Chuk (丑) is the frozen ground of deep winter, a place of patience preparing for spring from within. It embodies an energy that moves slowly and steadily, like an ox chewing its cud, never ceasing in its progress.

Personality Traits

Those with a strong Chuk (Earth) influence are typically reticent and sincere; once they begin a task, they pursue it with steadfast perseverance. They possess great resilience in enduring hardship and are adept at saving and accumulating resources. However, because they tend to keep things bottled up inside, they can be formidable if they ever reach a breaking point.

San-hap and Clash

It forms a Metal Bureau (金局) through the San-hap of Sa-Yu-Chuk (巳酉丑), and it experiences the Chuk-Mi Clash (丑未沖) with Mi (未)—a collision between two Earth elements that reveals the hidden treasures (hidden stems) within.

Frequently Asked Questions

Q. Is it true that people born in the month of Chuk (December–January) are destined for hardship?

A. Because Chuk is a character that “waits for spring in frozen ground,” patience in one’s early years often appears in their life narrative, but hardship is not predetermined. Rather, thanks to the power of accumulation, they are often seen as a type that achieves solid results from middle age onward.


In Saju, Earthly Branches represent ‘time and environment.’ The manifestation of the same character varies depending on whether it is located in the Year, Month, Day, or Hour pillar, and what kind of combinations or clashes it forms with surrounding characters.
