Yi Hai · 乙亥
Yi Hai pairs a Yin Wood Day Master with 亥 (the Pig), a Water branch. If this is your day pillar, the pairing below describes tendencies worth observing — not a verdict.
The Day Master on top
Yin Wood · 乙 — The classical image for 乙 is a vine or climbing grass: growth that finds a way around, through, and along whatever exists. A Yin Wood Day Master tends to advance by adapting — reading the terrain and adjusting the route, without giving up the destination.

In a day pillar, the branch is read as the spouse palace: the texture of close partnership. 亥 (the Pig) carries these hidden stems, each read as a relationship between that stem and your Day Master:
壬
Direct Resource
Direct resource — care, credentials, protection, and knowledge that steadies the self.
甲
Rival Wealth
Opposite polarity, same element — close competition, shared resources, sharp give-and-take.
Na Yin
The Na Yin of Yi Hai is 山头火 — "Mountaintop Fire". 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 乙亥 treat 申酉 as "void" — branches whose signals are read as weakened or delayed rather than absent.
Is Yi Hai 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.
