Yi Wei·乙未·Eulmi
Written by DK
The Yi Wei day pillar, 乙未 in hanja and 을미 (Eulmi) 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 乙未 day. Those read as strong in 38.6 per cent of cases, weak in 39.2 and balanced in 22.2. 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 未 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 |
| 乙 Yin Wood | 中氣 middle | 3 of 30 | 比肩 Friend |
| 丁 Yin Fire | 餘氣 residual | 9 of 30 | 食神 Eating God |
In the twelve-stage cycle a 乙 day master on 未 sits at 養 Nurture.
Personality性
Yi Wood is the pliant 'grass and vine' Wood, yielding to obstacles rather than pushing through them the way Jia Wood does. Yet the Yi Wei pillar sits on a branch, Wei (Earth), that Wood controls — the Day Master's own seat is built from the very element it acts upon. That relationship means the person is rooted in resource and gain from birth: the branch's primary hidden stem, Ji Earth (Yin Earth) at 18 of the branch's 30 days, expresses as 偏財 Indirect Wealth toward the Day Master — the dominant influence of the whole pillar. Indirect Wealth read into personality gives a practical, exchange-minded disposition: comfort with fluid gain, an instinct to convert effort or relationships into value, and an ease with unpredictability that a Direct Wealth nature would find unsettling. Layered above that, at 9 of 30 days, is Ding Fire (Yin Fire), the residual qi, read as 食神 Eating God — the drive to make, express, and enjoy: craft, cooking, teaching, quiet creative output. Only 3 of 30 days belong to Yi Wood itself, read as 比肩 Friend, a faint trace of self-support and peer kinship, not enough to anchor an assertive ego. The Day Master's own twelve-stage position here is Nurture (養) — the stage of gestation just before birth, sheltered, dependent, still forming. Together these features describe someone whose character rests less on self-assertion than on patient, protected accumulation — a personality still growing into its own strength.
Career職
Because Indirect Wealth is the pillar's dominant Ten God, the work that suits this Day Master is rarely salaried and linear. Indirect Wealth favours trade, commission, consulting, land or resource management, and entrepreneurial ventures where income arrives in variable amounts through opportunity rather than fixed contract. The Eating God, Ding Fire, sharpens this further: in the five-element cycle Fire produces Earth, so the pillar's output — craft, teaching, cooking, writing, any form of personal creative expression — feeds directly into its wealth line rather than sitting apart from it. Career paths that let expression itself become the income suit this structure precisely. The Nurture stage adds a further condition: growth here favours mentorship, apprenticeship, or institutional backing before independence — the ability to earn tends to mature slowly, under support, rather than erupting fully formed.
Wealth財
The wealth relationship is not incidental to this pillar — it is its substance. Ji Earth, the primary hidden stem occupying 18 of the branch's 30 days, is 偏財 Indirect Wealth, and no Direct Wealth (正財) stem appears among the hidden stems at all. That absence matters: this is a person for whom money moves rather than settles, arriving through venture, trade, or opportunity rather than fixed salary, and who is constitutionally more at ease with variable income than with the discipline of steady accumulation. Because the Eating God, Ding Fire, produces this Indirect Wealth in the five-element sequence, income here is naturally self-generated — a product of personal output and skill rather than external allocation. Gain comes easily when effort is expressed outward; it stalls when the person is asked simply to hold a position and wait for wealth to accrue on its own.
Love & Compatibility緣
Yin Wood's natural mode in relationship is accommodation — bending toward a partner's shape rather than insisting on its own. The Eating God's presence, Ding Fire, brings warmth and an appetite for shared pleasure — food, comfort, quiet domestic ritual — making this a temperament well suited to sustained companionship rather than dramatic courtship. Because Indirect Wealth dominates the pillar, closeness is often expressed through generosity and reciprocity — giving and being given to as a form of care — rather than through direct declaration. The difficulty lies in the Nurture stage itself: this is a Day Master still gestating its own strength, and it can lean on a partner for stability before it has built an independent footing. With only a trace of Friend (比肩) to anchor self-support, the pull toward accommodation can run further than is healthy, making boundary-setting the harder half of intimacy for this pillar.
Best & Worst Pairings合
The best matches share the branch Wu (午), which forms a six harmony with Wei and transforms the pair toward Earth — a binding, cooperative fit that steadies rather than unsettles. Each of these partners also occupies the 長生 Birth stage, fresh vital energy that lends the still-gestating Yi Wei pillar real forward motion. 壬午 Ren Wu carries 正印 Direct Resource to the Day Master, offering exactly the sheltering support a Nurture-stage growth needs. 庚午 Geng Wu carries 正官 Direct Officer, lending structure and discipline to counterbalance the pillar's fluid, opportunistic Indirect Wealth nature. 戊午 Wu Wu carries 正財 Direct Wealth, supplying the fixed, steady counterpart to a wealth relationship that is otherwise entirely indirect. The worst matches share the branch Chou (丑), which clashes with Wei, unsettling the gathering the Nurture stage depends on; each also sits at the waning 衰 Decline stage, offering little vitality to draw on. 辛丑 Xin Chou brings 七殺 Seven Killings, a direct and pressuring conflict. 癸丑 Gui Chou brings 偏印 Indirect Resource, support that arrives unpredictably. 己丑 Ji Chou repeats the pillar's own 偏財 Indirect Wealth through a clashing branch, turning shared resource-mindedness into rivalry rather than cooperation.
