The Kui Gang pattern is primarily determined by the Day Pillar. In traditional Bazi, four Day Pillars are recognized as Kui Gang: Geng Chen, Geng Xu, Ren Chen, and Wu Xu. If your Day Pillar falls into one of these four, you meet the basic condition for a Kui Gang pattern. The Earthly Branches Chen and Xu are considered positions of 'Heavenly Net and Earthly Net'—associated with sternness and storage—so they become the root of Kui Gang. In Bazi theory, the pattern is considered stronger when the Kui Gang appears in duplicate or multiple times. If the same Kui Gang Stem-Branch pair shows up repeatedly in your chart, the energy is often more intense. However, whether the pattern truly forms depends on the overall balance of the Five Elements and their likes/dislikes in the full natal chart—it’s not just about the Day Pillar. This is why a comprehensive reading is essential.

Traditional Bazi describes people with a Kui Gang pattern as intelligent, decisive, quick to act, and naturally radiating a quiet authority. They tend to have strong opinions and initiative, showing exceptional courage and resilience when facing challenges—rarely giving up easily. In relationships and work, Kui Gang individuals often draw clear lines between right and wrong, value principles, and therefore naturally show leadership in groups. However, the flip side of this strength can be stubbornness and inflexibility, so they need to be mindful of communication flexibility. It's worth noting that traditional astrology suggests slight differences between male and female Kui Gang personalities, but these are cultural references. Actual character is still shaped by upbringing, education, and personal effort—don't generalize.

In traditional destiny studies, Kui Gang is classified as one of the 'noble patterns,' meaning that if the configuration is pure and the chart supports it, the person can achieve career success—especially in fields requiring decisiveness and authority, such as management, law enforcement, military, or entrepreneurship. Ancient texts suggest that Kui Gang individuals experience dramatic ups and downs—soaring in favorable times and tested by adversity in difficult periods. The classics also warn against 'punishment and clashing' for Kui Gang: if your Major Luck Cycles or Annual Luck clash with Chen or Xu, the fluctuations may be more pronounced. Overall, Kui Gang is seen as a pattern that blends strength with nobility, but whether the fortune is good or bad depends on many interacting factors.
