Geng Metal Day Master — the axe, the sword, raw ore
The blade — decisive, loyal to what is right, and forged under pressure.
Geng (庚) is yang Metal — raw ore, the axe, the broadsword: the cutting edge before the polishing cloth. In classical imagery Geng is the star of justice and execution; the tradition says it is the metal that does not flinch, and Day Masters who carry it rarely do either. If Geng is you, you instinctively see what is wrong — in the plan, the story, the situation — and feel personally responsible for chopping it free of what is right. This is why Geng people win arguments and occasionally lose rooms: the axe was built for tasks, not for tendons, and it has never once heard of hedging for politeness. The classics add the crucial condition: Geng Metal wants Fire — an axe is only an axe after the forge, and the raw ore is famous for being unyielding right up until it becomes sharp.

Geng Metal strengths
- Decisiveness — you end ambiguity; a Geng decision lands with the sound of the axe, and people rest easier after it.
- Courage — you will say the true thing in the room full of careful people, and do the hard thing no one else volunteers for.
- Integrity of edge — Geng keeps commitments like blade angles: precisely, or not at all.
What to watch
- The cut that lingers — true and delivered-at-full-force are not the same sentence; the blade is sharp even when you aim it at people you love.
- Impatience — ore has no patience for slow chemistry; other people's processes are not their disqualifications.
- Never sheathing — a sword that is never put away bends on its own edge eventually.
Career and money
Geng charts are made for high-stakes decisiveness: the military and uniformed services, law, surgery and emergency medicine, engineering, professional athletics, trading floors, startups in wartime. The classic warning — ore needs Fire — is also career advice: Geng performs best with a forge around it, a mission hot enough to shape the edge.
Love and relationships
In love Geng protects — fiercely, concretely, in acts: the fence fixed, the argument ended, the plan that survives. Romance asks the axe for something the forge gives Metal: heat without impact. A good partner for Geng says "that hurt" plainly — because you mean no harm and would genuinely never guess — and gives you something worth defending.
Growing the blade
Classically, Geng is forged by Fire (Bing, Ding) — challenge and passion that turn raw ore into a tool — and tempered by Water (Ren, Gui), which washes the slag and lets sharpness flow as strategy instead of splatter. Yi Wood, its classical pairing, is the vine that teaches the axe what is worth cutting.
Day Master pairings
Geng's classical partner is Yi Wood (乙庚合, "Metal-Wood combine") — the blade and the vine. Fire refines, Water sharpens. Pairings are chart-wide reading; Day Pillars head the article, they don't end it.
