Reading the Structure — Saju Interpretation
The Sin (辛) Day Master sits upon the Mi (未) Branch. Based on the main Qi of the branch, the 10 Gods correspond to Pyeonin (Indirect Resource), and the 12 Stages of Life correspond to Soe (Decline/Maturity). Pyeonin is the star of intuition and specialized talent—unique ideas and expertise grow from this pillar. As it sits in the stage of Soe, it is a structure that prioritizes seasoned substance over outward flashiness.
In terms of Nabeum, it belongs to Nobangto (Roadside Earth), a classification frequently used in traditional Saju studies to group pillars sharing the same phonetic element.
