Structural Reading — Myeongri Interpretation
The Gyeong (庚) Day Master sits on the In (寅) Branch. Based on the main qi of the daily branch, the 10 God is Pyeonjae (Indirect Wealth), and the 12 Stages of Life is Jeol (Extinction). Pyeonjae is the star of liquid assets—the sense for managing money and opportunities is embedded in the daily branch. Because it sits in the stage of “Extinction,” it is a dynamic structure characterized by repeated changes and comebacks.
In terms of Nabeum Ohaeng, it belongs to Songbaekmok (Pine and Cypress Wood), a classification frequently used in traditional Myeongri alongside other pillars sharing the same Nabeum.
