Mao is the fourth of the Twelve Earthly Branches, belonging to Yin Wood and corresponding to the Rabbit zodiac sign. The Mao hour spans from 05:00 to 07:00. As the Wood of mid-spring, Mao Wood internally stores Yi Wood; it is gentle, elegant, and luxuriant—symbolizing mildness, refinement, and artistic ability. Mao Wood is also a 'Peach Blossom' location, indicating strong interpersonal charm and innate artistic talent.
Mao Wood is identified from the Earthly Branches in the Four Pillars of a Bazi chart. If Mao appears in the Year Branch, the native belongs to the Rabbit zodiac; if Mao appears in the Day Branch, the Spouse Palace is occupied by Mao Wood. Mao Wood is strongest during Mao Month (the second lunar month).
A person born on a Ding-Mao day has Mao Wood in the Day Branch acting as the Indirect Seal; their spouse possesses artistic talent and a gentle disposition.
