Geng Xu·庚戌·Gyeongsul
Written by DK
The Geng Xu day pillar, 庚戌 in hanja and 경술 (Gyeongsul) in Korean Saju, is a yang Metal day master on a Earth branch. Of the 24,112 庚 charts this site has measured, 4,026 fall on a 庚戌 day. Those read as strong in 69.6 per cent of cases, weak in 11.6 and balanced in 18.8. 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 戌 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 |
|---|---|---|---|
| 戊 Yang Earth | 正氣 primary | 18 of 30 | 偏印 Indirect Resource |
| 丁 Yin Fire | 中氣 middle | 3 of 30 | 正官 Direct Officer |
| 辛 Yin Metal | 餘氣 residual | 9 of 30 | 劫財 Rob Wealth |
In the twelve-stage cycle a 庚 day master on 戌 sits at 衰 Decline.
Personality性
Geng Xu is Yang Metal — 庚, the ore-hard, unforged blade — sitting on a branch that generates it: 戌 Xu is Earth, and 'Metal generated by Earth' is the pillar's whole architecture in one phrase. The branch's primary hidden stem is 戊 Yang Earth, holding 18 of the branch's 30 days and expressing as 偏印 Indirect Resource toward the Day Master — the dominant force of this pillar. Indirect Resource built this deep gives Geng Xu people a self-contained mind: they trust knowledge they gathered themselves — unconventional, specialist, or private — over what an institution certified. Underneath that, a residual 辛 Yin Metal (9 days) reads as 劫財 Rob Wealth, a same-element sibling-self influence that hardens the temperament into something territorial and competitive, unwilling to concede ground to rivals. A trace 丁 Yin Fire (3 days) contributes 正官 Direct Officer — only 3 days of weight, so it is a thin undercurrent of duty and propriety rather than a governing trait, but it is there, waiting to be activated. The Day Master itself sits at 衰 Decline in this branch: strong, but past the raw combative peak of a stage like Emperor. The result is restrained power — dignified, economical with effort, more interested in consolidating what it holds than conquering new ground.
Career職
The dominant 偏印 Indirect Resource points this pillar toward self-directed expertise rather than credentialed hierarchy: technical trades, engineering, specialist consulting, craftwork tied to Metal, or any field where mastery is proven by output rather than pedigree. The residual 劫財 Rob Wealth favors work with built-in rivalry — freelance practice, sales, or trades where success is measured against direct competitors — since this pillar is comfortable contending for position. The trace 正官 Direct Officer, though only 3 days of weight on its own, matters because both of Xu's branch relations gather toward Fire: the 三合 three harmony with 寅 and 午 gathers Fire, and the 六合 six harmony with 卯 also transforms to Fire. Fire is this Day Master's Officer element, so circumstance and the right colleagues can pull a Geng Xu person into real institutional authority even though the branch alone only hints at it. Decline stage argues against chasing early aggressive expansion; this pillar performs best in consolidative, senior, or advisory positions — refining and maintaining rather than founding.
Wealth財
None of Xu's three hidden stems is a wealth god — no 正財 Direct Wealth, no 偏財 Indirect Wealth appears anywhere in the branch. That absence is the wealth story here: money is not generated directly by this pillar's own structure, only mediated through it. Income tends to arrive via the resource channel — skill, expertise, or independent means converted into earnings — rather than through commerce or venture. The residual 劫財 Rob Wealth adds a second complication: wealth is prone to being shared, contested, or actively taken by peers and rivals, so joint ventures and partnerships around money carry more friction than they promise. Without a wealth god of its own, this pillar tends to guard resources rather than aggressively grow them, and its risk is losing ground to competitors rather than losing to bad investment.
Love & Compatibility緣
In relationships, Geng Xu brings the same qualities that define the chart: quiet, seasoned strength rather than heat, and a guardedness that comes directly from a personality built on Indirect Resource — self-sufficient, privately-run, slow to open its interior life to a partner. The residual Rob Wealth streak can turn a partner into an unconscious rival, especially over shared resources or attention, making open sharing harder than it should be. The trace Direct Officer supplies a small, real capacity for commitment and duty, but at only 3 days of weight it is not enough on its own to soften the self-protective core. What this pillar finds difficult is emotional transparency and easy merging; what it offers instead is loyalty that does not need to be renewed by validation, because its sense of self was never dependent on the relationship to begin with.
Best & Worst Pairings合
The strongest matches are 丁卯 Ding Mao, 乙卯 Yi Mao, and 己卯 Ji Mao, each sharing the branch 卯 Mao, which stands in 六合 six harmony with Xu and transforms the pairing toward Fire — precisely the element that sits as a mere 3-day trace inside Xu's own hidden stems. All three arrive at the 胎 Embryo stage toward Geng, a formative rather than confrontational position, meaning these unions tend to grow the person rather than test them. 丁卯's stem is 正官 Direct Officer, reinforcing the discipline already latent in the chart; 乙卯's stem is 正財 Direct Wealth, supplying the wealth structure this pillar otherwise lacks entirely; 己卯's stem is 正印 Direct Resource, adding an orthodox, legitimate resource channel alongside the unconventional Indirect Resource base. The worst matches are 丙辰 Bing Chen, 甲辰 Jia Chen, and 戊辰 Wu Chen, all sharing the branch 辰 Chen, which stands in direct 沖 clash with Xu — two Earth storage branches destabilizing each other. 丙辰 carries 七殺 Seven Killings, unmediated authority pressure the chart's thin Officer trace cannot soften, making it the harshest of the three. 甲辰 carries 偏財 Indirect Wealth, so the clash unsettles wealth just as it might arrive. 戊辰 carries 偏印 Indirect Resource — the same god that dominates Xu's own chart — but rather than reinforcing it, the clash destabilizes the very resource base Geng Xu depends on most.
