Yang Metal: The Sword

Geng (庚), the seventh of the ten Heavenly Stems.

The short answer

Geng (庚) is Yang Metal. Its classical image is raw ore, an axe or a sword: strong, decisive and direct. People born on a Geng day are traditionally read as courageous, loyal and justice-minded, the friend who tells you the truth and fights your corner.

The imageThe Sword

Iron straight from the mountain is rough and heavy. Put it in the forge, hammer it, quench it, and it becomes a blade: sharp, balanced and true.

That's Geng. It is the Day Master of courage and justice. It cuts through nonsense, protects what it loves and doesn't flinch from a hard conversation. And like a blade, it becomes truly great only after it has been through the fire.

StrengthsWhat Yang Metal brings

CourageGeng faces things head on. You'd rather deal with it now than let it fester.
LoyaltyA sword is sworn to someone. Geng defends its people fiercely.
DecisivenessAn axe cuts. Geng makes decisions and acts on them.
JusticeGeng has a strong sense of fairness and can't stand seeing the weak pushed around.

The shadowWhere Yang Metal gets stuck

Blades cut both ways. Geng's trap is bluntness that wounds, impatience, and a hunger for a fight even when none is needed. Unforged, Geng can be rough and aggressive. Its life lessons often come through pressure and hardship, which is exactly what refines it.

In loveYang Metal in relationships

In love, Geng is protective, loyal and straightforward, no games. It shows love by standing up for you. The growth edge is tenderness: not every disagreement is a battle to win, and a partner sometimes needs the sheath, not the sword.

At workYang Metal and career

Geng thrives with challenge and clear stakes: entrepreneurship, law, the military and emergency services, surgery, sport, turnaround projects, anywhere that needs someone to make the call. It struggles with slow bureaucracy and endless consensus.

BalanceWhat helps Yang Metal thrive

Classically, raw ore needs Yin Fire (丁, the forge flame) to become a fine blade: discipline, training and challenges that shape it. Water (壬) then cools and sharpens it: wisdom and expression after action. A sword left in the earth (too much Earth) rusts. Your full chart decides how much refining your Metal really needs.

How it connectsYang Metal and the five elements

In Ba Zi, every element feeds one element and controls another. From the point of view of a Yang Metal Day Master, here's what each element represents:

Same element · CompanionMetal: friends, siblings, peers, and rivals. Support, and competition.
Feeds you · ResourceEarth: learning, mentors, rest, the people and habits that nourish you.
You feed · OutputWater: your creativity, expression and what you give to the world.
You control · WealthWood: what you work on and earn from. Money, tasks, results.
Controls you · PowerFire: discipline, authority, rules and pressure. It shapes you, or wears you down.

Its natural partner among the ten stems is Yin Wood (乙 Yi). The two stems "combine," which is traditionally read as an attraction, though real compatibility always depends on both full charts.
