The Four Pillars

庚︎Yang Metal — Gēng

Heavenly Stem · Yang Metal · the axe

The seventh Heavenly Stem — Yang Metal, the axe or raw ore, hard unrefined strength meant to cut and to build.

Gēng reads as decisive force: direct, principled, and willing to do the hard, clarifying thing others avoid. Its edge is most useful aimed at real work; turned carelessly on people, it wounds where it meant to help.
