Structural Analysis — Saju Interpretation
The Sin (辛) Day Master sits atop the Sa (巳) Earthly Branch. Based on the main Qi of the Ilji (Day Branch), the 10 God is Jeong-gwan (正官), and the 12 Stages of Life is Sa (死). Jeong-gwan is the star of honor and order—the foundation is a sense of dignity that seeks recognition within established norms. Because it sits in the ‘Sa’ (Death) stage, it is a structure of deep immersion, focusing on one path.
In terms of Nabeum (phonetic element), it belongs to Baek-rap-geum (白鑞金 / Pewter Metal), a classification often used in traditional Saju studies to group pillars sharing the same Nabeum.
