Divination Systems (三式)
The three classical Chinese divination systems (三式). Six Ren (大六壬) derives a chart from the day pillar and hour branch via heaven/earth plate rotation and four-lesson extraction with nine transmission methods. Mystery Gates (奇門遁甲) arranges nine stars, eight doors, and eight deities on earth and heaven plates keyed to the current 局數. Polaris Astrology (紫微斗數) places 14 major stars across 12 palaces from lunar birth data with 四化 transformations.
