Geng Yin · 庚寅
Geng Yin pairs a Yang Metal Day Master with 寅 (the Tiger), a Wood branch. If this is your day pillar, the pairing below describes tendencies worth observing — not a verdict.
The Day Master on top
Yang Metal · 庚 — The classical image for 庚 is raw metal — the axe, the ore: force that resolves things by cutting. A Yang Metal Day Master tends to prefer the decisive version of any question: keep or drop, yes or no, now or never.

In a day pillar, the branch is read as the spouse palace: the texture of close partnership. 寅 (the Tiger) carries these hidden stems, each read as a relationship between that stem and your Day Master:
甲
Indirect Wealth
Indirect wealth — opportunity money, deals, and resources that move through networks.
丙
Pressure
Pressure without the soft title — urgency, rivals, and hard edges that demand response.
戊
Indirect Resource
Indirect resource — unconventional learning, odd mentors, and support that arrives sideways.
Na Yin
The Na Yin of Geng Yin is 松柏木 — "Pine-and-Cypress Wood". Na Yin is a poetic sixty-fold naming of the pillars, used as a secondary texture rather than a primary verdict.
Stage of the cycle
Void — Empty reset — little support; the cycle is between endings and beginnings.
Void branches (Xun Kong)
Charts anchored on 庚寅 treat 午未 as "void" — branches whose signals are read as weakened or delayed rather than absent.
Is Geng Yin actually your day pillar?
The day pillar comes from your exact birth date — and near midnight, from true solar time. Calculate it instead of guessing.
As with everything on Truenoon, this page describes observable tendencies, not a verdict on who you are.
