The Frost's Descent and the Reversed Woman: An Inquiry into the Ritual, Heavenly Way, and Moderation of Pre-Qin Marriage Regulations
This article deeply interprets the twelve characters, 'The Frost's Descent and the Reversed Woman, Ice Thaws and Killing Ceases, One Coitus in Ten Days,' tracing their origins in Pre-Qin classics like the *Rites of Zhou* and the *Book of Rites*. It analyzes the underlying principles concerning temporal restrictions on marriage, Yin-Yang philosophy, agricultural governance considerations, and sexual moderation, aiming to reconstruct the core of Pre-Qin ritualistic thought.

Chapter 6: The Deeper Meaning of "Cessation Kills" — Pre-Qin Taboo Thought
Section 1: "Cessation Kills" and Seasonal Taboos
The "cessation kills" (shā zhǐ) in "ice thaws, cessation kills" (冰泮杀止) is not just the cessation of marriage but also embodies a series of seasonal taboos.
In the Pre-Qin concept of Monthly Ordinances, each season had matters to be carried out and matters to be forbidden. Carrying out the proper tasks aligns with the Heavenly Dao; forbidding the improper tasks also aligns with the Heavenly Dao.
The Book of Rites, "Monthly Ordinances," specifies prohibitions for every month. For example, in the first month of spring:
"Prohibit the felling of trees; do not overturn nests; do not kill young insects, nascent beings, or flying birds; do not take suckling animals or eggs." (Liji 礼记·月令)
In the second month of spring:
"Do not drain rivers and marshes; do not dredge ponds; do not burn mountains and forests."
In spring, all things grow, hence all acts of killing and destruction are forbidden. This is the "Taboo of Generation" (shēng jìn)—because spring is the season of generation, killing is forbidden.
Conversely, autumn and winter are seasons of contraction and killing.
The Monthly Ordinances for the third month of autumn states:
"The performance of execution begins."
For the third month of winter:
"Then hasten judicial punishments; do not allow the guilty to remain."
In autumn, the execution of penalties begins; in winter, it becomes stricter. This is the "Edict of Killing" (shā lìng)—because autumn and winter are seasons of contraction and killing, executions are carried out.
The "cessation kills" (shā zhǐ) of marriage aligns with the "Taboo of Generation" in spring. Spring forbids killing because spring should be for generation, not killing. Similarly, stopping marriage in spring accords with the principle that spring should be for outward diffusion, not inward convergence (marriage being an act of gathering). Hence, all matters pertaining to autumn and winter (including marriage) must "cease."
Thus, the term "cessation kills" (杀止) does not simply mean "stop"; it implies a gradual reduction and final termination, encompassing the profound thought of seasonal taboos—when the killing/contracting energy of autumn/winter ends and the generative energy of spring begins, all matters belonging to autumn/winter must cease.
Section 2: The Symbolism of "Ice Thawing" and "Thaw"
"Ice Thawing" (冰泮) is not only a physical phenomenon but also a philosophical symbol.
Ice is solidified Water. Water solidifying in winter symbolizes the utmost intensity of Yin energy and the concealment of all things. Ice thawing means ice melts back into water, symbolizing the return of Yang energy and the liberation of all things.
The Yijing, "Release" (解) Hexagram, states:
"Jie (Release). Favorable to the southwest. If one does not go anywhere, but returns, it is auspicious. If one intends to go somewhere, to go early brings auspiciousness." (Yijing 易经·解)
The Jie Hexagram is Thunder over Water—the image of ice and snow melting, and all things being liberated. The Commentary on the Images explains:
"When Heaven and Earth dissolve, thunder and rain arise; when thunder and rain arise, all grains and plants crack open and sprout. How great is the time of Release!"
When the ice of Heaven and Earth melts and thunder and rain emerge, all grains and plants split open. This time of "Release" corresponds exactly to the moment the ice thaws. From the perspective of the Jie Hexagram, when the ice thaws, Heaven and Earth transition from concealment to diffusion, from convergence to release. All matters belonging to concealment and convergence—including marriage—must "release" and cease at this time.
Interestingly, the Jie Hexagram also says, "If one does not go anywhere, but returns, it is auspicious"—there is nothing special one needs to do, it is good to quietly return. This perfectly suits the transitional period after the ice thaws: the old business (marriage) has stopped, the new business (farming) has not fully begun, so this is the time to quietly return and adjust the body and mind to welcome the busy spring.
Section 3: The Consequence of Misplaced Seasonal Edicts
The Book of Rites, "Monthly Ordinances," repeatedly warns that if the governance edict of one season is applied during another, disaster will ensue. This is the concept of "misplaced seasonal execution" (cuò wèi hòu guǒ 错位后果).
For instance, in the third month of autumn:
"If the decree of summer is implemented in late autumn, the state will suffer great floods, winter stores will be damaged and lost, and the people will suffer from nasal ailments. If the decree of winter is implemented, the state will suffer from many bandits and thieves, and border regions will be restless, leading to territorial division. If the decree of spring is implemented, warm winds will arrive, the people’s qi will relax and slacken, and armies will mobilize without resting." (Liji 礼记·月令)
Implementing the spring decree in late autumn—"warm winds will arrive, the people’s qi will relax and slacken." This provides negative evidence for the rationality of "Frost descends, women are wed." If, at the time of Frost's Descent, one implemented the outward diffusion of spring (e.g., being unrestrained in behavior), then "the people’s qi will relax and slacken"—the people's vital essence becomes lax and indolent, which is unfavorable for the solemnity and seriousness required for marriage.
Similarly, in the first month of spring:
"If the decree of autumn is implemented in early spring, the people will suffer a great epidemic. Sudden gales and torrential rains will arrive together, and weeds and thorns will grow side by side. If the decree of winter is implemented, water floods will destroy the crops, and snow and frost will be excessively severe, preventing the first sowing from entering the ground. If the decree of summer is implemented, wind and rain will be untimely, vegetation will fall early, and the state will constantly fear disaster."
Implementing the autumn decree in early spring—"the people will suffer a great epidemic." If marriage rites suitable for autumn are performed in spring, disaster will strike. This also serves as negative evidence for "ice thaws, cessation kills": if marriage does not stop in spring, it violates the Heavenly Dao and invites disaster.
These accounts of "misplaced consequences," though bearing the mystical color of celestial influence on human affairs, possess an underlying logic that is not entirely baseless. The core idea is: human conduct must conform to the timing of Heaven; deviation leads to disorder. Having a time for marriage and moderation for visits accords with the timing of Heaven, leading to fortune; violating the timing of Heaven leads to misfortune. This is the fundamental spirit of the Pre-Qin Monthly Ordinances.
