Geng Zi · 庚子
Geng Zi pairs a Yang Metal Day Master with 子 (the Rat), a Water branch. If this is your day pillar, the pairing below describes tendencies worth observing — not a verdict.

Sharp output — wit, critique, and originality that can cut as well as create.
Na Yin
The Na Yin of Geng Zi is 壁上土 — "Plaster-Wall Earth". 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
Dormant — Quiet / dormant — the Day Master’s force is largely offline in this spot.
Void branches (Xun Kong)
Charts anchored on 庚子 treat 辰巳 as "void" — branches whose signals are read as weakened or delayed rather than absent.
Is Geng Zi 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.
