Structural Analysis — Myeong-ri Interpretation
The Gyeong (庚) Day Master sits on the Sul (戌) Branch. Based on the main Qi of the Ilji (daily branch), the 10 God is Pyeon-in (偏印), and the 12 Stages of Life is Soe (衰). Pyeon-in is the star of intuition and specialized talent—unique ideas and professional expertise grow from this daily branch. As it sits in the stage of ‘Decline’ (Soe), the structure favors building seasoned, internal substance over outward flashiness.
In terms of Nabeum Five Elements, it belongs to Cha-cheon-geum (釵釧金), a classification often used in traditional Myeong-ri alongside its paired pillars.
