Wood is the first of the Five Elements in BaZi — the element of spring, of new beginnings, of upward growth. It's the element of the visionary, the pioneer, and the strategist who plants seeds today for harvests they may not live to see.
If you have a Wood Day Master (Jia or Yi), Wood is your core nature. But even if you don't, Wood appearing in other pillars of your chart shapes your personality, relationships, and life experiences in meaningful ways.
The Nature of Wood
Wood's fundamental drive is growth — upward, expansive, always reaching for light. This manifests in Wood-influenced people as a strong orientation toward the future: they're never quite satisfied with the present because they can always see further.
Wood corresponds to: - Season: Spring - Direction: East - Organs: Liver, gallbladder - Color: Green - Taste: Sour
Yang Wood (Jia) vs. Yin Wood (Yi)
Yang Wood (甲): The great tree — upright, principled, and immovable. Jia Wood people are long-term strategists who build lasting things. They're less flexible but more reliable.
Yin Wood (乙): The vine, the flower, the grass — adaptive, charming, and resourceful. Yi Wood people find paths around obstacles and leverage relationships skillfully. They're more flexible but can struggle with taking firm stances.
Wood's Relationships With Other Elements
Water produces Wood (favorable): Water nourishes Wood. For Wood Day Masters, Water in the chart represents support, resources, and learning. Strong Water in a Wood chart usually indicates intelligence, access to mentorship, and good fortune in education.
Wood produces Fire (Wood's Output): Wood feeds Fire. For Wood Day Masters, Fire represents their creativity, expression, and productivity. Strong Fire output suggests a creative, expressive person who generates value naturally.
Earth is Wood's Wealth: Wood controls Earth. Earth represents financial resources and material wealth for Wood Day Masters. Favorable Earth placement correlates with wealth accumulation potential.
Metal controls Wood (potentially challenging): Metal cuts Wood — the axe to the tree. Strong Metal in a Wood Day Master's chart represents discipline and structure, which can either refine Wood or suppress it, depending on the chart's balance.
Wood clashes with Metal when Metal is excessive without proper support.
Wood Health Connections
In Chinese medicine, Wood governs the liver and gallbladder. Wood-heavy charts or Wood Day Masters under stress can be susceptible to liver-related conditions, eye issues, and tendons/ligaments. Anger (Wood's associated emotion) that's suppressed tends to manifest physically for Wood types.
Wood in 2026
