The Twelve Earthly Branches — Zi, Chou, Yin, Mao and so on to Hai — are the same as the twelve zodiac animals. If the Stems are surface energy, the Branches are the underlying ground of reality and the vessel that holds the flow of season and time.
Twelve Branches, animals and seasons
The twelve Branches match the twelve animals — Rat (子), Ox (丑), Tiger (寅), Rabbit (卯), Dragon (辰), Snake (巳), Horse (午), Goat (未), Monkey (申), Rooster (酉), Dog (戌), Pig (亥). Each also marks a season and hour, so Yin-Mao-Chen are spring and Si-Wu-Wei are summer, dividing the year.
The Branch of your birth month is especially important. It sets the season you were born into, and that season strongly shapes the whole chart’s strength and temperament.
Hidden Stems inside the Branches
A Branch is not a single simple energy; it holds several Stem energies inside it, called the Hidden Stems. On the surface it is one character, but within it two or three energies overlap.
This makes Branches more complex and grounded than Stems. Seeing which hidden energy a surface Stem is rooted in (Rooting) tells you whether that energy is mere talk or carries real strength.
Frequently asked
The animal is only the Branch of your birth year, so it shows only a broad direction. An accurate reading needs all four pillars, and the birth day (Day Master) and month carry far more weight.
When a Stem is rooted in a Branch’s Hidden Stem, that energy is considered to have real strength; without a root it only looks strong on the surface. That is why Hidden Stems are essential for judging strength.
