transformations," the ancients depicted the cosmic law of yin-yang cycling and seasonal reciprocation with consummate vividness.

This dialectical understanding of "change and constancy" is pre-Qin philosophy's most profound contribution to the interpretation of the solar terms. It makes us realize that what Jingzhe marks is not the "birth" of something new but the "transformation" of the same life force (qi) between different forms. The hawk has not "died"; it has merely "transformed" into a dove. Winter has not "vanished"; it has merely "transformed" into spring. The qi of heaven and earth has never ceased flowing -- it merely changes its form as it flows. We establish the marker "Jingzhe" precisely to note and remind ourselves of this continuous, subtle, great transformation from yin to yang, from dormancy to action.

Chapter Nine: Yin-Yang and the Five Phases -- Thunder as the Surging of Yang Qi; the First Stirring of the Virtue of Wood

I. Thunder: The Surging Forth of Yang Qi

To understand Jingzhe from the perspective of yin-yang and the Five Phases, one must first grasp what "thunder" means within this cosmological system. What is thunder$11 In the ancients' view, thunder is not simply a weather phenomenon -- it is the sound of yang qi surging forth and bursting through yin qi.

The Huainanzi, in its "Treatise on Celestial Patterns," explains the formation of thunder and lightning as the result of the violent collision and agitation of yin and yang qi. This reflects a widespread pre-Qin and Han-era conviction: thunder and lightning are generated by the fierce contest of the two qi. In winter, yang qi is dormant underground, sealed and suppressed by heavy yin qi. As the seasons progress, yang qi underground grows ever more powerful. By mid-spring, it accumulates to a critical point and erupts upward, violently colliding with the yin qi above -- this collision, expressed as sound, is thunder; expressed as light, is lightning.

Therefore, the essence of thunder is the explosive moment when yang qi surges forth and breaks through the bonds of yin qi. It is the proclamation of yang qi's triumph over yin qi, of vitality over deathly stillness. Jingzhe's thunder is the moment when, for the first time in the year, yang qi announces its victory to heaven and earth in so spectacular and powerful a fashion -- winter's closure is broken, yang qi has burst forth, and life is about to begin!

Understanding this, we can appreciate why Jingzhe's thunder is so important. It is not an ordinary sound but a marker of the fundamental reversal in the balance of yin and yang forces. Before Jingzhe, although yang qi has been steadily growing (from the Fu hexagram to Dazhuang), it remains hidden underground, not yet manifested so violently or openly. Jingzhe's thunder is yang qi's first eruption through the gloom with the force of "thunderbolts," shaking heaven and earth. From this point forward, yang qi will dominate the first half of the year, and generation and growth will become the dominant theme of heaven and earth.

II. The Yin-Yang Configuration at Jingzhe: Four Yang Ascendant, Yang Dominates and Yin Submits

From the perspective of the Twelve Waxing-and-Waning Hexagrams, the second month of Jingzhe corresponds to the Dazhuang hexagram (four yang, two yin). This means that by Jingzhe, the yin-yang balance has undergone a decisive shift: yang qi has grown to four lines, seizing an absolute advantage; yin qi has retreated to the upper two lines, in a defensive posture. This is a situation of "yang dominates and yin submits," with yang qi ascendant and rising while yin qi declines.

Yet we must note that at Jingzhe, the yin-yang configuration is not pure yang without yin but one of yang ascendancy and yin decline, with the two still contending. Two yin lines remain atop Dazhuang -- indicating that yin qi has not fully withdrawn and is making its last stand. This explains why the weather around Jingzhe is often erratic, shifting between warm and cold: this is the final contest between yang qi and yin qi. Warmth is the advance of yang; cold is the counterattack of yin. This unstable state of yin-yang contention is the internal cause of mid-spring's changeable weather.

And thunder is precisely the product of the most intense point of this yin-yang contention. Without contention between yin and yang, there would be no thunder. It is only during seasons of fierce yin-yang collision that we get the explosive thunder of yang qi striving to break free of yin qi's blockade. Jingzhe's thunder is the triumphant roar of yang qi in its final battle against yin qi.

III. The First Stirring of the Virtue of Wood: The Full Unfolding of Generative Qi

From the perspective of the Five Phases, the mid-spring of Jingzhe belongs to Wood. We already discussed in detail in Chapter Four the Monthly Ordinances' Wood-virtue correspondences (Sovereign Taihao, Spirit Goumang, scaled creatures, the jue note, the sour taste, and so on). Here we press further: What is the essential nature of "the virtue of Wood"$12 What is the relationship between Jingzhe and this virtue$13

"Wood" among the Five Phases does not refer merely to trees but is a cosmic mode of energy -- representing generation, upward movement, expansion, and flowing openness. The characteristic of Wood is "bending and straightening" (Shangshu, "Hongfan": "Wood is called bending and straightening"), meaning the capacity to bend and extend, to grow upward and spread outward. This generative, upward, expansive energy is the dominant energy of spring.

Jingzhe is the critical node at which this "virtue of Wood" fully unfolds. At Lichun, the virtue of Wood first stirs, like a seed barely sprouting, its generative power still faint. By Jingzhe, with the shock of spring thunder and the surging of yang qi, the generative power of Wood is fully activated and released -- plants break through the soil, peach trees blossom, dormant creatures awaken, birds begin to sing. All life burgeons under the impetus of Wood's virtue. If Lichun is the "ignition" of Wood's virtue, then Jingzhe is its "acceleration" -- from this moment, generative qi is no longer a trickle but a rushing torrent.

Noteworthy here is the relationship between "thunder" and "Wood." In the Five Phases system, thunder (the Zhen trigram) belongs to Wood -- the Shuogua explicitly states that Zhen is thunder, and in the Five Phases correspondences Zhen belongs to Wood, to the east, and to spring. This unifies "thunder" and "the virtue of Wood": thunder is the sound of Wood's virtue surging forth; when the generative power of Wood reaches a certain degree, it manifests as thunder. Thus, Jingzhe's thunder and Jingzhe's Wood virtue are essentially two manifestations of the same generative qi -- one auditory (the thunder), one material (the sprouting of vegetation). Together they compose the complete picture of Jingzhe's core theme: "generation."

IV. Jingzhe within the Cycles of Generation and Conquest: Water Generates Wood; Wood Generates Fire

The Five Phases stand in relationships of mutual generation and mutual conquest. The order of generation is: Water generates Wood, Wood generates Fire, Fire generates Earth, Earth generates Metal, Metal generates Water. The order of conquest is: Water conquers Fire, Fire conquers Metal, Metal conquers Wood, Wood conquers Earth, Earth conquers Water.

Within this system, the "Wood" represented by Jingzhe occupies a pivotal, bridging position. From the perspective of "Water generates Wood," the virtue of Wood is born from winter's virtue of Water. Winter's storing and nourishing (the virtue of Water governs storing) prepares the energy for spring's generation (the virtue of Wood). This is why winter's dormancy must precede Jingzhe's awakening: without winter's "storing" (Water), there can be no spring's "movement" (Wood). The reason dormant creatures can surge forth at Jingzhe is precisely that they have stored sufficient vitality during their winter hibernation. This accords with "The dragon and the snake hibernate in order to preserve their lives" -- dormancy (the virtue of Water) prepares the way for generation (the virtue of Wood).

From the perspective of "Wood generates Fire," Jingzhe's virtue of Wood in turn gestates the summer virtue of Fire. The generation of Wood ultimately progresses toward the greatness of Fire -- spring's generative qi pushes forward until, in summer, it develops into the blazing fullness of Fire. Thus Jingzhe's generation is not an endpoint but a starting point -- the first step on the path toward the full growth and flourishing of spring and summer.

From this we see that Jingzhe occupies a crucial pivot in the Five Phases cycle. It receives winter's nourishing (Water generates Wood) and opens the way to summer's flourishing (Wood generates Fire). One clap of spring thunder activates the entire chain of life's transition from winter's "storing" to spring's "moving" to summer's "growing." This is the profound significance of Jingzhe within the yin-yang Five Phases cosmology -- it is the great pivot at which the qi of heaven and earth turns from stillness to movement, from concealment to expression, from yin to yang; it is the engine that restarts the cycle of life.

V. Thunder's Beginning and Its Cessation: The Life History of Thunder across the Year

Since thunder symbolizes the surging of yang qi, the "emergence" and "withdrawal" of thunder over the course of a year precisely mark one complete cycle of yang qi's waxing and waning. Examining the "life history" of thunder across the four seasons allows us to understand more deeply the unique status of Jingzhe's thunder.

Jingzhe is the season when "thunder first sounds" (lei shi fa sheng) -- the moment when yang qi has, for the first time, grown strong enough to break through yin qi and manifest as thunder. Throughout the entire winter before Jingzhe, no thunder is heard, for yang qi still lies dormant underground, firmly locked away by yin qi, unable to give voice. Only at Jingzhe, when yang qi accumulates to its critical point, does it surge forth and emit the first spring thunder. Thus Jingzhe's thunder is the "first thunder" (shi lei), the "first cry" (chu ti) of yang qi, the beginning of thunder's life in the year.

At the other end of the year -- mid-autumn -- there is the phenological marker "thunder begins to withdraw its sound." The Monthly Ordinances records for mid-autumn: "In this month, day and night are equal, and thunder begins to withdraw its sound." Around the Autumn Equinox, the days and nights are equal, and thunder begins to quiet and rumble no more. Why does thunder "withdraw" in autumn$14 Because yin qi is waxing and yang qi waning; yang qi no longer has sufficient force to surge forth as thunder, so thunder falls silent, goes into hiding, and waits for the following year. From mid-autumn's "thunder begins to withdraw" through the deep silence of winter to the following year's Jingzhe "thunder begins to sound" -- thunder passes through a complete cycle from "withdrawing" to "hiding" to "emerging."

This contrast between "first sounding" and "withdrawing" is deeply significant. Jingzhe's thunder-sounding corresponds to yang qi's rising and life's awakening; mid-autumn's thunder-withdrawing corresponds to yang qi's ebbing and life's return to dormancy. The "emergence" and "withdrawal" of thunder precisely mark the two critical nodes in the year's waxing and waning of yang qi -- one is the turning point where yang qi overcomes yin qi (Jingzhe), the other where yin qi overcomes yang qi (mid-autumn). By observing the "beginning" and "cessation" of thunder, the ancients grasped the pulse of yang qi's annual rise and fall. This once again confirms the exquisite subtlety of the ancients' observation: they did not merely listen to thunder but, from the "presence" and "absence" of thunder, from its "sounding" and "withdrawing," read the deep, vast breathing of yin and yang between heaven and earth. And Jingzhe's thunder, as the beginning of that breathing's "inhalation," as the first bugle call of yang qi's surge, occupies a position of singular eminence and importance in the entire rhythm of the cosmos.

Chapter Ten: Agriculture and Human Affairs -- When Spring Thunder Sounds, Farm Work Begins

I. "Once Jingzhe Has Passed, Spring Plowing Cannot Rest"

If the preceding chapters addressed the significance of Jingzhe on the planes of philosophy, astronomy, and phenology, this chapter addresses its most tangible meaning, the one most directly affecting livelihood: Jingzhe is the marker for the beginning of spring plowing.

China has many agricultural proverbs linking Jingzhe to farming, the most widely known being: "Once Jingzhe has passed, spring plowing cannot rest," "If you don't plow at Jingzhe, within three to five days you'll regret it," and "When the ninth period ends and willows flower, all farm work arrives at once." These homespun sayings express a fundamental fact: Jingzhe marks the true beginning of the year's agricultural work.

Why Jingzhe$15 Because Jingzhe signals the rise in air temperature and soil temperature. After the clap of spring thunder, the weather warms, the soil thaws, and conditions are right for plowing and planting. To miss this window is to fall behind in the farming season and imperil the year's harvest. For the ancestors who lived by agriculture, Jingzhe was not an abstract calendrical concept but a concrete "mobilization order" -- it told every farmer: the restful winter is over; it is time to go to the fields!

This grounds all the philosophical meaning we discussed earlier in the most basic agricultural practice. The "jing" of "Jingzhe" rouses not only the creatures underground but also the farmers in the fields. Dormant creatures are startled awake by spring thunder and emerge from the earth; farmers are startled awake by spring thunder and go out to labor. Between Heaven and humanity, at the Jingzhe solar term, the most tangible synchronization is achieved. The ancients observed the awakening of dormant creatures essentially to find, for their own farming, a basis in heavenly timing -- if even the dormant creatures have come out, the soil temperature must be sufficient for planting.

II. The Ultimate Fulfillment of "Respectfully Delivering the Seasons"

In the introduction we cited the ideal of "respectfully delivering the seasons" from the Book of Documents. If the entire system of solar terms is a product of this ideal, then Jingzhe is its most critical "fulfillment."

Why$16 Because among the twenty-four solar terms, Jingzhe is the one directly linked to "spring plowing" -- the single most important agricultural activity. The core purpose of "delivering the seasons" is to tell the people "when to sow." And the time to sow falls precisely around Jingzhe. If the timing is wrong -- sowing too early when it is still cold, the seeds will freeze; sowing too late past Jingzhe, the farming season will be missed. Accurately determining Jingzhe was therefore the most critical and demanding task in the sacred enterprise of "respectfully delivering the seasons."

This explains why the ancients took such pains to determine Jingzhe through multiple methods -- shadow measurement, stellar observation, phenological verification -- and repeatedly confirmed their findings. The livelihoods of millions depended on it; the survival of entire communities hung in the balance. Determining Jingzhe was not an academic exercise but a matter of life and death. The high regard in which the ancients held Jingzhe ultimately stemmed from agriculture's absolute dependence on time.

The Book of Songs, in "Qi Yue" ("Seventh Month") of the Bin Feng section, describes the year's agricultural cycle in detail: "In the third day-count, attend to the plowshare; in the fourth day-count, lift the foot" -- in the first month of the Xia calendar, repair the farming tools; in the second month, begin going to the fields (literally, "lift the foot," ju zhi, meaning to step into the field). The "fourth day-count" here roughly corresponds to the mid-spring second month of Jingzhe. This shows that already in the era of the Book of Songs, the ancients took mid-spring as the start of the plowing season. The phrase "lift the foot" is especially vivid -- the farmer lifts a foot, strides toward the field, and begins the year's hard labor. That single lifted foot is the most tangible answer to the summons of Jingzhe's spring thunder.

III. Jingzhe and "Rousing the Insects": Phenological Wisdom in Agriculture

Jingzhe rouses not only creatures beneficial to farming but also harmful ones. This introduces an interesting dimension of agricultural life at Jingzhe -- coping with pests.

Around Jingzhe, as dormant creatures awaken, various pests also begin to stir. The ancients noticed this early on and developed customs and wisdom in response. For example, in some regions, Jingzhe customs include "frying the insects" or "beating the petty person" -- essentially psychological responses and symbolic acts of expulsion against the revival of pests at Jingzhe. Farmers would also take advantage of the brief window before pests proliferated to plow and clear fields, keeping pest damage to a minimum.

Behind this lies a simple yet profound phenological wisdom: follow the heavenly seasons, seek advantage and avoid harm. Jingzhe rouses all things, among which are beneficial creatures (like the earthworm that loosens soil) and harmful ones (like crop-eating insects). The wise farmer does not blindly fight against nature but follows nature's rhythms, doing the right thing at the right time -- plowing when it is time to plow, clearing pests when it is time to clear them. This attitude of "following heavenly timing while doing one's human best" is the essence of China's traditional agrarian wisdom.

IV. The Human Stirring: From Dormancy to Rising as a Life Metaphor

Jingzhe's significance for human affairs extends beyond agriculture. It is a profound metaphor for the stirring of the human spirit.

Winter is a season of dormancy -- not only for insects but for people as well. In winter, during the farming off-season, people rest and recuperate, storing energy, just as dormant creatures store vitality underground. When Jingzhe arrives and spring thunder sounds, it is the call for people to emerge from dormancy, to strive and advance. If winter is "storing," then Jingzhe is the beginning of "movement" -- the moment when the year's struggles and labors formally commence.

This transition from "dormancy" to "rising" holds deep lessons for every person. Life, too, has its own "winters" and "Jingzhe moments." In periods of adversity, frustration, or building strength, we are like hibernating creatures, turning inward, storing power, waiting for the moment -- this is "zhe." When the time is ripe and opportunity arrives, we must rise like the dormant creature at the sound of thunder, surging into action, seizing the moment, giving our all -- this is "jing." The capacity to bend and to extend, to hide and to move -- to hibernate when hibernation is called for (nourishing strength), and to surge when surging is called for (striving forward) -- this is the life wisdom that the Jingzhe solar term bestows upon us. We shall deepen this reflection in the dedicated chapter on the "Way of bending and stretching."

Chapter Eleven: Cultivation of Body and Mind -- Nourishing Health and the Stirring of Spirit at Jingzhe

I. Following Yang Qi: The Fundamental Principle of Health Cultivation

The fundamental principle of health cultivation at Jingzhe can be stated in four words: follow the yang qi.

The Yellow Emperor's Inner Classic (Huangdi Neijing), in the "Great Treatise on Regulating the Spirit in Accordance with the Four Qi" (Siqi Tiaoshen Da Lun), though compiled somewhat later, has its health-cultivation thought deeply rooted in pre-Qin ideas of the Heaven-humanity relationship. On the Way of nourishing life in the three months of spring, it says:

"The three months of spring are called 'bursting forth and display.' Heaven and earth together generate; all things flourish. Retire late and rise early; stride broadly through the courtyard; let the hair hang loose and relax the body, so that the will may be born. Generate and do not kill; give and do not seize; reward and do not punish. This is the response to the qi of spring, the Way of nourishing life."

This passage is the guiding principle for spring health cultivation (which naturally includes Jingzhe). "Bursting forth and display" (fa chen) -- pushing out the old and displaying the new; all things in spring unfurl what has been stored. "Heaven and earth together generate; all things flourish" -- both heaven and earth are in their generative mode, and all things thrive accordingly. In such a season, what should a person do$17 "Retire late and rise early" -- one may go to bed a little later but should rise early, in accord with the lengthening daylight and the rising yang qi. "Stride broadly through the courtyard" -- take leisurely walks in the courtyard, stretching the body. "Let the hair hang loose and relax the body" -- wear the hair unbound, relax the frame, avoid constraint. "So that the will may be born" -- let one's intention and spirit come alive.

Why "let the hair hang loose and relax the body" and "so that the will may be born"$18 Because spring is a season of generation and expansion. Correspondingly, the human body and spirit should be in a state of expansion, generation, and freedom from constraint. If in spring one still bundles up tightly and contracts the spirit as in winter, one contravenes the Way of Heaven's "generation" in spring, to the detriment of health. At Jingzhe, when yang qi surges, the body's yang qi also rises accordingly; this is precisely the time to let body and mind unfurl, allowing vitality to grow freely.

II. "Generate and Do Not Kill; Give and Do Not Seize": The Unity of Nourishing Health and Nourishing Virtue

The Great Treatise continues: "Generate and do not kill; give and do not seize; reward and do not punish."

On the surface these lines discuss health cultivation, but in reality they unify the nourishing of body with the nourishing of virtue and of mind. They tell us that health cultivation at Jingzhe is not merely physical (rising early, walking, stretching) but also pertains to character and disposition -- one should cultivate attitudes of "generating," "giving," and "rewarding," and set aside attitudes of "killing," "seizing," and "punishing."

What profound insight! It reveals a truth: body and mind are one; health cultivation cannot be separated from the cultivation of the heart. A person harboring thoughts of harshness, grasping, and severity, even if they rise early and walk daily, will struggle to achieve true health. Conversely, a person whose heart is full of generativity, generosity, and warmth, attuned to the generative qi of spring, will naturally tend toward health. At Jingzhe, when heaven and earth brim with vitality, if one can fill one's heart with the same vitality -- magnanimity, generosity, encouragement, aspiration -- this itself is the finest health cultivation. This is the essence of the Chinese tradition of "nourishing both form and spirit" and "nourishing health by first nourishing the heart."

III. Thunder and the Heart-Mind: Emotional Cultivation at Jingzhe

Jingzhe takes thunder as its central image, and in the theory of Chinese medicine, thunder bears subtle connections with the "heart" (xin) and the "liver" (gan). From the perspective of emotional cultivation, Jingzhe has its special considerations.

On one hand, spring belongs to Wood, and Wood corresponds to the liver. The liver governs the free flow of qi (shuxie) and smooth openness (tiaoda); it delights in ease and resents depression. At Jingzhe, the liver qi rises with yang qi, reaching its most vigorous state but also its greatest need for release. If at this time the emotions are depressed and the liver qi stagnates, various discomforts may arise. Thus, health cultivation at Jingzhe requires particular attention to maintaining cheerful spirits and emotional openness, allowing the liver qi to rise smoothly, just as plants should be allowed to grow freely. This again confirms the wisdom of "so that the will may be born" -- letting the will and emotions come alive and expand is the core of Jingzhe health cultivation.

On the other hand, Jingzhe's thunder reminds us of the earlier discussion of "fearful self-examination" and "not losing the ladle and libation." Thunder symbolizes sudden upheaval and shock from the outside world. In the context of health, this tells us that when faced with the sudden reversals, pressures, and stimuli of life (life's "thunderclaps"), we should cultivate a spirit of calm composure, not allowing external upheavals to disturb our inner equilibrium. To maintain "stillness" amid "startlement," to hold "composure" amid "movement" -- this is not only a moral cultivation but also a Way of nourishing health, for violent, prolonged emotional swings are most injurious to the body. At Jingzhe, one must at once follow yang qi by surging and stretching forth, and within that surging hold fast to inner steadiness -- this is the dialectical unity of body-mind cultivation at this solar term.

IV. Diet and Daily Life: The Specific Practices of Jingzhe Health Cultivation

In the specifics of diet and daily routine, Jingzhe health cultivation has its own particular considerations, all derived without exception from the fundamental principle of "following the heavenly seasons."

In daily routine, as noted above, one should "retire late and rise early," in accord with the lengthening daylight; "stride broadly through the courtyard," exercising moderately, stretching the body to assist the rising of yang qi. Jingzhe, when yang qi surges, is an excellent time for outdoor activity and excursions into nature; prolonged confinement indoors and lethargy are inadvisable.

In diet, the traditional health cultivation principle at Jingzhe is to "reduce sourness and increase sweetness, to nourish the spleen qi." Why$19 Because in spring the liver qi is already naturally exuberant (Wood is in ascendancy), and the sour taste enters the liver. If one eats too much sour food, the liver qi becomes excessive and will overwhelm the spleen-earth (Wood conquers Earth). Therefore, one should actually reduce sour flavors and increase sweet ones, supplementing the spleen qi to harmonize liver and spleen. This is a concrete application of Five Phases conquest theory in health cultivation -- adjusting diet to balance the qi of the organs, preventing any one organ's qi from becoming overactive and injuring the others. Additionally, in folk tradition, eating pears at Jingzhe is customary, as the weather is suddenly warm yet dry, and pears can moisten dryness, generate fluids, clear heat, and transform phlegm -- another seasonally attuned health practice.

From all this we can see that every detail of Jingzhe health cultivation -- rising early, walking, stretching, reducing sour and increasing sweet, eating pears -- is pervaded by a single principle: follow the heavenly seasons, maintain harmony with the qi of heaven and earth. The essence of health cultivation is not to "fight" aging with supplements, but to synchronize the rhythms of body and mind with the rhythms of heaven and earth. At Jingzhe, a time of surging yang qi and abundant vitality, to let body and mind also surge with vitality -- this is the highest art of nourishing life.

Chapter Twelve: Ritual and Ceremony -- The Suburban Sacrifice, Welcoming Spring, and Folk Customs of Jingzhe

I. "After Qizhe, the Suburban Sacrifice": Jingzhe and the Suburban Sacrifice to Heaven

Jingzhe held an important place in the ancient ritual system, most prominently through its association with the "suburban sacrifice" (jiao ji).

The Zuo Zhuan, in the fifth year of Duke Huan, records: "For all sacrifices: after Qizhe, the suburban sacrifice; when the dragon appears, the rain prayer; when killing begins, the autumn tasting sacrifice; when hibernation closes, the winter steaming sacrifice." This passage records the timing of four major annual sacrifices: after Qizhe (Jingzhe), the "suburban sacrifice" (sacrifice to Heaven); when the Azure Dragon constellation appears (roughly early summer), the rain prayer (yu); when the killing qi of autumn begins, the autumn tasting sacrifice (chang); and when creatures go into hibernation (roughly early winter), the winter steaming sacrifice (zheng).

Here it is explicitly stated: "After Qizhe, the suburban sacrifice" -- the suburban sacrifice to Heaven is held after Jingzhe. Why was the suburban sacrifice scheduled after Jingzhe$20 Behind this lay profound ritual logic. The suburban sacrifice was the most solemn of all sacrifices -- a sacrifice to Heaven itself. Scheduling it after Jingzhe was because Jingzhe marked the surging of yang qi, the revival of all things, and the formal beginning of the year's nurturing. At this moment of burgeoning vitality, sacrificing to Heaven was precisely to express gratitude for Heaven's bestowal of vitality and to pray for favorable weather and bountiful harvests throughout the year. One can say that "after Qizhe, the suburban sacrifice" linked Jingzhe to the highest-level sacrifice to Heaven, highlighting Jingzhe's exalted position in the ritual system as "the beginning of the year's nurturing."

This confirms the point we have repeatedly emphasized: in the ancients' conception, Jingzhe was not an ordinary solar term but a moment of cosmic and sacred significance. It was not only the starting point of agricultural work but also the occasion for sacrifice -- a solemn moment when humanity expressed awe and gratitude toward Heaven.

II. Welcoming Spring at the Eastern Suburb: The Ritual System of Greeting the Four Seasons

The mid-spring in which Jingzhe falls belongs to the domain of "spring." In the ancient ritual system, spring had an extremely important ceremony -- the Welcoming of Spring (ying chun).

The Monthly Ordinances of the Book of Rites records that in the first month of spring: "On the day of Lichun, the Son of Heaven personally leads the Three Excellencies, the Nine Ministers, the feudal lords, and the grandees to welcome spring at the eastern suburb." Why the eastern suburb$21 Because east belongs to Wood, and spring comes from the east. Welcoming spring at the eastern suburb (east = Wood), summer at the southern suburb (south = Fire), autumn at the western suburb (west = Metal), and winter at the northern suburb (north = Water) -- the directions for greeting each season strictly follow the Five Phases directional system.

Although the formal "Welcoming of Spring" ceremony took place at Lichun, the entire spring season (including the mid-spring of Jingzhe) was suffused with the ritual atmosphere of "welcoming spring," "praising spring," and "nurturing spring." Throughout mid-spring, the Son of Heaven continued to reside in the Blue-Green Hall, wear blue-green garments, and ride blue-green horses, with all conduct aligned with the virtue of Wood (as detailed in Chapter Four). This practice of bringing the entire spring season under a set of ritual norms consonant with "the virtue of Wood" and "generation" embodies the fundamental spirit of "aligning ritual with Heaven" -- synchronizing human order with the rhythm of the Way of Heaven through a complete set of ritual behaviors.

The spring-welcoming ceremony also included the important custom of "whipping the spring ox" (bian chun niu). The ancients fashioned a spring ox from clay, and at Lichun officials would ceremonially whip it, symbolizing the encouragement and urging of farming. Although this custom was associated mainly with Lichun, its spirit of "urging the plowing" and "encouraging agriculture" was perfectly consonant with Jingzhe's theme of "spring plowing begins." Whipping the spring ox was essentially a ritualized way of reminding and urging people: the farming season has arrived; it is time to begin working. This resonates with Jingzhe's thunder "startling" farmers into the fields.

III. Sacrificing to the White Tiger and "Beating the Petty Person" at Jingzhe

Jingzhe also has some distinctive folk customs. Though many of these took shape in later periods, their spiritual core can still be traced back to the ancients' understanding of Jingzhe's theme of "rousing all things."

The first is "sacrificing to the White Tiger." In some regions, Jingzhe includes the custom of worshipping the White Tiger, seen as a deity of gossip and quarrels. The ancients believed that as all things awaken at Jingzhe, various quarrels, gossip, and petty antagonists also "awaken" and become active. Thus one sacrificed to the White Tiger, praying for it to suppress such troubles and ensure a peaceful year. This custom essentially extends Jingzhe's theme of "rousing the dormant" from the natural world (rousing hibernating creatures) into the human world (stirring up petty persons and quarrels) -- since Jingzhe awakens all dormant things, the dormant "evils" (quarrels, antagonists) are also awakened, and must be ritually warded off.

The second is "beating the petty person" (da xiaoren). Related to the White Tiger sacrifice, this involves symbolically striking paper figurines representing "petty persons" with shoes or other objects, to drive out antagonists and dispel bad luck. This similarly reflects the Jingzhe-era belief that "all things (including malicious persons and events) awaken," as well as the ancients' simple desire to seek good fortune and avoid harm.

Though these folk customs carry elements of popular religious belief, their underlying logic aligns with the Yijing's "repeated thunder, the noble person is moved to fearful self-examination" -- all embody a heightened vigilance at this moment of "awakening." When all things (both good and evil) are roused, one must strive forward (responding to yang qi), guard against malevolent forces (warding off evil), and examine oneself (fearful self-reflection). This attitude, at once proactive and prudent, is the deep survival wisdom the ancients formed in facing Jingzhe, a solar term charged with power and unpredictability.

IV. The Essence of Ritual: Responding to Heavenly Timing with Human Affairs

Reviewing these various rites and folk customs associated with Jingzhe -- the suburban sacrifice, the spring welcoming, whipping the spring ox, sacrificing to the White Tiger, beating the petty person -- we cannot help but ask: What is the essence of these rituals$22

Their essence is "responding to heavenly timing with human affairs." In the cosmology of Heaven-humanity unity, the operation of the Way of Heaven (such as the surging of yang qi at Jingzhe) and the arrangement of human affairs (such as sacrifice and farming) should maintain synchronization and mutual responsiveness. Ritual (li) is precisely the means of achieving this "synchronization." Through a complete set of ritualized behaviors, humans align their activities with the rhythm of the Way of Heaven, unifying human order with cosmic order.

Master Xun (Xunzi) offered a profoundly penetrating discussion of "ritual." He said: "Heaven and earth thereby unite; sun and moon thereby shine; the four seasons thereby keep their order; the stars thereby move; the rivers thereby flow; all things thereby flourish... This is called the Great Foundation." In Master Xun's view, ritual is not a human invention but shares its source and principle with the operation of heaven and earth, sun and moon, four seasons, and stars. Heaven has the order of the four seasons; humanity has the order of ritual -- the two are fundamentally one. Jingzhe's various rites serve precisely to align the human "order" with the heavenly "order," to make human conduct resonate with heaven's rhythm.

This is the ultimate significance of Jingzhe's rituals: they are not empty formalities but a bridge between Heaven and humanity. Through these ceremonies, the ancients placed themselves within the grand order of heaven, earth, and the cosmos -- they gave thanks to Heaven for its gifts through the suburban sacrifice, echoed spring's arrival through the spring welcoming, and answered thunder's summons through their labor. Behind all these rituals lies a heart of infinite reverence for the Way of Heaven and longing to be one with it. And this is the deepest spiritual coloring of Chinese ritual-and-music civilization.

Chapter Thirteen: The Mythology of Thunder -- Fenglong, the Thunder God, and the Ancient Echoes of Goumang

I. Thunder as Deity: The Ancients' Awe and Imagination before Thunder

Thunder is Jingzhe's most central image. And in the hearts of the ancient peoples, thunder was far more than a natural phenomenon -- it was a god, an embodiment of heavenly majesty, an entity charged with mysterious power.

Why did the ancients deify thunder$23 This is entirely understandable. Imagine, in that remote age devoid of scientific knowledge, when people saw the sky suddenly darkened by dense clouds, lightning tearing the firmament, thunder crashing and echoing, the very earth trembling -- what a stunning, terrifying spectacle! This immense, incomprehensible force, capable of destroying trees and buildings and even taking human life, was naturally perceived by the ancients as something supernatural and sacred. And so thunder was deified -- it became the voice of Heaven, Heaven's wrath, the manifestation of Heaven's will.

This awe before thunder is already evident in the Yijing's "repeated thunder, the noble person is moved to fearful self-examination." On the plane of mythology, this awe evolved into splendid imaginings about "thunder deities." The ancients believed that behind that rumbling thunder, there was a deity (or deities) governing lightning and thunder. This chapter explores the ancient faces of these thunder gods and examines what echoes Jingzhe's thunder awakened in the mythological world.

II. Fenglong: The Thunder God in the Songs of Chu

In pre-Qin texts, the thunder god bears several names, one important one being "Fenglong."

The name "Fenglong" appears primarily in the Songs of Chu. Qu Yuan, in the Li Sao (Encountering Sorrow), writes: "I bade Fenglong ride upon the clouds, to seek where the Lady of the Luo might be found." Here "Fenglong" is annotated by Wang Yi as the "Cloud Master" (some say Thunder Master). In the magnificent, fantastical mythological world of the Songs of Chu, Fenglong is a deity capable of riding clouds, summoning wind and thunder -- a capable messenger for Qu Yuan's journeys through heaven and earth in pursuit of his ideals.

The name "Fenglong" itself is charged with divine resonance. "Feng" connotes abundance and grandeur; "long" connotes rumbling and magnificence. Together, "Fenglong" seems to imitate the rolling, rumbling, grand, and overwhelming sound of thunder. By giving the thunder god such a name, the ancients sought to capture thunder's qualities of grandeur, sonority, and soul-shaking power.

In the Songs of Chu, Fenglong stands alongside many other deities (such as Wangshu, Feilian, the Lady of the Luo, and others) in a brilliant mythological pantheon. This pantheon reflects the rich and romantic mythological imagination of the Chu region (the south). The thunder god Fenglong's ability to ride clouds and mediate between heaven and earth embodies the ancients' understanding of thunder's special power as a "connector of heaven and earth" -- thunder descends from the sky and shakes the earth; it is a medium linking Heaven and earth, the divine and the human. And Jingzhe's thunder is the first grand manifestation of this "connecting" power -- Heaven uses thunder as its emissary, transmitting to the sleeping earth the decree: "It is time to awaken."

III. The Image of the Thunder God: From the Classic of Mountains and Seas to Folk Imagination

Beyond Fenglong, the ancients held other imaginings of the thunder god. The Classic of Mountains and Seas (Shanhaijing) provides one particularly important image.

The Shanhaijing, in "Within the Eastern Seas," records: "In the Marsh of Thunder (Leize) there is a thunder god, with the body of a dragon and the head of a human, who beats his belly. It is west of Wu." In the Marsh of Thunder lives a thunder god with a dragon's body and a human head, who strikes ("beats") his belly (to produce thunder). This is an image of extraordinary primitive imagination: the thunder god has a dragon's body and a human head; the sound of thunder comes not from any instrument or tool but from the god beating his own belly -- his stomach is an immense drum, and each slap produces a heaven-shaking crash!

This "belly-beating thunder" image, in its simplicity and vividness, reflects the ancients' naive yet poetic explanation of what causes thunder. In their minds, that rumbling thunder sounded like a giant or deity beating a drum. In later ages, this imagination evolved into the more concrete image of the "Thunder Duke" (Lei Gong) -- wielding mallet and drum (or axe and chisel), who with each strike produces a thunderbolt.

The thunder god's "dragon body" is also noteworthy. The dragon, as discussed earlier in the context of "scaled creatures," symbolizes spring and the surging of yang qi. That the thunder god has a dragon's body links thunder to the dragon, to spring, and to the surging of yang qi. In spring, the dragon rises amid clouds and rain; in spring, thunder crashes and rouses all things -- dragon and thunder are different mythological expressions of the same force: "yang qi surging, shaking heaven and earth." At Jingzhe, when "the dragon raises its head" and thunder first sounds, dragon and thunder take the stage together, performing the overture to the year's revival of life.

IV. Goumang: The Spring God Who Awakens the Plants

Accompanying the thunder god is another deity of vital importance to Jingzhe -- Goumang. We already introduced him in Chapter Four's discussion of the Monthly Ordinances correspondences; here we expand further.

Goumang is the spirit of Wood and the spirit of Spring in ancient mythology, the assistant deity of mid-spring. The Shanhaijing, "Beyond the Eastern Seas," records: "In the east is Goumang, with the body of a bird and the face of a human, riding two dragons." Goumang has a bird's body and a human face, and rides two dragons -- an image similarly suffused with primordial divinity.

The name "Goumang" was explicated earlier: "gou" (curved) and "mang" (the tender tip of a newly sprouted plant). "Goumang" captures the image of new growth curving upward, its tender shoot pushing through the earth. If the thunder god (Fenglong, Lei Gong) governs the "startling" -- rousing all things with thunder -- then Goumang governs the "generating" -- propelling the sprouting and growth of plants. The thunder god is responsible for "waking them up"; Goumang is responsible for "making them grow." The two collaborate to accomplish Jingzhe's great work of "rousing and generating all things."

Goumang's image of "riding two dragons" and having "a bird's body" is also suggestive. "Riding two dragons" links Goumang to the dragon (symbol of spring and yang qi); "a bird's body" links him to birds (symbols of rising, upward movement). Both dragon and bird symbolize an ascending, rising, exuberant force -- precisely the essence of spring, of the virtue of Wood, and of Jingzhe's generative qi. Goumang, with this image charged with rising force, presides over spring's sprouting of vegetation -- the ancients' personification and deification of "generative force."

Thus we see a complete mythological tableau of Jingzhe: the thunder god (Fenglong, Lei Gong) rouses all things with thunderbolts; the spring god Goumang propels the plants to sprout and grow; the dragon rises amid clouds, bringing rain -- Heaven, earth, gods, and dragon together enact Jingzhe's grand revival of life. These myths are by no means mere "stories" fabricated by the ancients but their poetic, profound understanding of this sacred moment. In an age before the rise of science, myth was the way the ancients grasped the world and understood the Way of Heaven. And through these myths, we today can still touch the complex, deep feelings the ancients experienced before spring thunder and the revival of life -- a blending of awe, wonder, and gratitude.

V. Taihao and the Marsh of Thunder: The Imprint of Thunder upon the Spring Sovereign

The presiding sovereign of mid-spring is Taihao (Fuxi). Intriguingly, in ancient legend, the birth of this Spring Sovereign also bears a hidden connection to "thunder" -- adding yet another mythological depth to Jingzhe's thunder theme.

According to tradition, Fuxi's mother, Lady Huaxu, stepped into a giant footprint in the "Marsh of Thunder" (Leize) and thereby conceived, giving birth to Fuxi. This legend is recorded in multiple ancient texts. As we noted earlier, the Shanhaijing records that "in the Marsh of Thunder there is a thunder god, with the body of a dragon and the head of a human, who beats his belly" -- the Marsh of Thunder is precisely where the thunder god dwells. Lady Huaxu trod on the giant footprint in the Marsh of Thunder (said by some to be the thunder god's footprint) and bore Fuxi, thereby linking Fuxi's birth intimately to the thunder god and the Marsh of Thunder. In other words, this Spring Sovereign who presides over spring and over Jingzhe's mid-spring -- Taihao (Fuxi) -- can trace the source of his very life to that thunder-charged marsh.

This is no coincidence but a necessity of mythological logic. The Spring Sovereign Taihao presides over the spring in which all things germinate, and the core driving force of spring is the thunder that surges and shakes and rouses all things. To link the Spring Sovereign's birth to the Marsh of Thunder and the thunder god is to unify, on the plane of myth, "spring" and "thunder," "the sovereign of generation" and "the power of thunderbolts." Fuxi is both the founder of civilization who first drew the Eight Trigrams (the dawn of wisdom) and the Spring Sovereign born from the resonance of thunder (the source of life) -- within his person, the great power of creation, surging, and inaugurating that "thunder" symbolizes is concentrated.

Thus Jingzhe's mythological tableau becomes ever more complete and profound: the Spring Sovereign Taihao, born from the resonance of thunder, presides on high over spring's nurturing; the thunder god Fenglong and Lei Gong rouse all things with thunderbolts; the spring god Goumang propels the plants to sprout; and thunder, the driving force behind all, runs through everything, serving both as the life-source of the Spring Sovereign and as the awakening power of all things. In this mythological system, "thunder" is elevated to a position that is original and generative -- it not only rouses life but is itself one of life's sources. And Jingzhe is the annual grand appearance of this creative thunder. That the ancients surrounded Jingzhe's thunder with such rich and profound mythology speaks to how solemn and sacred, in their hearts, the significance of this spring thunder truly was.

Chapter Fourteen: Musical Tuning -- The Sound of Jiazhong and the Harmony of Heaven and Earth

I. The Twelve Pitch-Pipes and the Twelve Months: A Cosmology of Unified Music and Calendar

In ancient China, musical tuning was far more than a matter of music alone -- it bore profound connections to the calendar, the solar terms, and the operation of the cosmos. This is the principle known as "the unity of pitch-pipes and calendar" (lu li he yi) -- musical pitch and calendrical reckoning are one; both are manifestations of the rhythmic operation of the qi of heaven and earth.

Specifically, the ancients divided the musical scale into twelve pitch-pipes (lu): Huangzhong, Dalv, Taicu, Jiazhong, Guxian, Zhonglv, Ruibin, Linzhong, Yize, Nanlv, Wuyi, Yingzhong. These twelve pitch-pipes correspond to the twelve months of the year: Huangzhong to the eleventh month (Zi), Dalv to the twelfth month (Chou), Taicu to the first month (Yin), Jiazhong to the second month (Mao), and so on through the cycle.

The second month (Month of Mao) in which Jingzhe falls corresponds to "Jiazhong" among the twelve pitch-pipes. That is, from the perspective of musical tuning, the "sound" of the Jingzhe season is the Jiazhong tone.

Why can musical pitch correspond to the months$1 Behind this lies a profoundly deep cosmology: the waxing and waning of heaven and earth's qi over the year is rhythmic, possessed of a "beat." Musical pitch is the sonic expression of this cosmic rhythm. Each month's qi of heaven and earth has its particular "frequency," and this frequency corresponds to one of the twelve pitch-pipes. In other words, the ancients believed that the operation of heaven and earth's qi was itself a grand "musical composition," and the twelve pitch-pipes were its twelve notes.

II. The Name "Jiazhong": Assisting All Things, Gathering Yang Qi

The name "Jiazhong" itself carries deep meaning worthy of careful reflection.

"Jia" has the sense of flanking, assisting, supporting; "zhong" has the sense of gathering, collecting, concentrating (and is also cognate with "zhong," meaning to plant, to gestate). The ancients' naming of the twelve pitch-pipes often embedded their understanding of the state of heaven and earth's qi in that month. Regarding "Jiazhong," the Records of the Grand Historian (Shiji), "Treatise on the Pitch-Pipes," and the Book of Han (Hanshu), "Treatise on Pitch-Pipes and the Calendar," offer explanations to the effect that: by the second month, yang qi is flanking and assisting all things in their generation, enabling dormant life to stir and grow. The "jia" of "Jiazhong" describes yang qi's action of flanking, supporting, and assisting all things as they burst through the bonds of yin qi and surge forth.

How perfectly this accords with the theme of Jingzhe! Jingzhe is precisely the season when yang qi surges, flanking and assisting all things as they break through the gloom, awakening and growing. The sound of "Jiazhong" is the sonic expression of this "yang qi flanking and assisting the generation of all things." When we say that Jingzhe's "sound" is Jiazhong, we mean: the rhythm of heaven and earth's qi at Jingzhe -- surging, assisting, generative -- resonates precisely with the frequency of the Jiazhong pitch-pipe.

Going deeper, "Jiazhong," assigned to the second month, sits between Taicu (first month) and Guxian (third month). From Huangzhong (eleventh month, yang qi first born) through Dalv and Taicu to Jiazhong, yang qi has grown steadily. The position of "Jiazhong" is precisely the critical node at which yang qi has grown strong enough to "flank and assist" the full-scale generation of all things -- fully consistent with the second month's Dazhuang hexagram (four yang lines ascendant) in the Twelve Waxing-and-Waning Hexagrams. Pitch-pipe and hexagram, from different perspectives (sound and number-image), together fix the essence of Jingzhe: "yang qi ascendant, flanking and assisting all things."

III. The Theory of "Testing the Qi": The Qi of Heaven and Earth in the Pitch-Pipes

The ancients had an extraordinary practice related to "the unity of pitch-pipes and calendar" called "testing the qi" (hou qi).

In this practice, the ancients believed that if pitch-pipes corresponding to the twelve months were buried in a sealed chamber in a particular manner, with the ash of burned reed membranes (jiafu zhi hui, "catkin ash") placed inside each pipe, then when heaven and earth's qi arrived at a given month, the ash in the pitch-pipe corresponding to that month would be blown out by the "qi." For example, at the winter solstice (eleventh month), the ash in the Huangzhong pipe would stir; at Jingzhe's second month, the ash in the Jiazhong pipe would stir.

This "testing the qi" theory, from today's perspective, lacks scientific foundation and is difficult to reproduce. Yet the conception it reflects is profoundly significant: the ancients believed that heaven and earth's qi was real, flowing, and rhythmic, and that this rhythmic qi could be "sensed" and "measured" through pitch-pipe "instruments." In their imagination, the qi of heaven and earth and the qi of musical pitch were the same thing -- when the qi moved to the second month, it would resonate with the Jiazhong pipe and blow out its ash. This was a grand conception unifying astronomy, calendar, music, and even physical experimentation.

Whether or not the testing of qi could actually work, it vividly embodies the core conviction of Chinese antiquity: the cosmos is an organic whole filled with rhythm and mutual responsiveness. The qi above, the things below, the ash in the pipe, the sound in the ear -- all are penetrated by one and the same "qi." Jingzhe's correspondence with Jiazhong is not an abstract assignment but, in the ancients' eyes, a living, "testable," "sensible" cosmic rhythm.

IV. The Jue Note and Jiazhong: The Two Dimensions of Jingzhe's Sound

We have now encountered two dimensions of Jingzhe in musical tuning: from the perspective of the five notes (gong, shang, jue, zhi, yu), the spring season of Jingzhe corresponds to "jue" (see Chapter Four); from the perspective of the twelve pitch-pipes, Jingzhe's second month corresponds to "Jiazhong." What is the relationship between these two$2

The five notes are assigned from the framework of the "Five Phases": jue = Wood = spring; zhi = Fire = summer; gong = Earth = late summer; shang = Metal = autumn; yu = Water = winter. This fixes the general sonic character of Jingzhe as "spring" and "the virtue of Wood" -- the jue tone is clear and rising, like branches stretching upward, vitality bursting forth.

The twelve pitch-pipes are assigned from the framework of the "twelve months," more finely grained than the five notes: each month receives one pitch-pipe. Jiazhong is assigned to the second month, fixing the sonic character of Jingzhe as the specific period of "mid-spring, second month" -- the qi of Jiazhong, flanking and assisting all things in their generation.

Viewed together, Jingzhe's sound achieves a complete portrait: broadly, it belongs to "jue" (Wood, spring, generation, rising); specifically, it belongs to "Jiazhong" (second month, yang qi flanking and assisting all things). One fixes its "kind" (the Wood of spring), the other its "position" (mid-spring, second month). These two dimensions together compose the precise coordinates of Jingzhe within the music of heaven and earth.

From this we can appreciate how three-dimensional and subtle the ancients' understanding of the solar terms was. They grasped Jingzhe not only through astronomy (ecliptic longitude, stellar phenomena), phenology (peach blossoms, orioles), hexagram imagery (Zhen, Dazhuang), and the Five Phases (the virtue of Wood), but also through musical tuning (jue, Jiazhong). In their cosmos, Jingzhe was not merely visible (blazing peach blossoms) and palpable (the crash of spring thunder) but audible (the sound of Jiazhong). When heaven and earth's qi reached Jingzhe, it played a "Jiazhong" melody -- what a poetic and profound cosmic imagination!

Chapter Fifteen: Dormancy and Awaiting the Moment -- The Great Life Wisdom of the Way of Bending and Stretching

I. "The Dragon and the Snake Hibernate in Order to Preserve Their Lives": The Wisdom of Dormancy

In a solar term whose theme is "startling dormant creatures awake," we naturally celebrate the "startling" (jing) -- the surging of yang qi, the awakening of life. Yet we must equally remember the "dormancy" (zhe) -- the long stage of hiding that precedes awakening. For without winter's "zhe," there can be no Jingzhe's "jing." This chapter is devoted to the wisdom of "zhe" and to that great theme running through Chinese philosophy -- the Way of bending and stretching.

The Xici commentary (Part II) of the Book of Changes offers a supremely incisive discussion that is the core text for understanding the wisdom of "zhe": "The inchworm bends in order to stretch; the dragon and the snake hibernate in order to preserve their lives. To enter the subtlety of righteous principle so as to achieve practical application; to use benefit to secure one's person so as to exalt virtue."

"The inchworm bends in order to stretch" -- the inchworm contracts its body so as to extend itself forward ("xin" is a loan character for "shen," to stretch). "The dragon and the snake hibernate in order to preserve their lives" -- the dragon and the snake lie dormant precisely to preserve their lives. These two metaphors express the profound wisdom of "dormancy" in full: bending is for the sake of stretching; hiding is for the sake of preserving. Dormancy is not passive flight, not the cessation of life, but a far-sighted strategic contraction undertaken for the sake of greater future surging.

This is the deepest double lesson of the Jingzhe solar term. On one hand, Jingzhe's "jing" tells us: when the moment arrives, surge forth (stretch). On the other hand, the "zhe" creatures that Jingzhe rouses teach us through their entire winter of dormancy: before the moment arrives, know how to lie hidden (bend). The dormant creatures are able to surge forth at Jingzhe, full of vitality, precisely because they stored sufficient life force during their winter hibernation. Without this period of "zhe" and nourishing, the "jing" of surging forth would have no foundation.

II. Bending and Stretching: A Dialectical Life Wisdom

"The inchworm bends in order to stretch" -- this sentence reveals the profound dialectical relationship between "bending" (qu) and "stretching" (shen).

In worldly eyes, "bending" (yielding, retreating, lowering one's head) is often seen as weakness, failure, or disgrace, while "stretching" (advancing, striving, holding one's head high) is seen as strength, success, or glory. But the wisdom of the Book of Changes tells us: bending and stretching are not opposites but complementary and causally intertwined. If the inchworm does not first "bend" (contract), it cannot "stretch" (advance) -- its forward motion depends precisely on contraction as its precondition. Likewise, a person who does not know how to "bend" at the appropriate time (to endure, to yield, to build strength) will be unable to "stretch" at the right moment (to surge, to advance, to achieve).

This Way of bending and stretching is illustrated by countless vivid examples in Chinese history. King Goujian of Yue endured hardship, sleeping on brushwood and tasting gall -- this was "bending": he bore humiliation, submitted to servitude, and stored his strength; his ultimate destruction of the state of Wu was "stretching." Han Xin suffered the humiliation of crawling between a ruffian's legs -- this was "bending": he endured a moment's disgrace to preserve his life; his eventual appointment as supreme general and enfeoffment as marquis was "stretching." These are all living embodiments of "the inchworm bends in order to stretch" and "the dragon and the snake hibernate in order to preserve their lives." Their "bending" and "hibernating" were not cowardice but the greatest wisdom -- endurance and nourishment undertaken for the sake of a greater future "stretching" and "surging."

The Most High (Laozi) also offered profound discourse on this. He said: "That which bends shall be preserved whole; that which is crooked shall be made straight; that which is hollow shall be filled; that which is worn shall be renewed" (Daodejing, Chapter 22). This is of one spirit with the Yijing's "the inchworm bends in order to stretch." The Most High also said: "That which is about to contract must first expand; that which is about to weaken must first grow strong... The soft and weak overcome the hard and strong" (Daodejing, Chapter 36). All of this speaks to the dialectical transformation between bending and stretching, strength and weakness, advance and retreat. In the Daoist view, to understand "bending," "softness," and "retreat" is precisely the highest wisdom, for it accords with the fundamental law that "reversal is the movement of the Way."

III. Awaiting the Moment: The Core of Dormancy Is Waiting for the Right Time

The wisdom of "zhe," at its root, is a wisdom of "awaiting the moment" (dai shi) -- waiting for the right time.

What does the dormant creature wait for through the winter$3 It waits for the spring thunder, for the moment when yang qi surges. It will not rashly emerge in the depths of winter -- to do so would mean freezing to death. It lies quietly dormant, nourishing, waiting, until the spring thunder of Jingzhe sounds and the true moment of yang qi's surging arrives, and then it surges forth. This wisdom of "moving when the moment is right" (dai shi er dong) is the most precious lesson that the dormant creature teaches us.

The Book of Changes places supreme importance on "time" (shi). The entire Yijing can be said to be a book about "time" -- when to advance, when to retreat; when to move, when to be still; when to bend, when to stretch. The Qian hexagram speaks of "the hidden dragon -- do not act" (qian long wu yong) -- when the moment has not arrived (the hidden dragon), one must understand "do not act" (refrain from rash action). This is the wisdom of "zhe." It also speaks of "the flying dragon is in the heavens" (fei long zai tian) -- when the moment is ripe (the flying dragon), surge forth and soar. This is the wisdom of "jing." From "the hidden dragon -- do not act" to "the flying dragon is in the heavens" is the complete journey from "zhe" to "jing," from bending to stretching.

Master Meng (Mencius) praised the Master (Confucius) as "the sage of timeliness" (Mencius, "Wan Zhang," Part II), honoring him as one supremely skilled at grasping "time" (shi). A truly wise person knows how to respond most fittingly to each moment -- hibernating when hibernation is called for, rising when rising is called for; waiting when waiting is called for, acting when action is called for. This precise grasp of "time" is the core wisdom that Jingzhe conveys. The dormant creature rises at the sound of thunder, neither too early nor too late, precisely at Jingzhe -- this is the perfect exemplar of "moving when the moment is right."

IV. Dormancy and the Rhythm of Life: The Way of Movement and Stillness Alternating

From the relationship between dormancy and awakening, we can discern a still more universal truth -- the rhythm of life is the alternation of movement and stillness, the cycling of surging and nourishing.

The operation of heaven and earth is never all "movement" nor all "stillness" but the mutual generation of movement and stillness, the endless cycling of the two. Winter favors stillness (dormancy); spring and summer favor movement (growth); autumn favors gathering (harvest). This rhythm of alternation is the fundamental mechanism by which cosmic vitality perpetuates itself. If there were only "movement" without "stillness," vitality would quickly be exhausted. If there were only "stillness" without "movement," life would descend into lifelessness. Only in the mutual generation of movement and stillness, the balance of tension and release, can life continue without end.

The Most High said: "All things arise, and I thereby observe their return. Things proliferate, yet each returns to its root. Returning to the root is called stillness; stillness is called returning to life's mandate" (Daodejing, Chapter 16). All things grow vigorously (movement), and ultimately each returns to its root (stillness). Returning to the root is "stillness," and "stillness" is the return to life's source ("returning to life's mandate," fu ming). In the Most High's view, "stillness" (returning to the root, dormancy) is not the end of life but precisely its "returning to life's mandate" -- the fundamental process by which vitality is re-nourished and renewed. The dormant creature's winter hibernation is precisely this "returning to the root," this "returning to life's mandate" -- in stillness (dormancy) it "returns to life's mandate," nourishing its vitality, and then in the spring thunder of Jingzhe it once again "arises" (surges forth).

This yields a profound life lesson: do not fear "dormancy"; do not disdain "stillness." Life has its "Jingzhe" of surging advance and its "winter" of dormant nourishment. When it is time to surge, rise like the dormant creature at the sound of thunder, giving everything. When it is time to hibernate, rest in dormancy, turn inward, store strength, and await the moment. To be able to move and to be still, to bend and to stretch, balanced in tension and release, with movement and stillness mutually generating -- this is the most complete life wisdom, the one most in accord with the Way of Heaven and the rhythms of life. The Jingzhe solar term, with its two characters "jing" and "zhe," crystallizes precisely this dialectical wisdom of "movement" and "stillness." It reminds us: surging forth is precious, but the dormancy that precedes it is equally indispensable.

Chapter Sixteen: Confucian and Daoist Perspectives Compared -- Two Attitudes toward Life in Jingzhe

I. The Confucian Jingzhe: Strive Vigorously; Examine Oneself with Awe

Confucianism and Daoism are the two great currents of pre-Qin thought. Facing the same solar term of Jingzhe, the two schools share certain understandings yet also exhibit subtle differences. This chapter attempts, through comparison, to reveal more deeply the philosophical content of Jingzhe.

First, the Confucian perspective. The Confucian attitude toward Jingzhe is, at its core, "vigorous striving" (fenfa youwei). Jingzhe's thunder rouses all things and also rouses the human spirit of enterprise. In the Confucian view, one should answer this summons, rise energetically, and engage actively in the year's labor, cultivation, and endeavors. This is of one spirit with the fundamental Confucian principle from the Yijing's Qian hexagram Image commentary: "The movement of Heaven is vigorous; the noble person thereby strives ceaselessly" (tian xing jian, junzi yi ziqiang buxi). The Way of Heaven is vigorous and ceaselessly striving; humans should emulate this by being self-strengthening and ceaselessly active. Jingzhe's surging yang qi and rising of all things provide the celestial mandate for the noble person's "ceaseless striving."

Yet the Confucian "striving" is by no means blind or unrestrained. The two points we discussed earlier are precisely the two constraints that Confucianism places on "striving." First, the Zhen hexagram's "repeated thunder, the noble person is moved to fearful self-examination" -- alongside striving, one must maintain awe and self-reflection. Second, the Dazhuang hexagram's "the noble person does not tread where propriety forbids" -- alongside vigor, one must exercise self-discipline through propriety, refraining from what should not be done. Thus, the Confucian spirit of Jingzhe is a unity of "striving" and "restraint," of "purposeful action" and "self-examination." It both encourages active enterprise and demands that in the course of enterprise one maintains moral self-awareness and the constraints of propriety and righteousness.

This embodies the fundamental Confucian wisdom of the "Mean" (zhongyong). To strive without excess, to advance without transgression, to be vigorous yet observe propriety -- this is a supreme achievement. It requires that at the moment when vitality is most exuberant, one still maintain clarity of mind and propriety of conduct. The Jingzhe season is the very test of this cultivation: when yang qi surges, all things rise, and one's spirits are high, whether one can "not tread where propriety forbids" and "examine oneself with awe" marks the divide between the noble person and the petty.

II. The Daoist Jingzhe: Following Nature, Effortless Yet Leaving Nothing Undone

Now the Daoist perspective. The Daoist attitude toward Jingzhe is, at its core, "following nature" (yin ren ziran).

In the Daoist view, the arrival of Jingzhe, the awakening of dormant creatures, the generation of all things -- all are manifestations of "the Way follows Nature" (dao fa ziran). They occur naturally and spontaneously, needing no human intervention or promotion. The Most High said: "The Way is ever effortless, yet nothing is left undone" (Daodejing, Chapter 37). The Way appears to do nothing (wuwei), yet everything is accomplished (wu bu wei). Spring thunder naturally sounds, yang qi naturally surges, dormant creatures naturally awaken, peach blossoms naturally open -- all of this is the natural operation of "the Way," and humans need not and should not deliberately intervene.

What Daoism admires more is the wisdom represented by the character "zhe" in Jingzhe -- dormancy, guarding stillness, awaiting the moment. The ideas we discussed in the previous chapter -- "the dragon and the snake hibernate in order to preserve their lives," "that which bends shall be preserved whole," "returning to the root is called stillness" -- are all closer to the Daoist temperament. Daoism does not emphasize "vigorous striving" as Confucianism does, but rather "guarding softness and dwelling in stillness" (shou rou chu jing), "attaining to the utmost emptiness, holding firmly to stillness" (zhi xu ji, shou jing du). In the Daoist view, "stillness" is more fundamental than "movement," and "dormancy" is closer to the nature of the Way than "striving."

Does Daoism, then, deny "jing" -- deny striving$4 Not entirely. The Daoist wisdom lies in perceiving that "movement" and "stillness," "jing" and "zhe," are two faces of one reality, mutually transforming. Jingzhe's thunder-"movement" was precisely gestated from winter's "stillness" (the return of one yang, dormant nourishing); and this "movement" will ultimately return to the "stillness" of autumn and winter (all things return to their roots). What Daoism pursues is to follow the natural rhythm of this movement-stillness cycle -- when heaven and earth turn from stillness to movement (Jingzhe), follow the movement; when from movement to stillness (autumn and winter), follow the stillness. No forcing, no rash action; all in accordance with nature. This is the Daoist attitude toward Jingzhe: not to "do" something but to "follow" something -- to follow that life-qi which pervades heaven and earth and operates of its own accord.

III. Common Ground: A Shared Recognition of the Rhythm of the Way of Heaven

Despite their differences in attitude toward Jingzhe, Confucianism and Daoism share profound common ground at a deeper level.

The most fundamental commonality is that both recognize the same truth: human beings should maintain harmony with the rhythm of the Way of Heaven. Whether it is the Confucian "ceaseless striving" (emulating the vigor of the Way of Heaven) or the Daoist "the Way follows Nature" (according with the constancy of the Way of Heaven), both point fundamentally toward "the unity of Heaven and humanity" (tian ren he yi) -- synchronizing human life with the rhythm of heaven and earth. At Jingzhe, when heaven and earth turn from stillness to movement and yang qi surges, Confucianism calls for vigorous purposeful action; Daoism calls for following nature. On the surface, one is "purposeful action" and the other "effortless action," but their shared premise is to "follow" the Way of Heaven and "respond" to the heavenly season. This shared reverence for and accordance with the rhythm of the Way of Heaven is the spiritual bedrock common to both schools.

Second, both value the worth of "dormancy." Confucianism, though it emphasizes striving, also speaks of "the hidden dragon -- do not act" and of "if employed, then act; if set aside, then hide" (Lunyu, "Shu Er") -- the Master himself said that if given office he would put his principles into practice, and if not, he would withdraw. This is precisely the wisdom of "zhe." Daoism goes without saying: "guarding stillness" and "dormancy" are at its very core. Clearly, on the point that "one should hide when hiding is called for, and move when the moment arrives," the two schools are in high agreement. The "Way of bending and stretching" and "mutual generation of movement and stillness" that Jingzhe embodies are life wisdoms acknowledged by both.

Third, both emphasize maintaining a certain inner "composure" amid "movement." Confucianism speaks of "thunder startles for a hundred li, yet he does not lose the ladle and libation" -- constancy in the face of upheaval. Daoism speaks of "attaining to the utmost emptiness, holding firmly to stillness" and "heaviness is the root of lightness; stillness is the sovereign of restlessness" (Daodejing, Chapter 26) -- conquering movement through stillness, governing lightness through gravity. Both schools recognize that true strength lies not in blind agitation but in holding stillness within movement, composure within striving. This wisdom of "cultivating both movement and stillness" is the profound admonition that both Confucianism and Daoism offer in the face of Jingzhe, this solar term of "movement."

IV. The Unity of "Jing" and "Zhe": A Rounded Wisdom That Transcends Confucianism and Daoism

If we view the wisdom of both schools together, we arrive at a more rounded understanding of Jingzhe -- one that transcends the surface differences between Confucianism and Daoism and points directly to the natural rhythm of life.

The name "Jingzhe" itself contains two seemingly opposed aspects: "jing" (movement, surging) and "zhe" (stillness, dormancy). Confucianism excels at elucidating the wisdom of "jing" -- vigorous striving, ceaseless self-strengthening (supplemented by fearful self-examination and non-transgression of propriety). Daoism excels at elucidating the wisdom of "zhe" -- guarding stillness and dormancy, following nature, awaiting the moment. Each school holds one end, yet perfectly complements the other, together constituting a complete interpretation of the Jingzhe solar term.

Truly rounded life wisdom should be the unity of "jing" and "zhe": knowing how to rise like spring thunder when it is time to surge (the Confucian "jing"), and knowing how to rest like a dormant creature when it is time to hide (the Daoist "zhe"); maintaining restraint and awe within movement, and nourishing vitality and latent power within stillness. This state of "jing-zhe unity," of "movement-stillness roundedness," transcends the opposition of "purposeful" and "effortless," reaching a freedom that follows the Way of Heaven and moves with ease between exertion and repose.

This is perhaps the deepest lesson that the Jingzhe solar term leaves us: life is neither unceasing striving (which leads to exhaustion) nor unbroken dormancy (which leads to withering), but the dialectical unity of striving and dormancy, the cycling back and forth of "jing" and "zhe." Those who understand this truth can rise with vigor at life's "Jingzhe" and rest with equanimity in life's "winter" -- movement and stillness generating each other, bending and stretching in due measure, thus living out a life of fullness that accords with the Way of Heaven and perpetuates itself without end. Confucianism and Daoism, from their respective vantage points, converge on this rounded vision.

Chapter Seventeen: A Philosophical Chapter on "Why" -- How Do All Things Know Thunder and Rise$5

I. The Ultimate Question: How Does the Dormant Creature "Know" It Is Time to Awaken$6

As this article draws toward its close, let us return to the most profound, most fundamental question raised in the introduction: How does the dormant creature "know" that spring thunder has sounded and it is time to awaken$7

This question appears simple but in fact touches upon the most subtle core of the cosmology of Heaven-humanity unity. A creature buried several feet underground can neither hear the thunder nor see the sunlight, and cannot directly perceive changes in surface temperature. By what means does it "know" that the season has turned and life should begin again$8 Why do tens of thousands of dormant creatures awaken at roughly the same time (around Jingzhe), as though between them and between them and heaven and earth there existed some mysterious "agreement"$9

The ancients, too, pondered this question deeply. And the answer they gave was not couched in terms of mechanical causation (such as "rising soil temperature stimulates the nervous system") but appealed to a grander, more profound vision -- Heaven-humanity resonance, all things as one qi. In the ancients' view, the reason a dormant creature can "know" it is time to awaken is that it shares with the entire cosmos the same "qi." When this qi reaches Jingzhe and yang qi surges, the portion of "qi" within the dormant creature resonates with heaven and earth's qi, and thus the creature "naturally" awakens. It is not "notified" by external thunder but "awakened" by the internal life-qi that shares its source with heaven and earth.

II. "Like Sounds Respond to Each Other; Like Qi Seeks Its Kind": The Cosmos of Resonance

To understand this "resonance," we must invoke a supremely incisive passage from the Wenyan commentary on the Qian hexagram of the Book of Changes: "Like sounds respond to each other; like qi seeks its kind. Water flows toward what is wet; fire approaches what is dry; clouds follow the dragon; winds follow the tiger; when the sage arises, all things are seen clearly. What is rooted in heaven cleaves to what is above; what is rooted in earth cleaves to what is below. Each follows its kind."

"Like sounds respond to each other; like qi seeks its kind" (tong sheng xiang ying, tong qi xiang qiu). Identical sounds resonate with each other; identical qi is mutually attracted. These eight characters are the core formulation of the Chinese cosmology of "resonance." They reveal a fundamental conviction: among all things in the cosmos, whatever is of the same kind, the same qi, will resonate with and respond to each other. "Water flows toward what is wet; fire approaches what is dry" -- water flows to damp places, fire burns toward dry ones. "Clouds follow the dragon; winds follow the tiger" -- clouds rise with the dragon, winds blow with the tiger. All are manifestations of "like qi seeks its kind" and "each follows its kind."

Applying this principle to the awakening of dormant creatures, everything becomes clear: within the dormant creature there is "yang qi" (life-qi), and at Jingzhe heaven and earth's yang qi surges forth. The yang qi of heaven and earth and the yang qi within the dormant creature are "like qi." And so, "like qi seeks its kind" -- when heaven and earth's yang qi stirs, the yang qi within the dormant creature resonates and stirs in turn, and the creature awakens. This is not the physical stimulus of thunder but the resonant communion of "qi." Just as plucking one string of a lute causes another string tuned to the same pitch to vibrate sympathetically (a physical illustration of "like sounds respond to each other"), when heaven and earth's yang qi is "plucked" (surges forth), the identical yang qi within the dormant creature spontaneously "resonates" (awakens).

This is the ancients' fundamental answer to "How do all things know thunder and rise$10": not because of external "knowing" (cognition, perception) but because of internal "responding" (resonance, sympathetic vibration). The dormant creature does not need to "know" anything; it only needs to "respond" -- to respond to the qi of heaven and earth that shares its source. In this sense, the awakening of the dormant creature, the blooming of the peach, the singing of the oriole, and the farmer's going to the fields are essentially the same phenomenon -- all are manifestations of the moment when heaven and earth's yang qi surges and all things (including humans) respond in accordance with "like qi seeks its kind." Jingzhe is the total eruption of this grand "cosmic resonance."

III. All Things Are One: The Foundation of Resonance

But we must press one layer further: Why can all things "seek their kind" and resonate with one another$11 What is the foundation of this resonance$12

The answer lies in a still more fundamental conviction -- all things are one body, all things are one qi. In the ancients' view (especially the Daoists'), all things between heaven and earth are ultimately constituted by the same "qi." Master Zhuang said: "What pervades all under heaven is one qi, nothing more" (Zhuangzi, "Zhi Bei You"). Heaven is this qi; earth is this qi; humans are this qi; and the dormant creature is this qi. All things differ infinitely in form, but in essence they are merely different gatherings and dispersals, different configurations, of the same qi.

Precisely because all things are fundamentally "one qi," they can resonate with and respond to each other. This is like the water of a single vast ocean: though divided into innumerable waves, it is at bottom the same water. The ripple in one place naturally propagates to another. The "ripple" of heaven and earth's qi at Jingzhe (the surging of yang qi) naturally propagates and resonates with the dormant creature, as one part of "the same qi," causing it to awaken. "All things are one qi" is the ontological foundation that makes resonance possible.

This vision of "all things are one body" is not merely a cosmology but a profound life experience and ethical horizon. Master Zhuang said: "Heaven and earth were born together with me, and all things are one with me" (Zhuangzi, "Qi Wu Lun"). If we truly apprehend that we and all things of heaven and earth are fundamentally "one qi" and "one body," then the awakening of dormant creatures at Jingzhe, the blooming of peach blossoms, are no longer natural phenomena "external to me" but part of the manifestation of "my own" vitality. The yang qi rising within your body and the yang qi rising within the dormant creature and the yang qi surging between heaven and earth are one and the same process. In this sense, Jingzhe is not something happening "outside" you but the magnificent moment when "you," as one member of heaven, earth, and all things, awaken and surge forth together with everything else.

IV. Bending and Stretching, Back and Forth; Resonance without End: The Cosmic Rhythm of the Xici Commentary

Finally, let us return to that passage on "bending and stretching" in the Xici commentary (Part II), placing it within the cosmology of "resonance" for a deeper appreciation.

Immediately following "the inchworm bends in order to stretch; the dragon and the snake hibernate in order to preserve their lives," the Xici continues: "The sun departs and the moon comes; the moon departs and the sun comes. Sun and moon push each other onward, and brightness is born. Cold departs and warmth comes; warmth departs and cold comes. Cold and warmth push each other onward, and the year is completed. That which departs is bending; that which comes is stretching. Bending and stretching resonate with each other, and benefit is born."

This passage elevates the wisdom of "bending and stretching" to the plane of cosmic rhythm. The departure of the sun and arrival of the moon, the departure of cold and arrival of warmth -- this is the eternal "bending-and-stretching back-and-forth" of the cosmos. "That which departs is bending; that which comes is stretching." "Bending and stretching resonate with each other, and benefit is born" (qu xin xiang gan er li sheng yan) -- bending and stretching resonate with and propel each other, and thereby the benefit (vitality, utility) of all things is generated.

What a grand cosmic vision! The entire operation of the cosmos is a never-ceasing "resonance of bending and stretching": sun and moon push each other in their bending-and-stretching and generate brightness; cold and warmth push each other in their bending-and-stretching and complete the year. And Jingzhe is a critical node in this grand "resonance of bending and stretching" -- it is the turning point of "cold departing and warmth arriving," of "bending reaching its extreme and turning to stretching." Winter's "bending" (dormancy, cold departing) begins at Jingzhe to turn toward spring's "stretching" (surging, warmth arriving). The dormant creature's "bending" (dormancy) begins at Jingzhe to turn toward the "stretching" of awakening (surging forth). In the resonance and mutual propulsion between this "bending" and this "stretching," the burgeoning vitality of the Jingzhe season is generated ("benefit is born").

With this, we have a complete and profound answer to the ultimate question "How do all things know thunder and rise$13": All things can awaken together at Jingzhe because all things between heaven and earth are fundamentally "one qi" (all things are one body), and therefore can "seek their kind" (resonate with each other). This resonance, in turn, follows the cosmic rhythm of "bending and stretching resonating with each other" -- winter's "bending" (dormancy) resonates with spring's "stretching" (surging), and thus all things at the turning point of bending and stretching (Jingzhe) turn together from bending to stretching, from dormancy to awakening, from stillness to movement. The dormant creature does not need to "know"; it only needs to "resonate." And the reason it can resonate is that it and all things of heaven and earth are fundamentally one body, fundamentally one qi -- the same ceaselessly generating, ceaselessly bending-and-stretching cosmic qi. This is the deepest cosmic truth that the ancients revealed to us about Jingzhe.

Conclusion: Jingzhe's Thunder -- A Summons from Heaven and Earth to Life

I. Looking Back: What Have We Heard$14

Through the detailed analysis of the preceding seventeen chapters, we have explored the solar term "Jingzhe" from multiple perspectives -- etymology, history, astronomy, calendrical science, phenology, hexagram imagery, the Five Phases, agriculture, health cultivation, ritual, mythology, musical tuning, and philosophy.

We examined its original name "Qizhe" and the historical affair of its renaming to "Jingzhe" to avoid the taboo name of Emperor Jing (Liu Qi) of the Han, and thereby savored the different nuances embedded in the single-character distinction between "qi" (gentle opening) and "jing" (thunderous awakening). We contemplated the two characters "jing" and "zhe" -- "jing" is Heaven's rousing of all things; "zhe" is life's inward nourishment. United, they mark the great threshold at which life transitions from quiescent dormancy to vigorous action.

We hearkened to the ancient echo of "the sovereign emerges from Zhen" in the Book of Changes' Zhen hexagram -- Jingzhe's thunder is the beginning of cosmic life, the activation of creative force. We inscribed in memory the admonition of "repeated thunder, the noble person is moved to fearful self-examination" -- before heavenly majesty, be awed and self-reflective. We discerned the vigorous spectacle of the Dazhuang hexagram's "Thunder above Heaven," and kept firmly in mind the profound wisdom of "the noble person does not tread where propriety forbids" -- amid vigor there must be restraint; strength must be bound by rectitude and propriety.

We savored the splendor of "lovely is the peach tree, ablaze are its blossoms," listened to the oriole's melodious song of spring, and penetrated the cosmic mystery of yin-yang transmutation behind "hawks transform into pigeons." We traced the mythological faces of the thunder god Fenglong, Lei Gong, and the spring god Goumang; we listened to the sound of "Jiazhong," the pitch-pipe assigned to Jingzhe; and we appreciated the grand imagination of "the unity of pitch-pipes and calendar," in which all of heaven and earth possesses rhythm.

And most importantly, we pursued the ultimate question -- How do all things "know" thunder and rise$15 -- and from the cosmology of "like sounds respond to each other; like qi seeks its kind," "all things are one body and one qi," and "bending and stretching resonate with each other," we found a profound answer: the awakening of all things is not external cognition but internal resonance; not being "notified" by the sound of thunder but being "awakened" by the life-qi that shares its source with heaven and earth.

II. Jingzhe's Thunder: An Eternal Metaphor

If Lixia (Beginning of Summer) is a doorway, then Jingzhe is a thunderclap -- a clap of spring thunder that shatters the silence and rouses life to wakefulness. This thunderclap is an eternal metaphor.

It is a metaphor for every moment of "awakening." In each of our lives, there are such "Jingzhe" moments -- some instant, some "thunderclap," that rouses our dormant ambition, dormant potential, dormant vitality. Perhaps it is a single sentence, a book, an encounter that, like spring thunder, shakes the heart and jolts us from a drifting "dormancy" into vigorous action. Jingzhe reminds us: listen for that "thunderclap" in your life, and have the courage to answer its summons.

It is also a metaphor for the value of "dormancy." The dormant creatures that Jingzhe rouses stored their strength through an entire winter of hibernation, and only thereby could they surge forth at the spring thunder. This tells us: the dormancy that precedes the rising is not wasted, not failure, but necessary nourishment. Life's valleys, adversities, and periods of hidden preparation are like the creature's winter sleep -- they are storing energy for the future rising. "The dragon and the snake hibernate in order to preserve their lives" -- only those who understand dormancy understand the true rising.

More than anything, it is a metaphor for the wisdom of "bending and stretching." Jingzhe is precisely the threshold at which "bending" (dormancy) turns to "stretching" (surging). It tells us: life has its bendings and its stretchings, its hiding and its moving. The key lies in grasping "time" -- bending when bending is called for, stretching when stretching is called for; dormant when dormancy is called for, and roused when rousing is called for. To be able to bend and to stretch, to hide and to move, with movement and stillness generating each other and tension and release in balance -- this is a life in accord with the Way of Heaven, a life of roundedness and fullness.

III. A Final Inquiry: Can We Still Hear That Thunder$16

At the close of this essay, let us return to the initial question: Why do we need to understand Jingzhe anew$17

Because in modern life, we can no longer hear that "thunder." We live in climate-controlled rooms, no longer feeling the turn of the seasons. We are surrounded by floods of information and entertainment, our spirits grown numb and noisy, no longer able to "examine ourselves with awe" at a clap of spring thunder, no longer able to feel the trembling of life before a tree of peach blossoms. We are like creatures in perpetual hibernation, yet we can no longer wait for or hear the spring thunder that would rouse us. We have lost our connection to the rhythms of heaven and earth, and with it the sensitivity and reverence we once felt at the awakening of life.

To understand Jingzhe anew is not to return to the way of life of the pre-Qin era, but to reawaken within ourselves that sensitivity and awe before life, before heaven and earth. When Jingzhe arrives, try stepping outside, listening to a real clap of spring thunder, gazing at a tree of peach blossoms just opening, feeling in the air that surging, generative breath. In these simple perceptions, you may touch the experience of Heaven-humanity mutual responsiveness that the ancients once knew -- and you will discover that the spring thunder that rouses the dormant creatures is also rousing you; that the yang qi which brings forth the peach blossoms is also rising within you. You are not an isolated, numbed individual; you are one among billions of awakening lives between heaven and earth, sharing with the dormant creature, the peach blossom, and the oriole the same ceaseless, bending-and-stretching cosmic qi.

The Book of Changes says: "The sovereign emerges from Zhen." That creative force which rouses all things issues from the Zhen trigram, from the spring thunder. And what it rouses has never been only the creatures underground -- it rouses all sleeping life between heaven and earth, including you and including me.

That clap of spring thunder sounds anew, year after year. It asks every sleeping life:

Have you awakened$18
