If your day pillar sits on Gēng (庚 Yang Metal), you meet the world the way unrefined metal meets it: direct, load-bearing, a little blunt. To read a chart built on this Day Master, you translate every other stem into its Ten Gods (十神 shíshén) role — the relationship each element holds to you. That single translation turns ten neutral characters into a story about money, authority, support and self-expression.
This page gives the full set of bazi ten gods for Geng Metal Day Master, then reads each group in ordinary language. Every mapping here is fixed; it does not change with the season or the rest of the chart. What changes is which of these gods you want more of, and that depends on whether your Metal is strong or weak.
The complete Ba Zi Ten Gods for Geng Metal Day Master
The Day Master is Gēng, Yang Metal. Each of the ten Heavenly Stems (天干 tiāngān) is assigned a Ten God role relative to it. Read the table as “when I see this stem, it acts as this god for me.”
| Stem | Ten God |
|---|---|
| Jiǎ 甲 (Yang Wood) | Indirect Wealth (偏财 piāncái) |
| Yǐ 乙 (Yin Wood) | Direct Wealth (正财 zhèngcái) |
| Bǐng 丙 (Yang Fire) | Seven Killings (七杀 qīshā) |
| Dīng 丁 (Yin Fire) | Direct Officer (正官 zhèngguān) |
| Wù 戊 (Yang Earth) | Indirect Resource (偏印 piānyìn) |
| Jǐ 己 (Yin Earth) | Direct Resource (正印 zhèngyìn) |
| Gēng 庚 (Yang Metal) | Friend (比肩 bǐjiān) |
| Xīn 辛 (Yin Metal) | Rob Wealth (劫财 jiécái) |
| Rén 壬 (Yang Water) | Eating God (食神 shíshén) |
| Guǐ 癸 (Yin Water) | Hurting Officer (伤官 shāngguān) |
The logic behind the assignments is the five-element cycle plus polarity. Same element as you is a companion; what you control is wealth; what controls you is power; what produces you is resource; what you produce is output. Same polarity and opposite polarity split each pair into its two flavours.
Companions: Geng and Xin
Metal meeting Metal is your own team. Another Gēng is a Friend — a peer who works the way you do, shoulder to shoulder. Yin Metal Xīn is Rob Wealth, the same strength but a different temperament, and the classic reading is a competitor who reaches for the same resource you do. For a Yang Metal person these companion stars are neither good nor bad on their own. If your chart runs weak, they prop you up so you can hold your wealth and take on responsibility. If it already runs strong, more Metal only crowds the chart and pulls money outward.
Output: Ren and Gui
Metal produces Water, so Water stems are your output — what you make, say and give away. Yang Water Rén is the Eating God, a steady, generous channel: craft, appetite, the pleasure of doing good work at your own pace. Yin Water Guǐ is the Hurting Officer, sharper and more expressive — talent that wants an audience and does not much like being told how. In a Gēng chart, healthy Water softens hard Metal and gives it somewhere to flow. Too much, and the blade dissolves into talk.
Wealth: Jia and Yi
Metal controls Wood, so the Wood stems are your Wealth (财 cái). Yang Wood Jiǎ is Indirect Wealth — the big trunk, opportunistic money, ventures and windfalls. Yin Wood Yǐ is Direct Wealth — the tended plant, salaried and reliable income, and for a man classically the wife star. Gēng is well suited to wealth work: an axe was made to cut timber. But an axe with nothing to chop rusts, and Wood with no Metal to shape it stays wild. Whether you can actually hold this wealth depends on your Metal being strong enough to swing.
Power and Resource: Fire and Earth
Fire controls Metal, so Fire stems are your power — authority, pressure, the officer stars. Yang Fire Bǐng is Seven Killings, raw force that can forge you or scorch you; Yin Fire Dīng is Direct Officer, the disciplined heat that tempers Metal into a proper tool. Ding fire on Geng is a favourite image in the classics precisely because it refines rather than melts.
Earth produces Metal, so Earth stems are your Resource (印 yìn) — support, learning, backing. Yang Earth Wù is Indirect Resource, unconventional knowledge and self-taught depth; Yin Earth Jǐ is Direct Resource, orthodox mentorship and steady nourishment. When Gēng is weak and under pressure from Fire, Earth is what turns that pressure into growth instead of damage. This is why “strong or weak” decides everything about which gods you welcome — start with judging Day Master strength before you rate a single god as good or bad.
Palace position: one god, four verdicts
The pillar holding a god sets its stage in time. Bǐng Seven Killings on the month pillar is the forge running through the formative and working years — the demanding trade, the exacting superior — and it is precisely the pressure a well-earthed Gēng converts into rank. The day branch is the spouse palace, read through hidden stems: a Gēng Chén day pillar keeps Yǐ tucked inside Chén 辰, the Direct Wealth and classical wife star seated in the marriage palace, with the added note that Yǐ and Gēng share a stem combination, so the bond reads close; a Gēng Xū day pillar holds Dīng inside Xū 戌 instead — the refining Direct Officer at home, discipline in the household. And a Rén Eating God on the hour pillar, the palace of output and later life, is the channel that widens with age: the craftsman’s best water flowing in the closing decades.
Reading it in a real chart
Seeing the table is step one; seeing which gods actually sit in your four pillars is step two. A Gēng born with Ding officer close by and Earth resource underneath reads very differently from a Gēng buried in Water output with no Fire to give it shape. For the full concept behind this stem, see the Geng Metal Day Master profile, and to compare assignments across every stem use the master Ten Gods table. The broader system is laid out in Day Masters explained, all ten stems stand side by side in the ten Day Masters guide, the fine blade’s contrasting key is at Xin Metal ten gods, and the competitive cousin discussed above has a deep page at Rob Wealth in Ba Zi.
