The basics
Yi-Si day pillar, NaYin image "覆灯火". The stem Yi is Wood, the branch Si is Fire hiding 3 stem(s) whose Ten Gods read Hurting Officer, Seven Killings, Indirect Wealth; the branch maps to the Snake. Yi Wood — vine and flower: flexible and empathetic, thriving by adapting and cooperating.
Personality
The main hidden stem 丙 reads as Hurting Officer beneath the Day Master — no primary root beneath the seat: a more flexible, adaptive personality. Officer under the seat: responsible and self-demanding. Wealth under the seat: pragmatic and results-oriented. Output under the seat: expressive and creative.
Career & wealth
With a Yi Wood Day Master: Brilliant and unfiltered: creative, persuasive and allergic to micromanagement — aim the edge at work, not at people. Element-wise, industries of your favorable elements fit best — as a rule of thumb, education, publishing, healthcare and growth sectors.
Marriage
The day branch 巳 is the spouse palace, hiding 丙 (Hurting Officer). You love with wit and intensity; a partner who can take a joke and give honesty thrives with you. A full marriage reading weighs all four pillars and the luck pillars.
Ideal partner (male chart)
For a male chart with a 乙 Wood Day Master, the spouse star is the wife star (what you control): the 土 element. Wood-partner warmth, Fire-partner energy, Earth-partner steadiness, Metal-partner principles, Water-partner wit — whichever matches. The spouse palace 巳 harmonizes with Monkey and gets along naturally with Rooster & Ox.
Ideal partner (female chart)
For a female chart with a 乙 Wood Day Master, the spouse star is the husband star (what controls you): the 金 element. The matching stem suggests whether your ideal partner leads with structure (Metal/Water) or warmth (Wood/Fire). The spouse palace 巳 combines with Monkey; the clash branch 亥 (Pig) needs more patience — workable, just more effortful.
