Yi Chou·乙丑·Eulchuk
Written by DK
The Yi Chou day pillar, 乙丑 in hanja and 을축 (Eulchuk) in Korean Saju, is a yin Wood day master on a Earth branch. Of the 24,101 乙 charts this site has measured, 4,015 fall on a 乙丑 day. Those read as strong in 19.3 per cent of cases, weak in 66.3 and balanced in 14.4. Taking every 乙 day together the split is 31.9 per cent strong, 47.9 weak and 20.2 balanced.
The figures come from running this site’s engine over every day of the stem from 1950 to 2009, with a birth in Seoul every two hours from two in the morning to ten at night. Midnight is left out: once Seoul’s clock is corrected for its longitude, a midnight birth falls on the day before, which carries a different stem.
Structure藏干
What the branch 丑 holds, and what each of those stems is to a 乙 day master. The day counts are the classical weights within a thirty-day month, main stem first.
| Hidden stem | Qi | Days of 30 | Ten God to 乙 |
|---|---|---|---|
| 己 Yin Earth | 正氣 primary | 18 of 30 | 偏財 Indirect Wealth |
| 辛 Yin Metal | 中氣 middle | 3 of 30 | 七殺 Seven Killings |
| 癸 Yin Water | 餘氣 residual | 9 of 30 | 偏印 Indirect Resource |
In the twelve-stage cycle a 乙 day master on 丑 sits at 衰 Decline.
Personality性
Yi Chou places pliant Yin Wood — the vine or grass, not the trunk — directly atop Chou, an Earth branch it controls. Because Wood controls Earth, the branch beneath the Day Master is structurally Wealth, and its primary hidden stem, Ji Earth (己, 18 of 30 days), expresses as 偏財 Indirect Wealth. This is the substance of the pillar: a nature organized from the ground up around acquiring, converting, and managing material resource, with Indirect Wealth's characteristic comfort with irregular, opportunistic gain rather than fixed income. The residual stem, Gui Water (癸, 9 days), reads as 偏印 Indirect Resource — an unconventional, self-taught, intuitive layer that keeps the wealth-drive from being purely mercenary, giving it private reflection and unorthodox learning underneath the practicality. A trace of Xin Metal (辛, 3 days) carries 七殺 Seven Killings, a capacity for hardness or decisive authority so thinly present it rarely shows except under real pressure. Sitting at Decline (衰) in the twelve-stage cycle, this Day Master has already passed its phase of vigorous outward growth; it operates with a gardener's patience — steady, unshowy, disinclined to gamble energy on sudden expansion, favoring the slow tending of what has already taken root.
Career職
With Indirect Wealth as the dominant god, this pillar suits work with direct exposure to resource flow rather than salaried administration — trading, brokering, property, inventory, deal-based commerce, anything built on turning opportunity into gain. The Indirect Resource trace favors expertise gained outside formal channels: self-taught trades, appraisal, informal apprenticeship. The faint Seven Killings gives an occasional capacity for tough, decisive action, useful in crisis or negotiation but not a constant register. Decline argues against careers that demand rapid ascent; this pillar peaks through accumulated judgment over decades — long-run consultancy, land or resource management, and trades where hard-won experience is the actual product.
Wealth財
Wealth here is earned, not inherited or drawn as steady pay — the branch's primary qi is 偏財 Indirect Wealth, and no 正財 Direct Wealth appears among the hidden stems at all. Because the Day Master itself controls the branch (Wood over Earth), resource is something actively grasped and worked rather than passively stewarded; income tends to be lumpy, opportunistic, tied to initiative rather than salary structure. Fixed-paycheck security feels confining to this configuration. Decline moderates the risk, though — gains once made are consolidated carefully rather than spent or gambled, producing a pattern of cautious, compounding accumulation rather than speculative swings.
Love & Compatibility緣
Yi Wood is naturally accommodating and diplomatic, but because the whole foundation of this pillar is organized as Wealth, affection tends to be expressed through practical provision and quiet management rather than open declaration. The Indirect Resource trace gives a private, intuitive inner life that is not always shared readily, and the Seven Killings trace surfaces only when boundaries are truly tested, producing an otherwise easygoing temperament with an occasional hard edge. The difficulty is a reserved, non-effusive style of care, shaped by Decline's preference for steadiness over spontaneity — partners who read restraint as coldness will misjudge what is, underneath, patient and provisioning devotion.
Best & Worst Pairings合
The strongest matches are 壬子 Ren Zi, 庚子 Geng Zi, and 戊子 Wu Zi, all sharing a Six Harmony between Chou and Zi that transforms to Earth, reinforcing rather than fighting this pillar's wealth-based foundation. Each supplies something Yi Chou lacks alone: Ren Zi's 正印 Direct Resource offers legitimate support and nurture, Geng Zi's 正官 Direct Officer brings structure and sanctioned authority, and Wu Zi's 正財 Direct Wealth supplies the steady income the pillar's Indirect Wealth otherwise never provides. All three sit at the Sickness (病) stage, a delicate, interdependent phase in which the pairing works through mutual tenderness rather than raw strength. The worst matches are 辛未 Xin Wei, 癸未 Gui Wei, and 己未 Ji Wei, each clashing Chou directly against Wei and destabilizing the very branch the Day Master is rooted in. Xin Wei compounds the clash with 七殺 Seven Killings, producing the sharpest conflict of the three; Gui Wei and Ji Wei clash while duplicating the pillar's own Indirect Resource and Indirect Wealth qi, amplifying friction rather than offering anything new. All three sit at the early, undeveloped Nurturing (養) stage, meeting the clash without the maturity to absorb it easily.
