Grain and Fire as Autumn: The Severance of Heaven and Earth and the Onset of Solemn Killing at Liqiu
This article offers an in-depth interpretation of Liqiu (Start of Autumn) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, and astronomical-phenological perspectives. By examining the etymological roots of 'qiu' (autumn) as grain-and-fire, the astronomical coordinate of 135° solar longitude, and the image of Hexagram Pi (Standstill) from the Yijing — 'Heaven and Earth do not interact' — it reveals Liqiu as the pivotal moment when all things shift from 'growth' to 'gathering,' illuminating the virtue of Metal, the onset of solemn killing, and the ancient roots of the autumnal grief tradition.

Chapter Three: "The Month of Early Autumn" in the Liji "Monthly Ordinances" — The Complete Portrait of Metal Virtue
I. The Nature of the Monthly Ordinances: An Action Program Between Heaven and Humanity
Among all pre-Qin texts, the most detailed and systematic description of Liqiu and its month of Early Autumn is found in the "Yueling" ("Monthly Ordinances") of the Liji (its content highly parallels the "Ji of Early Autumn" in the Lushi Chunqiu; scholars generally regard them as sharing a common source). The Monthly Ordinances are not mere calendrical records but a complete program of action between heaven and humanity — telling us, at each specific temporal node, how celestial phenomena stand, how earthly things stand, and how human affairs ought to stand. If the Monthly Ordinances for Lichun overflow with the joy of burgeoning growth, and those for Lixia brim with the generosity of flourishing, then the ordinances for Early Autumn are pervaded by the solemn atmosphere of rectification, convergence, and even solemn killing.
Following the celestial coordinates discussed above, the "Yueling" proceeds to describe the Five Phases attributes of the month of Early Autumn, constructing a complete cosmic portrait of Metal virtue:
"Its days are geng and xin; its sovereign is Shaohao; its spirit is Rushou; its creatures are the furred; its note is shang; its number is nine; its taste is acrid; its smell is rank; its sacrifice is at the gate; the offering begins with the liver."
This passage constructs an extraordinarily precise system of cosmic correspondences. Let us analyze each in depth.
II. The Portrait of Metal Virtue, Part One: Heavenly Stems, Sovereign, Spirit
"Its days are geng and xin" — The month of Early Autumn corresponds to the Heavenly Stems geng (庚) and xin (辛). Among the ten Heavenly Stems, geng and xin belong to Metal. The correspondences are: jia and yi belong to Wood (spring), bing and ding to Fire (summer), wu and ji to Earth (center/late summer), geng and xin to Metal (autumn), ren and gui to Water (winter). The ancient meaning of geng connotes "change" and "renewal"; the Shuowen says "Geng occupies the western position, symbolizing that in autumn, all things are geng-geng — bearing solid fruit." The character xin carries associations of pungency and hardship. The two characters themselves already contain autumn's connotations of transformation, harvest, and solemn killing.
"Its sovereign is Shaohao" — The presiding sovereign deity of Early Autumn is Shaohao (also written Shao Hao), the Golden Heaven Sovereign. This corresponds to the Five Phases system of five emperors: the emperor of spring is Taihao (Wood virtue), of summer the Flame Emperor (Fire virtue), of the center the Yellow Emperor (Earth virtue), of autumn Shaohao (Metal virtue), and of winter Zhuanxu (Water virtue). Shaohao, titled Lord of Golden Heaven (Jintianshi), is the celestial emperor of the west and of Metal virtue in high antiquity. Why does Shaohao preside over autumn$13 The Zuozhuan records the famous account of Tan Zi discussing how the Shaohao clan named their officials after birds — at Shaohao's establishment, "a phoenix arrived, and so he used birds as his system, establishing bird-masters with bird-names." Birds are feathered creatures that can soar high, and autumn is precisely the season when wild geese fly south and birds migrate. Shaohao's use of birds for governance subtly resonates with autumn's atmosphere of transformation and solemn order.
"Its spirit is Rushou" — The assisting spirit of Early Autumn is Rushou (蓐收). Rushou is the Metal God, the Autumn God, and the Spirit of the West in high-antiquity mythology — the minister of Shaohao. He is the most important and most awe-inspiring figure in Liqiu's mythological pantheon. The Guoyu ("Discourses of the States," "Jin yu 2") records a spine-chilling story: Duke of Guo dreamed that in his ancestral temple stood a spirit, "with a human face, white hair, tiger's claws, holding a battle-axe, standing at the western eave." Terrified, the Duke fled, but the spirit stopped him and delivered a command from the High Sovereign. Upon waking, the Duke summoned the historian Shi Xiao to interpret the dream, who declared: "As your lordship describes it, that is Rushou — Heaven's Spirit of Punishment." This fearsome deity with white hair, tiger claws, and a great battle-axe was none other than Rushou — "Heaven's Spirit of Punishment." The Shanhaijing (Classic of Mountains and Seas), "Western Mountains Classic," also records: "Mount You — the spirit Rushou dwells there... This mountain looks west toward where the sun sets." We shall discuss this Metal God in a dedicated chapter below; for now, let us remember: the spirit of autumn is one who wields a sharp axe and presides over punitive killing. This image sets the keynote for the entire season: solemn rectification, decisive judgment, life and death.
III. The Portrait of Metal Virtue, Part Two: Creatures, Note, Number
"Its creatures are the furred" — The representative animal category of Early Autumn is "furred creatures" — beasts (fur-bearing animals such as tigers and leopards). In the pre-Qin fivefold division of animals, all creatures were classified as: scaled (fish and dragons, corresponding to spring Wood), feathered (birds, corresponding to summer Fire), naked (humans, corresponding to central Earth), furred (beasts, corresponding to autumn Metal), and shelled (crustaceans, corresponding to winter Water). Beasts correspond to autumn partly because autumn is when animals have their fullest pelts and fattest bodies, ideal for hunting; at a deeper level, fierce beasts such as tigers and leopards inherently embody qualities of solemn killing, ferocity, and predation — perfectly matching autumn Metal's virtue of solemn killing. Rushou's "tiger claws," noted above, resonate with Early Autumn's association with furred creatures — the Metal God displays tiger claws precisely because the tiger is the representative furred creature of autumn, a symbol of solemn ferocity.
"Its note is shang" — The musical note of Early Autumn is shang (商). Among the five tones (gong, shang, jue, zhi, yu), shang is clear, vigorous, and austere, carrying a quality of desolation, melancholy, and resolve. Later tradition used "shang sound" as a metonym for the sound of autumn and of sorrow, originating precisely from this. Ouyang Xiu's declaration in his "Rhapsody on the Sounds of Autumn" (Qiu sheng fu) that "shang sound is the note of the west" traces its root to the Monthly Ordinances' "its note is shang." In the ancients' musical cosmology, each season's qi possesses a specific vibrational frequency, and the clear, austere quality of shang resonates with autumn Metal's character of solemn rectification, convergence, and melancholy.
"Its number is nine" — The symbolic number of Early Autumn is nine. In pre-Qin numerical arts, 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. Nine (paired with four) belongs to Metal, hence its assignment to autumn. Notably, nine is the ultimate yang number (the largest among 1, 3, 5, 7, 9). Why should this supremely yang number be assigned to a season of rising yin$14 Here lies a profound dialectic — nine is yang's extreme, and yang at its extreme is precisely the beginning of yin's birth. Autumn, though yin grows within it, follows directly upon the yang extreme of the summer solstice; it is the starting point of descent from yang's pinnacle. Assigning the ultimate yang number nine to autumn hints precisely at this: autumn's convergence begins from yang qi's supreme fullness. This assignment places autumn at the pivot of the yin-yang transformation.
IV. The Portrait of Metal Virtue, Part Three: Taste, Smell, Sacrifice, Organ
"Its taste is acrid" — The taste of Early Autumn is acrid (pungent). Among the five tastes (sour, bitter, sweet, acrid, salty) and their Five Phases correspondences: sour belongs to Wood (spring), bitter to Fire (summer), sweet to Earth (late summer/center), acrid to Metal (autumn), salty to Water (winter). Acrid taste is dispersing, sharp, and penetrating — qualities that match Metal's keen severity.
"Its smell is rank" — The odor of Early Autumn is rankness. Among the five odors, rankness is the smell of Metal qi — the scent of metal, blood, and raw flesh. Autumn's solemn killing brings the commencement of hunting and butchering; the smell of blood accords with autumn's themes of solemn killing and punishment.
"Its sacrifice is at the gate" — The sacrificial object of Early Autumn is the gate deity. The gate (men 门) is a threshold between inside and outside, a boundary. Autumn is the season of convergence, when all things shift from the outside inward — just as one enters through a gate to return inside. The gate symbolizes "gathering in," perfectly matching autumn's virtues of convergence, enclosure, and boundary-keeping.
"The offering begins with the liver" — The organ first offered in sacrifice is the liver. Notably, this Monthly Ordinances assignment of the liver to autumn differs from the later medical tradition, which assigns the lung to Metal and autumn. This divergence reflects the fact that pre-Qin Five Phases–organ correspondences had not yet been fully unified across different periods and schools.
V. The Portrait of Metal Virtue, Part Four: The Son of Heaven's Conduct — Venerating White and Solemn Rectification
The Monthly Ordinances prescribe in great detail the Son of Heaven's residence, carriages, clothing, and diet during the month of Early Autumn, with the themes of Metal virtue, the west, and the color white pervading throughout:
"The Son of Heaven resides in the left chamber of Zongzhang Hall, rides in the war chariot, drives white horses with black manes, flies white banners, wears white robes, girds white jade, eats hemp seeds and dog meat, and uses vessels with sharp edges and deep form."
Why must the Son of Heaven venerate white in autumn$15 Because autumn belongs to Metal, and Metal's color is white. As the intermediary between heaven and earth, the Son of Heaven's every act must accord with the prevailing cosmic principle. Wearing white, driving white horses, and girding white jade are not aesthetic preferences but cosmic resonance with the Metal virtue of heaven and earth.
Especially notable is "rides in the war chariot" (cheng ronglù). In spring, the Son of Heaven rides a carriage with phoenix bells; in summer, a vermilion carriage; at Liqiu, he switches to a war chariot. This change is deeply significant — it signals the profound connection between autumn and military affairs, punishment, and warfare. Autumn belongs to Metal; Metal governs solemn killing and weapons of war. The Son of Heaven mounting a war chariot in autumn is an act of accord with autumn Metal's martial qi.
VI. The Portrait of Metal Virtue, Part Five: The Ceremony of Welcoming Autumn and the Governance of Solemn Killing
The Monthly Ordinances prescribe the formal ritual for the day of Liqiu and the administrative orders for the month, centered on "welcoming autumn" and "initiating solemnity":
"This month marks Liqiu. Three days before Liqiu, the Grand Historian informs the Son of Heaven: 'On such-and-such a day is Liqiu; the prevailing virtue is Metal.' The Son of Heaven then undergoes purification. On the day of Liqiu, the Son of Heaven personally leads the Three Dukes, Nine Ministers, feudal lords, and grandees to welcome autumn at the western suburbs. Upon returning, he rewards military commanders and warriors at court. The Son of Heaven then commands his generals to select soldiers, sharpen weapons, train outstanding men, appoint those of merit, so as to punish the unjust, chastise the violent and insolent, clarify what is favored and what reviled, and bring distant lands to submission."
Why must autumn be welcomed at the western suburbs$16 Because the west belongs to Metal, and autumn comes from the west. Welcoming spring at the eastern suburbs, summer at the southern suburbs, autumn at the western suburbs, and winter at the northern suburbs — the directional assignments strictly follow the Five Phases system.
And the commands issued upon returning from the ceremony reveal autumn Metal's nature of solemn killing with vivid clarity: rewarding "military commanders and warriors," commanding generals to "select soldiers and sharpen weapons," punishing "the unjust," and chastising "the violent and insolent." This is the origin of the famous principle of "autumn executions" (qiujue) — punishments, warfare, and other acts of a "solemn killing" nature should be conducted in autumn, in accord with autumn Metal's qi of solemn killing.
VII. The Monthly Ordinances' Warning: Consequences of Untimely Commands
The Monthly Ordinances, after describing what should be done in the month of Early Autumn, sternly warn of the consequences of improper action:
"If in the month of Early Autumn one carries out winter commands, yin qi will become excessively dominant, shelled insects will ruin the grain, and warfare will come. If one carries out spring commands, the state will suffer drought, yang qi will return, and the five grains will bear no fruit. If one carries out summer commands, the state will suffer many fires, heat and cold will be unregulated, and the people will suffer much malaria."
These warnings rest on a core conviction: each season has its specific qi, and administrative orders also have their characteristic qi. If in autumn — when orders should be "gathering," "solemn," and "judging" — one issues instead the "excessive storage" of winter, the "excessive growth" of spring, or the "excessive expansion" of summer, the resulting clash of qi mechanisms will bring catastrophes of climate, agriculture, and even warfare. Particularly noteworthy: "If one carries out spring commands... yang qi will return, and the five grains will bear no fruit" — if one issues growth-promoting spring orders during the season that should be convergent, yang qi will resurge, and grain will fail to condense its essence into seed. This confirms, by negation, the supreme importance of autumn's "gathering."
From a modern standpoint, such causal relations lack scientific basis. Yet from another angle, these warnings contain a profound political wisdom: governance must have its rhythm. When it is time to gather, gather; when to release, release. Though the Monthly Ordinances frame this wisdom within the structure of Heaven-Humanity resonance, its core insight — that governance must accord with the rhythm of objective circumstances — retains its value today.
