From End to Beginning: The Way of Culmination and Return in the Great Cold Solar Term
This article offers a deep reading of Great Cold (Dahan), the final of the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical and phenological traditions. It reveals the dialectic of extreme cold and returning spring, the cyclic principle that every ending harbors a new beginning, and illuminates the late-winter rites of the Grand Nuo exorcism and the clay ox ceremony—inviting the reader into the ancients' cosmic wisdom of 'tracing origins by returning to endings' and the eternal circle of ceaseless renewal.

Chapter Three: The Final Month of Winter in the "Monthly Ordinances" of the Record of Rites: A Cosmic Portrait of Year's End
I. The Final Month of Winter: The Gathering of a Year's Governance
Among all pre-Qin texts, the most detailed and systematic description of Great Cold and its encompassing final month of winter belongs to the "Monthly Ordinances" (Yueling) of the Record of Rites (Liji) (its content is highly consistent with the "Records of the Final Month of Winter" in the Lushi Chunqiu; scholars generally hold that both derive from a common source). The Monthly Ordinances is not a simple calendrical record but a complete guide for action linking heaven and humanity--telling us, at specific temporal junctures, what the celestial signs are, what the earthly phenomena are, and what human affairs should be. The Monthly Ordinances for the final month of winter, as the last of all twelve months, possesses the special character of "gathering and concluding the whole."
The Record of Rites, "Monthly Ordinances," sketches a complete cosmic portrait for the final month of winter. Its opening reads:
"In the final month of winter, the sun is in the lunar lodge Nv (Maiden); at dusk, the lodge Lou (Bond) culminates; at dawn, the lodge Di (Base) culminates."
These three lines indicate the positions of the sun, the constellation at the southern meridian at dusk, and the constellation at the southern meridian at dawn. The sun is in the lodge Nv--it has traveled to the position of the Maiden; at dusk, the Bond lodge stands at the center of the southern sky; at dawn, the Base lodge stands at the center of the southern sky. These stellar positions were the astronomical basis by which the ancients determined the season. As the year nears its end, the sun reaches the Maiden, arriving at its appointed station in the starry heavens for this revolution of the cycle.
II. Water Virtue at Its Peak: The Five Phases Correspondences of the Final Month of Winter
Next, the Monthly Ordinances describes the Five Phases attributes of the final month of winter. This set of correspondences is shared by the entire winter season (early, mid, and late winter), but in the final month--at the year's very end where Great Cold resides--it reaches its most pure and extreme state:
"Its days are ren and gui; its emperor is Zhuanxu; its spirit is Xuanming; its creature is the armored; its tone is yu; its number is six; its flavor is salty; its smell is putrid; its sacrifice is at the road-crossing; in sacrifice, the kidney is offered first."
This passage constructs an exceedingly precise system of cosmic correspondences. Let us analyze each one, appreciating its deeper significance in the specific context of "year's end."
"Its days are ren and gui"--The final month of winter corresponds to the Heavenly Stems ren and gui. Among the ten Stems, ren and gui belong to Water. This is because the ten Stems' correlation with the Five Phases runs: jia-yi = Wood (spring), bing-ding = Fire (summer), wu-ji = Earth (center), geng-xin = Metal (autumn), ren-gui = Water (winter). Winter belongs to Water, hence the pairing with ren and gui. Furthermore, ren and gui occupy the last two positions among the ten Stems--jia, yi, bing, ding, wu, ji, geng, xin, ren, gui: at ren-gui the sequence is exhausted. Pairing the final Stems (ren-gui) with the final month (late winter) was no coincidence, but the ancients' deliberate arrangement of "following like categories," making the temporal sequence and the Stems sequence correspond end to end. The year has traveled to the Water of ren-gui, just as the Stems have reached their terminus; the next step must return to the Wood of jia-yi, restarting spring's cycle.
"Its emperor is Zhuanxu"--The presiding emperor of the final month of winter is Zhuanxu. Zhuanxu is the legendary Emperor of the North, the Emperor of Water Virtue. In the Five-Phases-Five-Emperors system: the emperor of spring is Taihao (Wood Virtue), of summer Yandi (Fire Virtue), of the center Huangdi (Earth Virtue), of autumn Shaohao (Metal Virtue), and of winter Zhuanxu (Water Virtue). Why does Zhuanxu, this emperor of Water Virtue dwelling in the north, preside over winter--especially the year-end's final month$27 The Huainanzi, "Treatise on Celestial Patterns," states: "The north is Water; its emperor is Zhuanxu; his assistant is Xuanming; holding the balance, he governs winter." Zhuanxu, with Water Virtue in the north, governing the winter ordinances, is the embodiment of the powers of depth, stillness, and concealed storage. At the year's end during Great Cold, when all things are stored beneath the earth and life lies dormant in the deepest yin, Zhuanxu's Water Virtue reaches its fullest expression.
"Its spirit is Xuanming"--The assistant spirit of the final month of winter is Xuanming, the ancient mythological god of water and winter. "Xuan" means black, dark, abyssal; "ming" means obscure, fathomless. Combined, "Xuanming" depicts a state of ultimate depth and darkness, unfathomable and impenetrable--the very image of deep winter, of the year-end's most extreme yin-qi. The Zuozhuan, in the twenty-ninth year of Duke Zhao, records: "The officer of Water is called Xuanming." In remote antiquity there was an officer of Water, charged with Water Virtue and winter affairs, whose spirit was Xuanming. Xuanming governs winter's sealed concealment and silence, allowing all things to sleep, rest, and store their reserves in darkness and cold.
Why have both an "emperor" and a "spirit"$28 This reflects a core tenet of pre-Qin political philosophy: governance requires hierarchical division of labor. The emperor is the supreme sovereign, responsible for setting the grand direction; the spirit is the specific executor, responsible for carrying out the emperor's will. Zhuanxu as Emperor of Water Virtue represents winter's macroscopic order; Xuanming as the Water Spirit handles the concrete "work"--allowing cold to pervade, waters to freeze, and all things in the dark of concealment to await spring's return.
"Its creature is the armored"--The representative category of animal for the final month of winter is "armored creatures" (jie chong)--those with shells (turtles, soft-shelled turtles, mussels, crabs, and the like). In the pre-Qin animal classification system, creatures were divided into five categories: scaled (fish, spring), feathered (birds, summer), bare (humans, center), furred (beasts, autumn), and armored (shelled, winter). Why do armored creatures correspond to winter$29 Because the shell is a form of "enclosing," "sealing," "sheltering"--armored creatures protect their soft bodies within hard shells, just as winter causes heaven and earth to seal up the vitality of all things within severe cold. The "storage" of armored creatures is winter's "storage" incarnated in the animal world. At the year-end Great Cold, all things are like armored creatures, deeply hiding their bodies, firmly guarding their interiors--the utmost of the virtue of "storage."
"Its tone is yu"--The final month of winter corresponds to the yu tone in the five tones (gong, shang, jue, zhi, yu). Yu is the most low-pitched and distant of the five, its sonic quality corresponding to water's depth and winter's silence. The ancients believed each season had its characteristic "sound"--the vibration frequency of heaven and earth's vital breath in winter resonates with the yu tone. Yu is low, receding, sinking inward--just as winter's vital breath moves downward, inward, deeper into concealment.
"Its number is six"--The symbolic number of the final month of winter is six. In the pre-Qin numerical arts, one-six pertain to Water, two-seven to Fire, three-eight to Wood, four-nine to Metal, five-ten to Earth. Six belongs to Water, hence paired with winter. This system of number-Phase correspondences originates from great antiquity, possibly related to the River Diagram and Luo Writing traditions. "Heaven's one generates Water; Earth's six completes it"--one is Water's generating number, six its completing number. Assigning six (Water's completing number) to the final month of winter signifies that winter's Water Virtue has by year's end been "completed"--fulfilled, perfected, brought to its extreme.
"Its flavor is salty"--The flavor of the final month of winter is salty. The five flavors (sour, bitter, sweet, pungent, salty) correspond to the Five Phases: sour to Wood (spring), bitter to Fire (summer), sweet to Earth (center), pungent to Metal (autumn), salty to Water (winter). Why does saltiness belong to Water$30 The most direct association is the saltiness of seawater--the greatest of all waters is the sea, and seawater is salt. In the ancients' sensory system, flavor was not merely a sensation of the tongue but a manifestation of heaven and earth's vital breath. The sinking, inward-drawing quality of salty flavor corresponds to Water Virtue's downward movement and concealed storage.
"Its smell is putrid"--The smell of the final month of winter is "putrid" (xiu). "Putrid" denotes the scent of decay and antiquation. Among the five scents (rank, scorched, fragrant, raw, putrid), putrid corresponds to Water and winter. Why "putrid"$31 Because winter is the season when all things wither, decay, and return to the earth--plants fall and decompose into soil; the "old" forms of all things disintegrate and rot, returning themselves to heaven and earth. Yet within "putrid" is secretly hidden the seed of new life--decaying plants become fertilizer for the coming spring, the withering of the old year is the precondition for the sprouting of the new. At the year-end Great Cold, the scent of decay is strongest, and at decay's furthest reach lies the "birth" of spring.
"Its sacrifice is at the road-crossing"--In the final month of winter, the sacrifice is offered to the "Road" god (xing). Among the five household sacrifices (door, stove, gate, road, central courtyard), "road" is paired with winter. Why sacrifice to the road god at winter's end$32 One interpretation is: winter is the season of travel and homecoming--at year's end, wanderers return to their native places and travelers head home, all relying on roads; sacrificing to the Road god to pray for safe travel and smooth homecoming accords with year-end reunion and the farewell to the old and welcome of the new. A deeper reading holds that "road" (xing) signifies movement, passage, unceasing circulation--at the year's end, when one journey is about to conclude and another about to begin, sacrificing to the Road god is a gesture of reverence for the cyclical Way, "Heaven's movement is unceasing" and "circulating without peril."
"In sacrifice, the kidney is offered first"--The organ first presented at the sacrifice is the kidney. In the correspondences of the five organs and the Five Phases, the kidney pairs with Water and with winter. In traditional medical theory, the kidney governs "storing essence" and "sealing and storage"--it is the fundamental organ in the human body for concealing, collecting, and accumulating vital essence. Pairing the kidney with winter reflects winter as heaven and earth's season of "storing essence," while the human kidney is the corresponding organ of this "storage" virtue in the body. At the year-end Great Cold, nourishing the kidneys and storing essence is the fundamental principle of health cultivation in accord with the season's timing, which we shall discuss in detail in the later chapter on self-cultivation.
III. Why the Final Month's Correspondences Signify "Extreme" and "Reversal"
Reviewing the analysis above, we discover that the entire set of Five Phases correspondences for the final month of winter--Water, north, black, Zhuanxu, Xuanming, armored creatures, yu tone, the number six, salty flavor, putrid scent, kidney--every one of them points toward "depth," "sealed concealment," "stillness," "utmost yin." This is the picture of winter's Water Virtue at its absolute pinnacle.
But the pinnacle is precisely where reversal begins. This is the most profound dialectic of the pre-Qin cosmological view. When we see that the final month of winter's Water Virtue, yin-qi, and sealed concealment have all reached the state of "extreme," we should immediately recognize: the tipping point of "when things reach their extreme they must reverse" has arrived. The Lushi Chunqiu, "Records of the Final Month of Winter," after describing the various signs of sealed concealment in this month, is precisely laying the groundwork for the upcoming first month of spring (Start of Spring) and its "growth and emergence." The year's Monthly Ordinances conclude with the final month's utmost yin, and this very conclusion is the gathering of momentum for the next year's first month's sprouting.
The "extreme character" of the final month's Five Phases correspondences should therefore not be understood as a "dead end," but as a "fully drawn bow"--the bow drawn to its fullest is the moment the arrow is about to fly; yin accumulated to its utmost is the moment yang is about to revive. The entire cosmic portrait of Great Cold--on its surface "storage at its extreme," "yin at its extreme," "cold at its extreme"--within itself pulses with the forces of "about to be born," "about to become yang," "about to become spring."
IV. The Son of Heaven's Conduct in the Final Month of Winter: Black Vestments and the Northern Direction
The Monthly Ordinances prescribes detailed regulations for the Son of Heaven's conduct in the final month of winter, continuing the keynote of the entire winter season:
"The Son of Heaven dwells in the right chamber of the Dark Hall; he rides the dark chariot drawn by dark-iron horses; he displays dark banners; he wears black garments; he adorns himself with dark jade; he eats millet and pork; his vessels are vast and sealed."
The Son of Heaven in the final month of winter should reside in the western side-chamber ("right chamber") of the Dark Hall (the north-facing portion of the Bright Hall); ride a black chariot ("dark chariot"); be drawn by black horses ("dark-iron steeds," iron-blue tending to black); display black banners ("dark banners"); wear black garments ("black clothing"); wear black jade ornaments ("dark jade"); eat millet and pork ("millet and swine"); and use vessels that are "vast and sealed" (hong yi yan)--large and deeply closed.
Why must the Son of Heaven in the final month of winter wear black, ride black chariots, and drive black horses$33 This was no aesthetic preference, but a cosmological requirement--winter belongs to Water, and Water's color is black (xuan). The Son of Heaven, as the mediator between heaven and earth, must keep all his conduct in harmony with the cosmic law prevailing at the given time. He wears black not for solemnity's sake, but to resonate with heaven and earth's "Water Virtue," thereby ensuring harmony between heaven and humanity.
"Eating millet and pork" also repays closer examination. Millet is a cold-resistant grain, and pork (swine) in the Five Phases correlations relates to Water and the north. What the Son of Heaven eats is not a matter of personal dietary preference but a cosmological act--by consuming food corresponding to the current season's Five Phases attribute, the Son of Heaven takes heaven and earth's vital breath into his own body, becoming the vessel of that breath in the human world.
"His vessels are vast and sealed" relates to Water's and winter's characteristics--"vast" (hong) means capacious and deep, "sealed" (yan) means covered and deeply closed. Vessels that are vast and deeply sealed accord precisely with winter's traits of concealment, storage, and depth. The form of vessels was not the arbitrary design of craftsmen, but the expression of Heaven's Way in the material realm.
V. Governance for the Final Month of Winter: Sealed Storage and Preparations for Year's End
The Monthly Ordinances prescribes various acts of governance for the final month of winter, centered on "sealed storage" and "preparations for year's end." The two most important and distinctive items will be treated in dedicated later chapters--one being "Command the officials to perform the Grand Nuo, sacrifice at the four gates, send forth the clay oxen, to see off the cold" (the Grand Nuo exorcism and clay ox ceremony to bid farewell to cold and welcome spring), and the other being various year-end preparations (assessment of taxes, planning for the coming year's agriculture). Here we first consider the summary statement:
"In this month, the sun reaches the limit of its stations, the moon reaches the limit of its circuits, the stars return to their places in heaven, the count is nearly done, and the year is about to begin anew."
These five lines are among the most moving and philosophically rich in the entire Monthly Ordinances, directly revealing the whole secret of the final month of winter and of Great Cold. "The sun reaches the limit of its stations"--the sun's journey along the ecliptic has come to the end of its annual cycle (the "stations" being the twelve zodiacal stations through which the sun travels). "The moon reaches the limit of its circuits"--the moon's journey too has come to its end. "The stars return to their places in heaven"--the stars have completed their revolution and returned to their original positions. "The count is nearly done"--the tallying of years, months, and days is about to conclude. "The year is about to begin anew"--a new year is about to start.
Savor the structure of this passage: the first four lines--"sun at its limit," "moon at its limit," "stars returned," "count finished"--fully express the year's "ending": sun, moon, stars, and count have all reached their terminus. Yet the final line, "the year is about to begin anew," suddenly pivots, flipping from "ending" directly to "beginning"! After "limit" and "finished" comes immediately "begin anew"--restart. This passage in the Monthly Ordinances is the most condensed, most poetic expression of the cosmic law "when things end, they begin again." The year's vital breath reaches its absolute terminus at Great Cold (sun at its limit, moon at its limit, stars returned, count finished), and precisely at this absolute terminus, the new year "begins anew."
Why does the Monthly Ordinances specifically highlight "the year is about to begin anew" at the end of the final month$34 Because this is the ancients' deepest insight into year's end: ending is never the abyss of nothingness, but the threshold of renewal. Sun, moon, and stars complete their circuit not to stop, but to set out again. Great Cold, as the point at which "sun exhausted, moon exhausted, stars returned, count completed," is simultaneously the starting point of "the year about to begin anew."
VI. The Warnings of the Monthly Ordinances: Consequences of Untimely Governance
After describing the proper conduct for the final month of winter, the Monthly Ordinances sternly warns of the consequences of improper conduct:
"If in the final month of winter one enacts autumn's ordinances, white dew falls early, armored creatures become portents, and people of the four borders flee into the walled towns. If one enacts spring's ordinances, embryos and young suffer much harm, the state is beset with chronic illness, and this is called 'going against.' If one enacts summer's ordinances, floods ruin the state, seasonal snow fails to fall, and ice and frost dissolve."
Among these warnings, the one about "enacting spring's ordinances... called 'going against'" is particularly thought-provoking. Why is prematurely issuing spring's ordinances of growth and release during the final month of winter (when concealment is called for) sternly condemned as "going against" (ni)$35 This confirms from the opposite side the essential nature of Great Cold as "storage at its extreme." At year's end, the Way of Heaven lies in "storage," in "sealing," in nurturing life's reserves for the coming spring. To forcibly promote growth at this time (enacting spring's ordinances) is to pull up seedlings to hasten their growth, to leak vital energy that should remain deeply stored, to run counter to the Way of "storage." Hence it is called "going against," and its consequence is "embryos and young suffer much harm"--new life that should have been safely gestating in concealment is damaged by premature release of vital energy.
This warning contains an exceedingly deep wisdom: the "birth" of spring can only arrive naturally after Great Cold's "storage" has been fully nourished. If one grows impatient with "storage" and rushes toward "birth," life's vital energy is instead harmed. Great Cold's "storage" and Start of Spring's "birth" are two sides of one coin, mutually causal--without the fullness of Great Cold's storage, there can be no vigor in Start of Spring's birth. This is also why Great Cold must conclude the year with "the utmost in sealed storage": only when storage is deep enough and full enough can the coming spring's birth be vigorous and sound.
From a modern perspective, this causal relationship naturally lacks scientific basis. Yet the Monthly Ordinances' warnings contain a profound wisdom: all things have their proper season for action, and forcibly violating the temporal order inevitably brings harm. To attempt growth when one should be gathering and nourishing, to rush into expansion when one should be quietly accumulating--whether in agriculture, governance, or the cultivation of the body--is the path to disaster.
