Chapter 4: The Month of Midsummer in the Liji's "Monthly Ordinances": A Cosmic Picture in Which the Virtue of Fire Reaches Its Height

In the system of the "Monthly Ordinances" (月令) chapter of the Liji, the year is divided into early, mid-, and late months of each season—"meng," "zhong," and "ji" (孟、仲、季)—for a total of twelve months. Mangzhong belongs to the month of midsummer (仲夏, the fifth month, the wu month). It is worth particular note that Mangzhong and Xiazhi both fall within the month of midsummer. Though these two solar terms share the same month, their character differs greatly—Xiazhi is centered on "arrival" and "culmination" (zhi and ji: yang qi reaching its peak, the day at its longest), whereas Mangzhong is centered on "busyness" and "sowing" (mang and zhong: farm labor at its most intense, harvesting and sowing interwoven). Grasping this point is essential to understanding the distinctive character of Mangzhong, and a dedicated chapter below will analyze it further.

The "Monthly Ordinances" of the Liji (its content is highly consistent with the "Record of Midsummer" 仲夏紀 in the Lüshi Chunqiu 呂氏春秋, Spring and Autumn Annals of Lü Buwei; scholars largely agree the two share a common origin) sketches out a complete cosmic picture for the month of midsummer. This picture is not a scattering of isolated notes, but a precise system of correspondences, layer upon layer, link upon link. Let us unfold it one piece at a time.

II. The Full Picture of Five-Phases Correspondence: Fire, South, Red, Zhi, Seven

The "Monthly Ordinances" records the following concerning the Five-Phases attributes of the month of midsummer:

"In the month of midsummer... its days are bing and ding; its sovereign is the Fiery Sovereign; its spirit is Zhurong; its creatures are the feathered; its note is zhi; its number is seven; its flavor is bitter; its scent is scorched. Its sacrifice is to the stove, and in offering, the lungs come first" (仲夏之月……其日丙丁，其帝炎帝，其神祝融，其虫羽，其音徵，其数七，其味苦，其臭焦。其祀灶，祭先肺).

This passage constructs an extraordinarily precise system of cosmic correspondence, continuous in spirit with that of the month of early summer, both belonging to the virtue of Fire. Let us examine each element in turn:

"Its days are bing and ding"—the month of midsummer corresponds to bing and ding among the Ten Heavenly Stems (天干). The ten stems are matched to the Five Phases: jia and yi belong to Wood (spring); bing and ding belong to Fire (summer); wu and ji belong to Earth (late summer / the center); geng and xin belong to Metal (autumn); ren and gui belong to Water (winter). The wu month, in which Mangzhong falls, is matched with the stems bing and ding—precisely the moment when the virtue of Fire is at its fullest. "Bing" carries the sense of brightness, of radiant illumination; "ding" carries the sense of robustness, of the myriad things standing full-grown and strong. The Fire of bing and ding is a Fire of blazing brightness and robust force, precisely matching the character of Mangzhong, in which yang qi is at its fullest.

"Its sovereign is the Fiery Sovereign"—the presiding sovereign of the month of midsummer is the Fiery Sovereign (炎帝, Yandi). The Fiery Sovereign is Shennong, the high-antiquity sovereign of the virtue of Fire, and also the god of agriculture. Mangzhong is the month of the busiest farm labor, and its presiding sovereign is precisely Shennong the Fiery Sovereign, who taught the people to sow and reap—how exquisite this correspondence is! The Fiery Sovereign both governs the virtue of Fire and presides over agriculture, matching perfectly the dual character of Mangzhong: "the virtue of Fire at its height" together with "farm labor at its busiest." Among all the solar terms, none embodies more fully than Mangzhong the Fiery Sovereign's dual identity as both "sovereign of the virtue of Fire" and "forebear of agriculture."

"Its spirit is Zhurong"—the assisting spirit of the month of midsummer is Zhurong (祝融), the high-antiquity fire god. The "Classic of the Regions Beyond the Seas: South" (海外南經) of the Shanhaijing (山海經, Classic of Mountains and Seas) records: "In the south is Zhurong, of beast's body and human face, riding upon two dragons" (南方祝融，兽身人面，乘两龙). Zhurong, in the body of the fire god, assists the Fiery Sovereign, governing the south and the summer. The Sovereign sets the great direction, and the spirit Zhurong administers the concrete execution—the hierarchy of governance in Heaven mirrors precisely the political structure of the human world.

"Its creatures are the feathered"—the representative category of creature for the month of midsummer is the "feathered creatures" (羽虫), that is, birds. The ancients divided animals into five categories: scaled creatures (fish, matched to spring), feathered creatures (birds, matched to summer), the naked/hairless creature (humankind, matched to the center), furred creatures (beasts, matched to autumn), and shelled creatures (matched to winter). Birds are matched to summer, first because bird activity and birdsong are most abundant in summer, and second because birds fly through the sky, embodying an image of "rising," which accords with Fire's nature of blazing upward. And among the three phenological markers of Mangzhong, both "the shrike begins to cry" and "the mockingbird falls silent" concern birds—the matching of feathered creatures finds vivid confirmation in the phenology of Mangzhong.

"Its note is zhi"—the musical note of the month of midsummer is "zhi" (徵). Among the five notes (gong, shang, jue, zhi, yu — 宮商角徵羽), the zhi note is high, stirring, and fervent, its tonal quality corresponding to the intensity of Fire. The ancients believed that the vibrational frequency of the qi of Heaven and Earth in midsummer resonated with the note zhi. This is a bold imaginative leap that draws acoustics into cosmology—between Heaven and Earth there exists a "resonance" that transcends mere matter, and the resonant note of summer is the stirring zhi.

"Its number is seven"—the numerological correspondence of the month of midsummer is seven. In the ancients' numerology, one and six belong to Water, two and seven belong to Fire, three and eight belong to Wood, four and nine belong to Metal, and five and ten belong to Earth. Seven belongs to Fire, hence it is matched to summer. This system of correspondence between numbers and the Five Phases has extremely ancient roots, perhaps connected to the tradition of the Hetu (河圖, "River Chart") and Luoshu (洛書, "Luo Writing").

"Its flavor is bitter"—the flavor of the month of midsummer is bitter. The five flavors are matched to the Five Phases: sour belongs to Wood (spring), bitter belongs to Fire (summer), sweet belongs to Earth (late summer), pungent belongs to Metal (autumn), and salty belongs to Water (winter). Why should bitterness belong to Fire$24 One explanation holds that bitter things are generally able to clear heat and reduce fire, so the bitterness of flavor counteracts the fullness of fire; another holds that Fire's nature is to blaze upward and to dry, and dryness at its extreme gives rise to bitterness. During Mangzhong, when the weather is hot, the ancients ate bitter foods (such as bitter melon and bitter greens) to clear the heart and reduce fire—precisely in accord with the health-preserving logic of "bitterness belongs to Fire."

"Its scent is scorched"—the scent of the month of midsummer is scorched. "Scorched" is the odor of a thing burnt by fire, directly connected to summer's belonging to Fire. Among the five scents (goaty, scorched, fragrant, fishy, rotten — 膻焦香腥朽), the scorched scent carries the strongest sense of "heat," matching the blazing heat of high summer.

"Its sacrifice is to the stove, and in offering, the lungs come first"—in the month of midsummer, sacrifice is made to the stove god, and in the offering, the lungs are presented first. The stove is the place where fire is used; to sacrifice to the stove in summer, to honor fire with fire, is a logic consistent throughout. Presenting the lungs first reflects one pre-Qin theory of the correspondence between the five internal organs and the Five Phases (the "Monthly Ordinances" matches the lungs to summer, differing from the later medical tradition that matches the heart to Fire); the underlying logic is a correspondence between the organs of the body and the cosmic level.

III. South as Direction, Red as Color: The Son of Heaven's Conduct in Midsummer

The "Monthly Ordinances" also prescribes the conduct of the Son of Heaven during the month of midsummer:

"The Son of Heaven dwells in the Hall of Light's Great Ancestral Chamber, rides in the vermilion carriage, drives the bay-red horses, bears the red banner, wears vermilion robes, wears red jade, eats beans and fowl, and uses vessels that are tall and coarse" (天子居明堂太庙，乘朱路，驾赤骝，载赤旗，衣朱衣，服赤玉，食菽与鸡，其器高以粗).

In midsummer, the Son of Heaven is to dwell in the main chamber of the Hall of Light ("the Great Ancestral Chamber of the Hall of Light," that is, the south-facing main hall), to ride in a red carriage, to drive red horses, to fly a red banner, to wear red robes, to wear red jade, to eat beans and chicken, and to use vessels that are tall and coarse.

Why red$25 Because summer belongs to Fire, and the color of Fire is red; the direction of summer is south, and the south-facing main chamber of the Hall of Light faces directly toward the south. As the intermediary between Heaven and humanity, everything about the Son of Heaven's conduct must remain synchronized with the cosmic law governing the season. Wearing red, riding in red—these are not matters of aesthetic preference, but ways of resonating with the "virtue of Fire" that governs Heaven and Earth at this time, ensuring harmony between Heaven and humanity. Mangzhong falls squarely within midsummer, and this crimson attire of the Son of Heaven is precisely the solemn projection, at the level of ritual propriety in the human world, of Mangzhong's "virtue of Fire at its height."

"Eats beans and fowl"—beans belong to the category of legumes, and the chicken belongs to the feathered creatures, both corresponding to the Five Phases of summer. "Uses vessels that are tall and coarse"—Fire's nature is to blaze upward, so the vessels should be tall; the things of summer are robust and full, so the vessels should be coarse. Even the form of implements is an expression, at the material level, of Heaven's Way. All of this points toward one core idea: human conduct—especially that of the Son of Heaven—must correspond seamlessly to Heaven's Way, without deviating for even an instant.

IV. The Governmental Ordinances of Midsummer: The Way of Restraint, Stilling Sound and Sensual Pleasure, Settling Heart and Qi

The "Monthly Ordinances" contains an ordinance for the month of midsummer laden with deep significance:

"In this month, order the music masters to repair the hand-drums, small drums, and drums... In this month, the day reaches its longest, yin and yang contend, and life and death are divided. The noble person fasts and purifies himself; in his dwelling he must keep his body covered, must not be impetuous, must still sound and sensual pleasure, must not indulge, must lighten his flavors, must not seek rich blending, must moderate his cravings and desires, must settle his heart and qi; the hundred officials attend quietly to their affairs and impose no punishments, so as to settle that which the tranquil yin is bringing to completion" (是月也，命乐师修鞀鞞鼓……是月也，日长至，阴阳争，死生分。君子齐戒，处必掩身，毋躁，止声色，毋或进，薄滋味，毋致和，节嗜欲，定心气，百官静事毋刑，以定晏阴之所成).

This passage is of great importance and calls for careful interpretation. "The day reaches its longest, yin and yang contend, and life and death are divided"—the day reaches its longest point (referring to Xiazhi, which shares a month with Mangzhong), and the two qi of yin and yang are contending fiercely; life and death are decided at this juncture. At this critical point where yin and yang contend, the "Monthly Ordinances" requires the noble person to fast and purify himself, to keep his body covered in his dwelling ("yan shen," 掩身), not to be impetuous ("wu zao," 毋躁), to still sound and sensual pleasure ("zhi sheng se," 止声色), to lighten his flavors ("bo ziwei," 薄滋味), to moderate his cravings and desires ("jie shiyu," 节嗜欲), to settle his heart and qi ("ding xinqi," 定心气), and for the hundred officials to attend to their affairs quietly and impose no punishments—all of this in order to "settle that which the tranquil yin is bringing to completion," that is, to steady the faint yin that has only just begun to sprout, so that it may come to completion normally.

Herein lies the most profound wisdom of the Mangzhong solar term. In midsummer, when yang qi is at its fullest and one would expect the most exuberant self-expression, the "Monthly Ordinances" instead repeatedly demands restraint, moderation, quietude, and settled composure. Why$26 Because the ancients perceived that it is precisely at the moment when yang qi is at its fullest that the one thread of yin qi of the utmost importance ("the tranquil yin," 晏阴) is beginning to sprout. This thread of faint yin is exceedingly fragile and requires careful nurturing; it must not be disturbed or throttled by the exuberant yang. If a person indulges in sound and sensual pleasure and acts impetuously and willfully at this time, they will only reinforce the excess of yang and injure the faint yin, disrupting the rhythm of Heaven's Way as it turns from yin to yang and back again.

This is precisely the expression, at the level of health cultivation and governmental ordinance, of the Gou hexagram's "first stirring of yin." The idea of "guarding against the subtle before it grows," to be discussed in detail below, has already been foreshadowed here—at the height of yang, one must reverently guard the newly born yin; at the moment of greatest fullness, one must maintain a heart of restraint. The busyness of Mangzhong is a busyness of the body; the quietude of Mangzhong is a quietude of the heart. Busyness and quietude, outward motion and inward settledness, are precisely the deepest dialectic of the Mangzhong solar term.

V. Why Does the "Monthly Ordinances" Construct So Precise a System of Correspondence$27

Reflecting on all of this, we cannot help but ask: why does the "Monthly Ordinances" devote such extensive space to constructing this precise system in which stars, heavenly stems, sovereigns and spirits, creatures and notes, flavors and scents, and sacrificial rites all correspond to one another without exception$28

The answer lies in the fundamental impulse of pre-Qin thought toward "a single thread running through all" (一以贯之). The Master said: "My Way is threaded through by one single thing" (吾道一以贯之; Analects, "Li Ren"). This is not merely an ethical principle, but a cosmological conviction—though the myriad things of Heaven and Earth differ vastly from one another, a single, unified law runs through them all. The system of cosmic correspondence in the "Monthly Ordinances" is precisely the concrete unfolding of this conviction: the stars above, the things below, the organs of the human body, the flavors of food, the notes of sound—all are governed by that same single force, the virtue of Fire.

Furthermore, this system is not merely epistemological but practical. It tells rulers and people alike: in this particular season of midsummer, what should and should not be done. The "busyness" of Mangzhong's farm labor and the "quietude" of the "Monthly Ordinances"' heart and qi seem contradictory, yet in fact they are unified under the fundamental principle of "according with Heaven and responding to the season" (顺天应时)—giving one's utmost effort to the farm labor that demands busyness, and carefully guarding the heart and qi that demand quietude: both are devout compliance with Heaven's Way.
