Origins and Foundations of the Ziping Method
子平法源
Original Text 原文
天地之間,人稟五行之氣而生。 欲知禍福,先察陰陽之理。 古法以年為主,未盡精微。 子平先師,獨取日干為主, 配以月令,參之時日, 四柱八字,體用分明。 蓋日干者,一身之主宰也。 年為根本,月為提綱, 日為己身,時為歸宿。 四柱排定,五行生剋制化, 十神變化,格局自成。 此法一出,前人舊法盡廢, 命理之學,煥然一新矣。 夫命者,天地人三才之道也。 年柱為祖上之基,月柱為父母之宮, 日柱為己身配偶,時柱為子女後運。 四柱之中,日干最要。 日干旺衰,關乎一生之榮枯。 月令司權,定格局之高低。 此子平法之大旨也。
Translation 譯文
Between Heaven and Earth, human beings are born receiving the Qi of the Five Elements.
To know fortune and misfortune, first examine the principles of Yin and Yang.
The ancient methods took the Year Pillar as primary, but could not exhaust the subtleties of fate.
Master Ziping alone took the Day Stem as the focal point,
Matching it with the Month Command, cross-referencing with the Hour and Day.
The Four Pillars and Eight Characters — Substance and Function become clear.
For the Day Stem is the sovereign ruler of one's entire being.
The Year is the root and foundation; the Month is the guiding principle;
The Day is oneself and one's spouse; the Hour is the final destination.
Once the Four Pillars are arranged, the Five Elements interact through generation, conquest, control, and transformation.
The Ten Gods transform and shift, and structural patterns form naturally.
When this method emerged, the old methods of the ancients were entirely superseded,
And the study of fate-calculation was utterly renewed.
Fate is the Way of the Three Powers: Heaven, Earth, and Humanity.
The Year Pillar is the foundation of ancestors; the Month Pillar is the palace of parents;
The Day Pillar is oneself and one's spouse; the Hour Pillar is children and later fortune.
Among the Four Pillars, the Day Stem is paramount.
The vigour or decline of the Day Stem governs the prosperity or withering of an entire life.
The Month Command holds authority and determines the height of one's structural pattern.
This is the great thesis of the Ziping method.
Key Concepts 核心概念
- 日干 (Rì Gān)
- Day Stem — the Heavenly Stem of the Day Pillar, representing the self. Xu Ziping's revolutionary contribution was making this the absolute focal point of all chart analysis, replacing the older Year Pillar-centric method.
- 月令 (Yuè Lìng)
- Month Command — the Earthly Branch of the Month Pillar, which determines the seasonal Qi environment of the chart. It is the single most important factor in establishing the structural pattern (格局) of the chart.
- 四柱八字 (Sì Zhù Bā Zì)
- Four Pillars, Eight Characters — the Year, Month, Day, and Hour pillars, each consisting of one Heavenly Stem and one Earthly Branch, totalling eight characters that encode the cosmic moment of birth.
- 體用 (Tǐ Yòng)
- Substance and Function — a philosophical framework in which the Day Master is the Substance (體, the self) and the other elements in the chart serve as Function (用, the external world acting upon the self).
- 十神 (Shí Shén)
- Ten Gods — the ten relationships between the Day Master and the other Stems/Branches: Direct Officer, Seven Killing, Direct Resource, Indirect Resource, Eating God, Hurting Officer, Direct Wealth, Indirect Wealth, Friend, and Rob Wealth.
Commentary 評注
This opening chapter establishes the historical and theoretical foundation of the entire Yuan Hai Zi Ping system. Before Xu Ziping, Chinese fate-calculation primarily used the Year Pillar (年柱) as the reference point — a method associated with Li Xuzhong (李虛中) of the Tang Dynasty. Li Xuzhong's approach, while groundbreaking for its time, could only paint the destiny of an entire birth year cohort with broad strokes.
Xu Ziping's innovation was both simple and profound: by shifting the focal point to the Day Stem (日干), he created a system capable of distinguishing between individuals born in the same year, month, and even day. The Day Stem became the tai ji (太極) — the absolute centre from which all other chart relationships radiate outward.
The concept of Month Command (月令) as the "guiding principle" (提綱) is equally important. The Month Branch determines which element holds seasonal authority at the time of birth — this seasonal context shapes everything. A Jia Wood (甲木) Day Master born in spring (when Wood is in season) is fundamentally different from one born in autumn (when Metal, the conqueror of Wood, holds power).
The Four Pillars are arranged in a specific hierarchy of meaning: Year relates to ancestry and early childhood; Month to parents, education, and the social environment of youth; Day to the self and marriage; Hour to children and the trajectory of later life. This layered reading allows the practitioner to trace the arc of an entire life from a single chart.
