Geng Metal Day Master: what it is and how to read it
Geng is Yang Metal: hard and in need of forging, it takes Fire when strong and Earth when weak. To read a Geng Day Master, check whether autumn has made it too strong or summer Fire has left it weak, then choose Fire, Earth or Water. Climate is only a repair.

What does Geng’s hardness mean?
Yang Metal resists: Geng stands up to Fire and rarely follows, so the bar for a follow pattern is higher than for Xin.
Geng’s Lu is Shen and its Growth stage is Si; it combines with Yi and clashes with Jia. Jia is its Indirect Wealth, so the clash often reads as friction over money.
Autumn Geng: over 90% strong
In Shen, You and Xu months Metal rules: 94.5% of autumn Geng charts are strong, none weak. Strong Metal needs control or draining: Fire (Officer) 55.9%, Wood (Wealth) 29%, Water (output) 15.2%.
Adding Earth or Metal here only makes it stiffer.
Why does summer Geng take Earth, not Water?
Summer Fire controls Metal: 62.7% of summer Geng are weak, 53.6% take Earth, only 9.2% Water. Weak Geng first needs Resource (Earth) to turn Fire into support; Water cools but drains weak Metal further.
That is strength leading: climate seems to call for Water, strength calls for Earth first.
Two real charts
Yi Mao · Gui Wei · Geng Wu · Ding Chou (female, 23 Jul 1975, 02:30, Beijing)
Geng is born in Wei, late summer; Wu and Ding control it and Yi Mao and Gui drain it, but Wei and Chou earth feed it, so the chart is balanced. With no clear strength direction, climate repair decides: the calculator uses Fire, favours Wood and Metal and names no unfavourable element.
Yi Si · Ji Mao · Geng Shen · Ji Mao (male, 7 Mar 1965, 06:15, Beijing)
Geng is born in Mao, spring, with two Mao (Wealth) and Si controlling it; only the Shen branch roots it, so Geng is somewhat weak. The calculator uses Metal (Friends) to carry the Wealth, favours Earth and Fire and marks Water and Wood unfavourable. Fire, the climate hint, stays favourable only.
Data: what does Geng need in autumn and summer?
Our sample has 627 Geng Day Masters. Of 145 born in autumn, 94.5% are strong and 55.9% take Fire.
Of 153 born in summer, 62.7% are weak: Earth 53.6%, Fire 21.6%, Water only 9.2%. Only 2.4% of Geng charts are special patterns, the lowest of all stems: Yang Metal rarely follows.
Sample: 6,000 charts cast with our own engine (birth years 1950–2010 uniformly random, random birth time, half male/half female, Beijing true solar time, fixed seed 20261014, reproducible). Seasons by month branch: Yin–Mao–Chen spring, Si–Wu–Wei summer, Shen–You–Xu autumn, Hai–Zi–Chou winter.
Common view vs. our view
| Common view | Our view | Why |
|---|---|---|
| Summer Geng takes Water first | Check strength; weak Geng takes Earth | Summer Geng: Earth 53.6%, Water 9.2% |
| Geng fears Fire | Strong Geng needs Fire as Officer | Autumn Geng: 94.5% strong, 55.9% take Fire |
| Yi–Geng always transforms into Metal | Usually just a tie | Transformation needs the month and the whole chart |
Common mistakes
- Geng is a blade, so Geng people are blunt and tough: personality comes from the Ten Gods.
- Summer Geng always takes Water to cool down: 53.6% take Earth.
- Bing and Ding melt Geng: strong Geng needs Fire to forge it.
FAQ
How is Geng different from Xin?
Both are Metal: Geng is Yang and hard, forged by Fire when strong; Xin is Yin and fine, fears being buried by Earth and likes Water.
What does the Jia–Geng clash mean?
Jia is Geng’s Indirect Wealth, so the clash often shows as money pulling in two directions. How hard it hits depends on roots and the month.
Which element does a Geng Day Master need most?
Strong autumn Geng usually takes Fire or Wood; weak summer Geng Earth; winter Geng mostly Fire. Use the chart page result.
What does the Yi–Geng combination mean for Geng?
Yi is Geng’s Direct Wealth: attention tied up by Wealth, often linked to a partner in a man’s chart. Transformation depends on the month.
