The Return of First Yang: The Heart of Heaven and Earth at the Winter Solstice and the Origin of the New Year
This article offers a profoundly detailed interpretation of the Winter Solstice among the Twenty-Four Solar Terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical calendrics. It reveals the cosmic pivot of 'yin at its extreme giving birth to yang, the return of first yang, and the beholding of heaven and earth's heart,' examines the rites of the Round Mound sacrifice to Heaven, the origin of the calendar epoch at the month of Zi, and the foundational note of the Yellow Bell pitch-pipe, guiding you through the ancient wisdom by which our forebears discerned the generative heart of heaven and earth amid the deepest darkness.
Chapter Three: The Month of Midwinter in the Monthly Ordinances of the Record of Rites: A Cosmic Tableau of Water's Virtue at Its Extreme
I. The Astronomical Positioning of Midwinter
Among all pre-Qin texts, the most systematic description of the Winter Solstice and its month of midwinter is found in the "Monthly Ordinances" (Yueling) of the Record of Rites (Liji) (whose content closely parallels the "Midwinter" section of the Lushi Chunqiu; scholars generally consider them to share a common source). The Monthly Ordinances paint a complete cosmic tableau for midwinter. Let us analyze it passage by passage.
The Monthly Ordinances state: "In the month of midwinter, the sun is in the Dipper (Dou); at dusk, the Eastern Wall (Dongbi) culminates; at dawn, the Chariot-Board (Zhen) culminates."
The sun is in the Dipper -- the sun has moved to the position of the Dou asterism (the Southern Dipper, in present-day Sagittarius). At dusk, the Eastern Wall culminates -- the Bi asterism (in present-day Pegasus) is due south at twilight. At dawn, the Chariot-Board culminates -- the Zhen asterism (in present-day Corvus) is due south at first light. Through these three coordinates -- the sun's position, the dusk-culminating star, and the dawn-culminating star -- the season of midwinter is precisely fixed.
II. The Complete System of Five Phase Correspondences
Immediately after, the Monthly Ordinances describe the Five Phase attributes of midwinter:
"Its days are ren and gui; its sovereign is Zhuanxu; its spirit is Xuanming; its creatures are the shelled; its note is yu; its number is six; its flavor is salty; its odor is that of decay; its sacrifice is to the paths; the offering begins with the kidneys."
This passage constructs an extraordinarily precise system of cosmic correspondences, each item aligned with "Water's virtue." Let us examine each in depth:
"Its days are ren and gui" -- the month of midwinter corresponds to the Heavenly Stems ren and gui. In the pairing of the ten Heavenly Stems with the Five Phases: jia and yi belong to Wood (spring), bing and ding to Fire (summer), wu and ji to Earth (center), geng and xin to Metal (autumn), ren and gui to Water (winter). Ren and gui belong to Water, hence they are paired with winter. This system links time (Heavenly Stems) with elemental qualities (Five Phases) and forms the basic framework of pre-Qin cosmology.
"Its sovereign is Zhuanxu" -- the presiding deity of midwinter is Zhuanxu, one of the Five Sovereigns of high antiquity, assigned to "Water's virtue." This relates to the system pairing the Five Phases with the Five Sovereigns: Taihao presides over spring (Wood), the Flame Sovereign (Yandi) over summer (Fire), the Yellow Sovereign (Huangdi) over the center (Earth), Shaohao over autumn (Metal), and Zhuanxu over winter (Water). Zhuanxu's dominion over the north and winter through Water's virtue perfectly accords with the season of extreme yin in which the Winter Solstice falls.
"Its spirit is Xuanming" -- the assistant spirit of midwinter is Xuanming. "Xuan" means dark, deep, remote; "ming" means dim, obscure. The very name conveys winter's qualities of depth, darkness, and hiddenness. Xuanming is the spirit of water and winter, governing the north and winter. Why is the assistant spirit so darkly named$28 Because the Winter Solstice is the darkest, most yin-laden season of the year, and Xuanming's "darkness" and "obscurity" are its portrait.
Why are both a "sovereign" and a "spirit" needed$29 This reflects the core principle of pre-Qin political philosophy: governance requires a hierarchy of roles. The sovereign is the supreme director who sets the course; the spirit is the executor who carries out the sovereign's will. So it is in heaven; so it is among men. The Son of Heaven is the human world's "sovereign," and the officials are the human world's "spirits." Through this correspondence between heaven and human affairs, the Monthly Ordinances provide cosmological legitimacy for the political order of the human world.
"Its creatures are the shelled" -- the representative creature-category of midwinter is "shelled creatures" (jie chong) -- animals with shells or carapaces (turtles, tortoises, mussels, crabs, and the like). In the pre-Qin classification of five kinds of creatures: scaled (fish) correspond to spring, feathered (birds) to summer, naked (humans) to the center, furred (beasts) to autumn, and shelled to winter. Why do shelled creatures correspond to winter$30 Because their hard shells are inward-turning and deeply concealing, perfectly matching winter's qualities of "storing" and "closing." Shelled creatures hide their soft bodies within hard carapaces, just as winter conceals vital force deep beneath the earth -- a cosmic symbol of "storing."
"Its note is yu" -- the musical note of midwinter is "yu." Among the five notes (gong, shang, jue, zhi, yu), yu is the most deep and distant, its tonal quality resonant with water's depth and winter's hiddenness. The ancients held that each season has its particular "sound" -- the vibrational frequency of heaven and earth's qi in winter resonates with the yu note. The depth of the yu note matches the profundity of the Winter Solstice.
"Its number is six" -- the symbolic number of midwinter is six. In the pre-Qin numerological system: one and six belong to Water, two and seven to Fire, three and eight to Wood, four and nine to Metal, five and ten to Earth. "Six" belongs to Water, hence it is paired with winter. Specifically, "Heaven with the number one generates Water; Earth with the number six completes it" -- one is Water's "generating number," six its "completing number." At midwinter when Water's virtue reaches its extreme, its completing number "six" is taken. This correspondence between numbers and the Five Phases has extremely ancient origins, related to the tradition of the He Map and Luo Writing. Notably, "the number six" and the "seven days of return" (qiri laifu) of the Fu hexagram, which corresponds to the Winter Solstice, form a subtle resonance -- a point that will be discussed further below.
"Its flavor is salty" -- the taste of midwinter is salty. The pairing of the five flavors (sour, bitter, sweet, pungent, salty) with the Five Phases is: sour belongs to Wood (spring), bitter to Fire (summer), sweet to Earth (center), pungent to Metal (autumn), salty to Water (winter). Why does salty belong to Water$31 Because seawater is salty; the taste of water is salt. In the ancients' sensory system, taste was not merely a sensation of the tongue but a manifestation of heaven and earth's qi -- salty flavor is the expression of Water's virtue in the dimension of taste.
"Its odor is that of decay" -- the scent of midwinter is "decay" (xiu, the smell of rot). Among the five odors (rank, scorched, fragrant, fishy, decayed), decayed corresponds to Water and winter. Why the odor of decay$32 Because in winter, all things wither and return to stillness; grasses and trees rot and return to the earth -- this is the season of "decay." But "decay" is not purely death -- within decay, next year's vital force is nurtured, as rotting vegetation becomes the nourishment for new growth. This subtly connects with the Winter Solstice theme of "nurturing new life within the darkest hour."
"Its sacrifice is to the paths" -- the object of midwinter sacrifice is the spirit of paths (xing shen, the god of roads). Among the five domestic sacrifices (door, hearth, inner court, gate, paths), "paths" is paired with winter. Why sacrifice to the road spirit in winter$33 One understanding is that winter is governed by Water, and water flows along ditches and paths; another relates to year-end travel and year-end comings and goings. The spirit of paths governs safe passage; sacrificing to it at the year's end around the Winter Solstice expresses prayers for open roads and peace in the coming year.
"The offering begins with the kidneys" -- the organ first presented in sacrifice is the kidney. In the pairing of the five viscera with the Five Phases, the kidneys belong to Water and correspond to winter. The kidneys are the Water viscera, governing the storage of vital essence (jing), entirely consistent with winter's theme of "storing." In the understanding of Chinese medicine, the kidneys store prenatal essence, the very root of life -- just as winter harbors the root of next year's vital force. Offering the kidneys in sacrifice expresses the resonance between the body's "storing" and heaven and earth's "storing."
III. Why Did the Monthly Ordinances Construct Such a Precise Correspondence System$34
Reviewing the above analysis, we cannot help but ask: why did the Monthly Ordinances devote such extensive attention to constructing this precise system of cosmic correspondences$35 Was it not enough to know that "winter has come and it will be cold"$36
The answer is: for the ancients, merely knowing "winter has come" was far from sufficient. What they needed to know was: behind winter, in what manner is the entire cosmos operating$37 The constellations in the sky, the shelled creatures on earth, the kidneys in the human body, the salty flavor of food, the yu note in sound -- how are all these pervaded and linked by one and the same force of "Water's virtue"$38
This drive toward "threading all upon a single thread" is one of the most distinctive features of pre-Qin thought. The Master (Confucius) said: "My Way is threaded upon a single thread" (Lunyu, "Li Ren"). This "single thread" is not merely an ethical principle but a cosmological conviction -- though the myriad things of heaven and earth differ in a thousand ways, behind them all runs a single unifying law. The cosmic correspondence system constructed in the Monthly Ordinances is the concrete expression of this conviction.
Furthermore, this correspondence system was not merely epistemological but practical. It told rulers and the people: at the Winter Solstice, this season of extreme yin, what should be done and what should not. Only by keeping human affairs in step with the Way of Heaven could peace, good weather, and good harvests be ensured.
IV. The Son of Heaven's Conduct and Ordinances in Midwinter
The Monthly Ordinances specify in detail the Son of Heaven's conduct during midwinter: "The Son of Heaven dwells in the great temple of the Dark Hall, rides the dark chariot, drives iron-black horses, bears the dark banner, wears black robes, serves dark jade, eats millet and pork, and uses vessels that are broad and deep."
Why must the Son of Heaven in winter wear black, ride a black chariot, and drive black horses$39 Because winter belongs to Water, and Water's color is black (xuan). The Son of Heaven, as intermediary between heaven and earth, must harmonize all his conduct with the prevailing cosmic principle. Wearing black is not an aesthetic preference but a resonance with heaven and earth's "Water virtue." "Vessels broad and deep" -- broad to contain, deep to conceal -- perfectly accord with winter's quality of "storing."
Most noteworthy is the Monthly Ordinances' special record of the discipline of self-cultivation around the Winter Solstice: "In this month, the day reaches its shortest; yin and yang contend; all living things are unsettled. The exemplary person fasts and purifies himself; in his dwelling he must keep himself concealed; his body seeks tranquility; he distances himself from sensory indulgences, abstains from cravings, calms his body and nature, keeps his affairs quiet, and waits for yin and yang to settle."
"The day reaches its shortest" -- this is the Winter Solstice. "Yin and yang contend" -- these three words are of the utmost importance: at the moment of the Winter Solstice, yin has reached its peak while yang begins to stir, and the two forces are locked in intense contention. "All living things are unsettled" -- everything living is in a state of turbulence. Faced with this critical moment of yin-yang contention, how should the exemplary person respond$40 By fasting, by keeping himself deeply concealed, by seeking physical tranquility, by distancing himself from sensory stimuli, by abstaining from all cravings, by calming body and mind, by keeping affairs quiet, and by waiting in silence for yin and yang to settle.
This passage is of extreme importance, for it reveals the fundamental principle of Winter Solstice cultivation: at this most delicate moment when the first yang has just been born and yin and yang contend, the most important thing is "stillness." Why$41 Because the newborn yang is like a seed that has barely begun to stir -- extremely feeble, extremely tender, needing to grow silently in absolute tranquility. Any external disturbance -- sensory stimulation, cravings, agitation -- might damage this thread of nascent yang. This point will be further elaborated in the chapter on self-cultivation below.
V. The Monthly Ordinances' Warning: Consequences of Untimely Decrees
The Monthly Ordinances also sternly warn of the consequences of inappropriate governance during midwinter: "If in midwinter one enacts the ordinances of summer, the state will suffer drought, mist and fog will darken, and thunder will sound. If one enacts autumn's ordinances, untimely rain will fall, gourds will fail to mature, and the state will face warfare. If one enacts spring's ordinances, locusts will ravage, springs and streams will dry up, and the people will suffer from skin ailments and plague."
The logic behind these warnings rests on a core conviction: each season has its specific "qi," and governmental decrees likewise have their specific "qi." Winter's decrees should be those of "storing," "closing," and "stillness"; enacting decrees appropriate to "generation" (spring), "growth" (summer), or "harvest" (autumn) during winter would create a clash of qi and provoke disaster. Especially telling is "thunder will sound" -- thunder should properly begin with the Awakening of Insects in spring; thunder in winter signifies a premature, excessive outpouring of yang, a severe disruption of the latent nascent yang, and thus a portent of great misfortune.
From a modern perspective, these causal connections lack scientific basis. But from another angle, the Monthly Ordinances' warnings contain profound political wisdom: governance should have its rhythm, and especially at year's end when all things return to storage, one should rest and nurture, maintain quiet and preservation, and avoid rash action or disturbance of the people. This wisdom of "governing in accord with the seasons" retains its value to this day.
VI. Why "Midwinter"$42 The Pivot Among Winter's Three Months
Finally, we must ask a question easily overlooked yet crucial: why does the Winter Solstice fall precisely in "midwinter" (the second, middle month of winter), rather than in early winter (mengdong) or late winter (jidong)$43 What deeper meaning does this placement hold$44
The ancients divided each season into three months: meng (early), zhong (mid), and ji (late). Winter's three months are early winter (tenth month: Start of Winter and Minor Snow), midwinter (eleventh month: Major Snow and Winter Solstice), and late winter (twelfth month: Minor Cold and Major Cold). The Winter Solstice falls precisely in midwinter -- the exact center of winter.
Why must the Winter Solstice stand at winter's center$45 This perfectly accords with the essential meaning of "zhi" as "extreme." The Winter Solstice is the extreme of yin, the core pivot of the entire winter season, and it rightly occupies the central position -- just as the Summer Solstice occupies the center of summer (midsummer). This arrangement of "the two solstices at center" embodies a profound symmetry and balance. Before the Winter Solstice, early winter sees the "beginning of storing" (Start of Winter, when all things begin to withdraw); after the Winter Solstice, late winter sees the "extreme of storing" (Major Cold, the ultimate depth of storage); the Winter Solstice itself is the pivot of this process of withdrawal -- before it, yin grows and vital force retreats; after it, though the weather may grow even colder (the Minor and Major Cold of late winter), the Way of Heaven has already seen yang's return and the beginning of its ascent.
At a deeper level, the Winter Solstice's position at the center of midwinter reveals the offset between "the astronomical extreme" and "the climatic extreme." Astronomically, the Winter Solstice (center of midwinter) is the point of maximum yin; climatically, the coldest period falls after the Winter Solstice in late winter (Minor and Major Cold, corresponding to the "third nine" and "fourth nine" of the Counting Nines). This offset is given institutional expression in the Monthly Ordinances' meng-zhong-ji structure: the Winter Solstice (astronomical extreme of yin) falls in midwinter, while the climatic extreme of cold falls in late winter. This demonstrates that the ancients' basis for establishing the Winter Solstice was astronomical (the longest shadow, the extreme of yin), not simply climatic warmth or cold. They seized upon the objective extreme of the Way of Heaven's operation (the longest shadow), not the subjective extreme of felt temperature. This once again reveals the objectivity, precision, and depth of the ancients' astronomical observation: the Winter Solstice stands at midwinter's center precisely because it is the extreme of the Way of Heaven, not the extreme of climate.
