Heavenly Stem Geng (庚) — Yang Metal
Yin / Yang Yang
Element Metal (金)

The Geng day master is the seventh of the ten heavenly stems, representing Yang Metal. 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 Geng to raw ore, an unshaped sword, or a heavy axe — strong, blunt, and built for direct action rather than delicate work. Geng day masters are traditionally described as decisive, outspoken, and guided by a firm sense of fairness, often stepping in to settle disputes. This same directness is also traditionally read as bluntness or an unwillingness to compromise.

Traditional five-element theory holds that Geng Metal generally benefits from fire, said to forge raw ore into a useful tool, and from water, said to temper it and prevent brittleness. A large amount of wood cutting against it is traditionally read as dulling its edge over time rather than sharpening it. This forge-and-temper imagery is long-standing folk symbolism rather than a strict rule, and a complete reading always considers the chart as a whole.
