What is Qi Men Dun Jia?
Qi Men Dun Jia (奇门遁甲) is an ancient Chinese divination system that arranges the Eight Doors (八门), Nine Stars (九星), Eight Spirits (八神), and Heaven/Earth stems into a 9-palace grid for a specific moment in time.
While Bazi reads the destiny encoded in your birth moment, QMDJ reads the energy landscape of a specific hour, day, or month — making it the classic tool for choosing timing (择时) and direction (择方).
Each of the nine palaces combines a door, a star, and a spirit to reveal which actions are favored in that window. The 值符 (Chief Star) and 值使 (Chief Door) anchor the reading.
Qi Men Dun Jia vs Bazi
Bazi answers "who you are" — your talents, cycles, and life tendencies from the birth chart. QMDJ answers "when to act" — the best moment and direction for a specific decision.
Used together, Bazi shows the potential and QMDJ pinpoints the timing. This combined reading is something single-tool competitors cannot offer.
