Geng 庚: Yang Metal, the blade and the ore

A name you can say out loud: what the Geng image describes, where it sits among the five elements, and how it compares with the other nine stems. Nothing to fill in.

At a glance. Geng (庚) is the Yang Metal stem, one of ten possible Day Masters. A Day Master is the stem of the day pillar, the reference point for describing a BaZi chart. The image describes tendencies, not outcomes, and it is not a reading of you. Last update: 2026-11-14.

What the Geng image describes

Geng is pictured as raw metal or an axe: direct, strongest when tempered. Teachers use the image so the stem is easy to remember. People use it to talk about tendencies such as:

  • Clear edges: saying what it means.
  • Deciding, then cutting away the options it did not choose.
  • Getting stronger through pressure and heat, the way ore becomes steel.

The stretch in the image: being tempered. The image needs the forge as much as the edge.

These are tendencies the image is used to talk about. They are not a description of you, and they do not predict anything. A full chart has eight characters; the Day Master is one of them.

Solid: feeding cycle (生). Dashed: shaping cycle (克). Outlined: Metal.

  • Same element · Companions 比劫

    Other Metal stems sit beside Geng as peers. In chart vocabulary this group is called Companions (比劫): people and pressures that are like you. It names a relationship, not a rival or a friend.

  • What it feeds · Output 食伤

    Metal feeds Water (金生水). In chart vocabulary, what the Day Master feeds is its Output (食伤): expression, making, saying. It describes a direction of energy, not talent or luck.

  • What it shapes · Wealth 财

    Metal shapes Wood (金克木). In chart vocabulary, what the Day Master shapes is called Wealth (财): what it works on and manages. Despite the name, it is not a money forecast.

  • What shapes it · Officer 官杀

    Fire shapes Metal (火克金). In chart vocabulary, what shapes the Day Master is called Officer (官杀): rules, deadlines, responsibility. It describes structure, not punishment.

  • What feeds it · Resource 印

    Earth feeds Metal (土生金). In chart vocabulary, what feeds the Day Master is called Resource (印): learning, support, rest. It is a kind of input, not a guarantee of help.
