The Gichuk (己丑) Ilju is the 26th pillar of the sexagenary cycle (六十甲子). It represents the Heavenly Stem Gi (己), the Yin Earth that nurtures all things, sitting upon the Earthly Branch Chuk (丑), the Ox, which symbolizes silent endurance. It is the image of a snow-covered field in midwinter—gathering strength while waiting for spring.

Personality and Temperament
The Gichuk Ilju is the “farmer type”—diligent and deeply reliable. While far from flashy, their accumulated inner strength shines brighter as time passes.
- Strengths: Steadfast diligence, profound reliability, and unwavering consistency.
- Points of Caution: Excessive caution can lead to hesitation even when opportunities arise. Sometimes, you must be the one to take the first step into the snow.
Structural Analysis — Myeongri Interpretation
The Gi (己) Day Master sits upon the Chuk (丑) Branch. Based on the primary energy of the Day Branch, the 10 Gods correspond to the Peer (比肩), and the 12 Stages of Life correspond to the Grave (墓). The Peer is the star of the self and subjectivity—the power to stand on one’s own is supported by the Day Branch. The Grave position indicates a structure of management, gathering, and preservation.
In terms of Nabeum, it belongs to Byeokryeok-hwa (Thunderbolt Fire), a classification often used in traditional Myeongri to group pillars sharing the same Nabeum.
