Meaning of the Gyeong (庚) Heavenly Stem — Complete Guide to Yang (陽) Metal (金) Day Master Personality

Gyeong (庚) is cast iron before refinement and raw ore in a rocky mountain. It represents the cool, cutting energy of autumn known as suksaljigi (肅殺之氣) — the force that clears away what has not matured and leaves only the fruit.

Personality and Temperament

A Gyeong metal day master is straightforward, quick to decide, and values loyalty. This stem has the temperament of a reformer who overturns what is wrong, handling matters by principle without taking sides. It is often described as a character with the spirit of a soldier or swordsman.

  • Strengths: Drive, decisiveness, and loyalty. The ability to cut through a crisis like a blade.
  • Points to watch: Unrefined metal is rough. Excessive bluntness can create enemies, flexibility may be lacking, and once a relationship turns sour, it may be cut off in a single stroke.

Suitable Fields

Fields that require decisive action and firm resolve, such as the military, police, prosecution, sports, surgery, engineering, and restructuring.

Relationships with Other Characters

When Gyeong meets Jeong fire (the furnace), it is reborn as a fine sword — the greatest growth narrative for Gyeong metal. With Eul wood, the Eul-Gyeong combination creates harmony between softness and strength.

Frequently Asked Questions

Q. I am Gyeong metal, but I am indecisive. Why is that?

A. Gyeong metal’s decisiveness is a story that comes “after refinement.” If fire (火) energy is weak and the person remains in a raw-ore state, a strong nature may hesitate because it has not yet found direction. As discipline, experience, hardship, and training accumulate, the original decisiveness awakens over time.


The day stem (日干) is the center of a saju chart, but it is not the whole chart. Even the same day stem can manifest very differently depending on the composition of the other seven characters. Myeongli should be used as a language for self-understanding.
