Meaning of the Gyeongjin (庚辰) Ilju — Personality, Structure, and the 17th Pillar of the Sexagenary Cycle
The Gyeongjin (庚辰) Ilju is the 17th pillar of the sexagenary cycle. It represents the Heavenly Stem Gyeong (庚)—hard iron or raw ore (Yang Metal)—sitting upon the Earthly Branch Jin (辰), the dragon that harbors change. It is an extraordinary image: a massive piece of raw ore harboring a dragon, which, if refined, becomes a precious sword.

Personality and Temperament
The Gyeongjin Ilju is a competitive type with a grand scale and unconventional ideas. They prefer forging their own path over following the ordinary and thrive in high-stakes environments.
- Strengths: Extraordinary vision, boldness, and decisiveness in competitive situations.
- Points of Caution: Prone to being a “lone wolf.” Their extraordinary nature requires harmony with others to truly become a “precious sword.”
Structural Analysis — Myeongri Interpretation
The Gyeong (庚) Day Master sits upon the Jin (辰) Earthly Branch. Based on the main qi of the Ilji (daily branch), the Ten God is Pyeonin (偏印, Indirect Seal), and the 12 Stages of Life is Yang (養, Nourishment). The Indirect Seal is the star of intuition and specialized talent—unique ideas and expertise grow from the Ilji. The “Nourishment” stage indicates a structure of preparation, where one waits for the right time to cultivate strength.
In terms of Nabeum Five Elements, it belongs to Baellapgeum (白鑞金, Pewter Metal), a classification often used in traditional Myeongri to group pillars with the same Nabeum.
