Geng Yin·庚寅·Gyeongin
Written by DK
The Geng Yin day pillar, 庚寅 in hanja and 경인 (Gyeongin) in Korean Saju, is a yang Metal day master on a Wood branch. Of the 24,112 庚 charts this site has measured, 4,015 fall on a 庚寅 day. Those read as strong in 31.7 per cent of cases, weak in 46.3 and balanced in 22.1. Taking every 庚 day together the split is 46.6 per cent strong, 32.5 weak and 21.0 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 寅 holds, and what each of those stems is to a 庚 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 庚 |
|---|---|---|---|
| 甲 Yang Wood | 正氣 primary | 16 of 30 | 偏財 Indirect Wealth |
| 丙 Yang Fire | 中氣 middle | 7 of 30 | 七殺 Seven Killings |
| 戊 Yang Earth | 餘氣 residual | 7 of 30 | 偏印 Indirect Resource |
In the twelve-stage cycle a 庚 day master on 寅 sits at 絕 Extinction.
Personality性
Geng (庚), Yang Metal, is unwrought ore and blade — hard, direct, built to cut rather than absorb. In the Geng Yin pillar it sits on Yin (寅), a Wood branch, and the stem-branch relation is control: Metal controls Wood. Unlike a Day Master resting on a branch that feeds or shelters it, this one sits on something it must continually act upon. There is no passive support here, only work. That reading is confirmed by the twelve-stage position: Geng in Yin is at 絕 Extinction, the weakest point in the life cycle, where the old form has fully dissolved and nothing is yet rebuilt. The seat gives no root, no inherited stability — whatever strength this person has, they forge themselves. The hidden stems inside Yin explain what that forging produces. The primary qi, 甲 Jia (Yang Wood, 16 of 30 days), reads as 偏財 Indirect Wealth toward the Day Master — Geng's controlling instinct converts into opportunism, deal-making, a hunger to seize and shape rather than inherit. The middle qi, 丙 Bing (Yang Fire, 7 days), reads as 七殺 Seven Killings — an undertone of combativeness, willingness to meet pressure with pressure, discipline that shows up under threat rather than in comfort. The residual qi, 戊 Wu (Yang Earth, 7 days), reads as 偏印 Indirect Resource — a minor vein of unconventional self-reliance, private study, or instinct that surfaces occasionally but does not anchor the personality the way the other two do.
Career職
With 偏財 Indirect Wealth as the dominant Ten God, work suits enterprise over employment — trading, commission, deal-flow, converting raw opportunity into value, much as an axe converts standing timber into usable material. The 七殺 Seven Killings undertone favors roles with built-in adversity: competitive markets, negotiation, crisis-driven or high-stakes work where the person performs best under real pressure rather than routine. Because the Extinction stage gives no institutional root, career here is rarely inherited or handed down cleanly; it tends to be self-made, often rebuilt more than once. The trace 偏印 Indirect Resource occasionally pulls toward strategy, advisory work, or self-taught expertise, but it is a minor current beside the wealth-and-conflict axis that defines the pillar.
Wealth財
Money is the loudest signal in this chart: 偏財 Indirect Wealth is not just present but dominant, carried by 16 of 30 days in the branch's primary qi. This is wealth earned through activity and timing rather than salary — deal-based, opportunity-driven, comfortable with risk and windfall. There is no 正財 Direct Wealth anywhere in the hidden stems, so the instinct for steady, incremental saving is largely absent; income tends to arrive in bursts tied to initiative rather than in a predictable stream. The nearby 七殺 Seven Killings adds boldness to the spending side as well — money pursued aggressively can be spent just as aggressively.
Love & Compatibility緣
In relationships this is a forceful, decisive presence — Yang Metal that engages by acting on the world rather than waiting to be moved by it, an instinct traceable directly to the controlling stem-branch relation. Generosity often shows through provision and effort, consistent with an Indirect Wealth temperament that expresses care by doing and supplying. The 七殺 Seven Killings undertone brings intensity and occasional combativeness, a tendency to relate through challenge rather than open vulnerability. Because the Day Master sits at 絕 Extinction in its own branch, closeness is not something this pillar arrives with automatically; it has to be built deliberately, and steadier, more settled partnerships are typically constructed rather than simply found.
Best & Worst Pairings合
The strongest matches are 丁亥 (Ding Hai), 乙亥 (Yi Hai), and 己亥 (Ji Hai), each sharing the 亥 branch that forms a Six Harmony with 寅, combining to Wood — precisely the element of Geng Yin's own dominant qi. This harmony reinforces rather than disturbs the wealth theme. Each partner supplies what Geng Yin's own chart lacks: 丁 Ding brings 正官 Direct Officer, lending structure the rootless Extinction stage doesn't provide; 乙 Yi brings 正財 Direct Wealth, the steady counterpart to Geng Yin's windfall-driven Indirect Wealth; 己 Ji brings 正印 Direct Resource, a stabilizing support absent from Geng Yin's own hidden stems. All three sit at 病 Sickness themselves, so the match is complementary rather than overpowering. The weakest matches are 丙申 (Bing Shen), 甲申 (Jia Shen), and 戊申 (Wu Shen), each carrying 申, which clashes directly with 寅. This uproots the one relation Geng Yin's wealth structure depends on, and because all three sit at 臨官 Establishment — near peak strength — the clash lands at full force. 丙申 doubles the latent 七殺 Seven Killings pressure into open conflict; 甲申 mirrors Geng Yin's own 偏財 Indirect Wealth, turning shared resource-instinct into rivalry rather than support; 戊申 echoes the minor 偏印 trace but at clash-strength, destabilizing rather than assisting.
