Xin You·辛酉·Sinyu
Written by DK
The Xin You day pillar, 辛酉 in hanja and 신유 (Sinyu) in Korean Saju, is a yin Metal day master on a Metal branch. Of the 24,101 辛 charts this site has measured, 4,015 fall on a 辛酉 day. Those read as strong in 72.7 per cent of cases, weak in 9.1 and balanced in 18.2. Taking every 辛 day together the split is 53.3 per cent strong, 26.4 weak and 20.3 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 酉 holds, and what each of those stems is to a 辛 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 辛 |
|---|---|---|---|
| 辛 Yin Metal | 正氣 primary | 20 of 30 | 比肩 Friend |
| 庚 Yang Metal | 餘氣 residual | 10 of 30 | 劫財 Rob Wealth |
In the twelve-stage cycle a 辛 day master on 酉 sits at 臨官 Officialdom.
Personality性
Xin You pairs a Yin Metal Day Master with You, the Rooster branch, which is itself pure Metal — the branch's own element matching the stem exactly, with no room for other elements to intrude. The two hidden stems, Geng (Yang Metal, residual qi, holding 10 of the branch's 30 days, expressing as 劫財 Rob Wealth) and Xin itself (Yin Metal, primary qi, holding 20 days, expressing as 比肩 Friend), are both faces of Metal and both belong to the "self" domain of the Ten Gods — Friend and Rob Wealth describe the Day Master's relationship to its own kind, not to wealth, authority, nurture, or expression. This is one of the few branches among the sixty pillars where every hidden stem is the same element as the stem sitting on it; there is no Wood, Fire, Water, or Earth anywhere in the pillar. The result is an unusually concentrated, self-referential identity. Sitting in 臨官 Officialdom, the life-cycle stage of a young official who has earned real standing but has not yet reached the overreach of 帝旺 Emperor, the Day Master carries settled competence rather than untested ambition. Yin Metal in its own seat, doubled by Friend and shadowed by Rob Wealth, produces someone precise, self-possessed, and quietly competitive — defined by comparison to peers rather than by service to an outside standard, since no Officer stem is present to impose one. Refinement, Yin Metal's own nature as jewelry rather than ore, sits alongside an edge that does not easily bend.
Career職
With Friend dominant and Rob Wealth secondary — both peer-facing Ten Gods — and no Officer, Resource, or Output among the hidden stems, this pillar suits work where competence is self-certified rather than institutionally conferred: independent practice, competitive fields, precision trades that reward individual judgment — editing, appraisal, law, surgery, finance trading, skilled metalwork — anywhere Metal's discernment, cutting the accurate from the approximate, is the product. Officialdom stage supplies genuine capacity to hold a post and perform it well, but because nothing in the branch generates 正官/七殺 Officer energy, the drive to occupy formal hierarchy has to be built rather than assumed; this Day Master tends toward self-employment, partnership, or guild-like peer structures over strict chains of command, and does well wherever standing among equals, not a superior's approval, is the measure of success.
Wealth財
正財 Direct Wealth and 偏財 Indirect Wealth are both absent from You's hidden stems — this branch generates no wealth god at all. What it offers instead is 劫財 Rob Wealth, the Ten God that specifically describes money contested, shared, or taken among peers. Together these facts describe someone for whom earning is not a built-in feature of temperament; resources have to be pursued deliberately, through skill converted to value, rather than accruing as a natural byproduct of the personality the way they might for a Day Master rooted over a Wealth stem. Rob Wealth's presence also carries a practical caution: partnerships, joint ventures, and peer-level financial entanglements are the likeliest place money slips away, since the pillar's own energy is built for rivalry and alliance among equals, not for accumulation.
Love & Compatibility緣
The same Friend-and-Rob-Wealth temperament that shapes career and money shapes intimacy: loyalty to those treated as equals, directness, a refined and exacting aesthetic sense — Yin Metal is ornament rather than raw ore, and this shows in taste and self-presentation — but also a habit of measuring a relationship the way a peer measures a rival, tracking fairness and standing even where warmth is intended. Vulnerability is difficult; Metal in this doubled, unmixed form does not yield easily, and without a Resource or Output stem in its own branch to soften or express feeling outward, affection can be real but understated, delivered as loyalty and reliability rather than open display. What this temperament needs from a partner is warmth and give that it does not generate for itself.
Best & Worst Pairings合
The three best matches — 丙辰 Bing Chen, 戊辰 Wu Chen, and 甲辰 Jia Chen — all share the same mechanism: Chen forms a 六合 Six Harmony with You that transforms to Metal, so the pairing reinforces the Day Master's root rather than diluting it, while each stem supplies exactly what Xin You's own branch withholds. Bing Chen brings 正官 Direct Officer, the structure and legitimate authority missing from a branch built entirely of Friend and Rob Wealth. Wu Chen brings 正印 Direct Resource, the nurture and support this self-referential pillar cannot generate internally. Jia Chen brings 正財 Direct Wealth, filling the exact gap the wealth section describes. All three stems sit at 墓 Tomb in Chen, so what they offer arrives stored and steady rather than showy — banked authority, banked support, banked money. The three worst matches — 丁卯 Ding Mao, 辛卯 Xin Mao, and 己卯 Ji Mao — all share Mao, which stands in direct 沖 Clash with You, uprooting the Day Master's own seat regardless of the stem riding on it, and all three fall at 絕 Death, the life-cycle stage of extinguishment. Ding Mao adds 七殺 Seven Killings on top of the clash, the most severe of the three; Xin Mao doubles the Day Master's own Friend energy into open rivalry; Ji Mao offers 偏印 Indirect Resource that a clashed branch turns erratic rather than nourishing.
