Basic Properties of Xu Earth
Xu Earth (Xu Tu) is the eleventh of the twelve Earthly Branches (Dizhi). Its element is Earth and its Yin-Yang polarity is Yang, making it dry-hot Earth. Xu month (Cold Dew ~ Winter Begins) is late autumn when Earth flourishes and Fire qi enters storage. Xu is the Fire Storage (Mu Ku), with Hidden Stems (Cang Gan): Wu Earth (primary qi), Xin Metal (secondary qi), and Ding Fire (residual qi).
Etymological Imagery
The Shuowen Jiezi explains Xu as: "To extinguish. In the ninth month, Yang qi is faint; the ten thousand things are fully completed; Yang descends into the earth." The Hanshu states: "They all enter in Xu." Xu means "to extinguish" — the splendor has drawn to a close, the ten thousand things wither. Grass and trees turn yellow, fallen leaves return to their roots; the lush greenery that once covered the mountains has all gone back into the earth. Xu's imagery is the dusk of late autumn: the setting sun like blood, the vast earth stretching into the dim distance, all the bustle now over.
Yet Xu is not desolate — it uses a fire (Xu is the Fire Storage) to burn dead branches and withered leaves to ashes, turning them into next year's fertilizer. Hence, Xu Earth individuals carry a fundamental quality of "duty fulfilled to the end": they protect, wrap up, and clean up, ensuring that every matter receives a dignified conclusion.
