Basic Properties of Yin Wood
Yin Wood (Yin Mu) is the third of the twelve Earthly Branches (Dizhi). Its element is Wood and its Yin-Yang polarity is Yang, representing the vigorous initial growth of Wood qi in spring. Yin month (Spring Begins ~ Awakening of Insects) marks the start of the year, when the ten thousand things begin to sprout. Hidden Stems (Cang Gan): Jia Wood (primary qi), Bing Fire (secondary qi), and Wu Earth (residual qi).
Etymological Imagery
The Shuowen Jiezi explains Yin as: "The kneecap. In the first month, Yang qi stirs, wanting to emerge from the Yellow Springs, yet Yin is still strong." The Hanshu states: "They extend and reach through in Yin." Yin means "to perform" — finally breaking through the soil. Having experienced the nurturing of Zi Water and the strength-storing of Chou Earth, the tender shoot pushes through the last layer of frozen earth and sees sunlight for the first time. This is the first "victory moment" of life force.
Yin is the "game-breaker" of the twelve Earthly Branches. Its power does not come from accumulation but from breakthrough — braving the cold, risking a late spring frost, it is the first to charge out. Therefore, Yin Wood individuals are naturally imbued with a "tiger spirit": daring to venture, daring to fight, unafraid of risk.
