壬 (Ren, Rén, “Yang Water (Six Yi)”) is one of the 9 Stems (三奇六儀) of Qi Men Dun Jia — one of the Six Yi (六儀), the ‘instrument’ stems that conceal the original 甲 leader stem during chart construction. The fifth Yi 壬 — yang water, conceals 甲辰, flowing wealth; supports large-scale and oceanic undertakings.
壬: classical reading and register
壬 (yang water) is one of nine stems used in Qi Men Dun Jia chart construction. The Three Wonders (乙 / 丙 / 丁) are the most-favourable stems and represent classical 'wonder' registers (Sun, Moon, Star); the Six Yi (戊 / 己 / 庚 / 辛 / 壬 / 癸) are the 'instrument' stems that conceal the original Heavenly Stem 甲 during chart casting.
Classical attributes
Category: 六儀 (six yi)
Yi role:壬儀 (隱甲辰) (Fifth Yi (hides 甲辰))
Element: yang water
Tier: neutral
Domain: The fifth Yi instrument; conceals 甲辰; flowing wealth, large-scale movement, oceanic register
Positive register
Flowing wealth, large-scale undertakings, situations requiring fluid adaptation, oceanic / large-water-related projects (shipping, fishing, water-based business). The yang water is broad and deep rather than narrow and fast.
Negative register
Floods (literal or metaphorical), wealth that arrives but doesn't stay, situations where the flow overwhelms the container. Inauspicious when the flow is unmanaged.
When to consult 壬
Read carefully — 壬 is the broad / flowing member of the Six Yi. Favourable for large-scale, oceanic, or wealth-flow questions; warning when the flow needs containment.
Practical priorities
壬 as one of the Six Yi carries a more neutral register that depends substantially on the surrounding pattern.
Read the stem alongside the gate / star / spirit / palace sharing its location. Stems modulate; the surrounding components determine activation.
The fifth Yi 壬 — yang water, conceals 甲辰, flowing wealth; supports large-scale and oceanic undertakings. It is one of the Six Yi (六儀), the instrument stems that conceal the original 甲 leader stem during chart casting.
What's the difference between the Three Wonders and the Six Yi?
The Three Wonders (三奇: 乙 / 丙 / 丁) are the favourable stems classically associated with Sun / Moon / Star registers — wonders of celestial brilliance. The Six Yi (六儀: 戊 / 己 / 庚 / 辛 / 壬 / 癸) are the instrument stems used during chart casting; they conceal the six 甲 leader stems (甲子 / 甲戌 / 甲申 / 甲午 / 甲辰 / 甲寅) under their respective 戊 / 己 / 庚 / 辛 / 壬 / 癸 covers. The original 甲 is never directly visible in the chart — it operates through its concealing yi.
Should I look for 壬 specifically in my consultation?
Read carefully — 壬 is the broad / flowing member of the Six Yi. Favourable for large-scale, oceanic, or wealth-flow questions; warning when the flow needs containment.
