Ancient strategic divination
Zhuge Liang from "Romance of the Three Kingdoms" was known as a master of Qimen Dunjia. Summoning the southeastern wind at the Battle of Red Cliffs and confusing enemies with the Eight Trigrams Formation were all attributed to Qimen Dunjia techniques. Qimen Dunjia is not mere fortune-telling. It is a strategic discipline that comprehensively analyzes astronomy, geography, and human affairs to find optimal timing and direction. It is the emperor's study that reveals when to advance, when to retreat, and which directions are auspicious or inauspicious.
