Heavenly Stem Wu (戊) — Yang Earth
Yin / Yang Yang
Element Earth (土)

The Wu day master is the fifth of the ten heavenly stems, representing Yang Earth. As the day-pillar stem in a Four Pillars (BaZi) chart, it is traditionally treated as a marker of a person's underlying character.

Folk symbolism likens Wu to a mountain or a broad plateau — massive, immovable, and unaffected by passing weather. Wu day masters are traditionally described as reliable, patient, and generous with their time and resources, often serving as an anchor for people around them. This same solidity is also traditionally read as stubbornness or a resistance to sudden change.

Traditional five-element theory holds that Wu Earth generally benefits from a measure of wood, said to give it contour and purpose, and from fire, said to warm and enliven it. Excessive water is traditionally read as gradually eroding a mountain's firm footing rather than nourishing it. This shape-and-erosion imagery is long-standing folk symbolism, not a strict rule, and a full reading always considers the chart as a whole.
