Zi Wei Dou Shu: Purple Star Astrology for Beginners

If BaZi is the weather map of your elements, Zi Wei Dou Shu (紫微斗数) is the castle diagram: your life arranged into twelve palaces around a courtyard, each garrisoned by symbolic stars. Attributed to the Daoist sage Chen Tuan of the Five Dynasties era, it is the second great pillar of Chinese fate calculation.

The twelve palaces

The chart is a square of twelve sectors named by earthly branch, each governing a domain: the Self palace (temperament), Siblings, Spouse, Children, Wealth, Health, Travel, Friends, Career, Property, Fortune (inner life) and Parents. To read a domain, look at the stars garrisoning its palace.

The stars

Fourteen major stars form the backbone — the emperor star Zi Wei, the strategist Tian Ji, the sun and moon Tai Yang and Tai Yin, the warrior Wu Qu, the benefactor Tian Tong, and so on — joined by minor stars of speed, charm or noise. Each star brightens or dims by palace (its "brightness" grade), and four stars can carry a transformation: Lu (flourish), Quan (power), Ke (fame), Ji (obstruction).

Your first reading

Start with three palaces: the Self palace describes your operating style; the Career palace shows how you build; the Spouse palace sketches partnership. Notice which major stars sit there and whether any carry a transformation — Ji on a Career star says the work path has friction to manage, Lu on a Wealth star says resources flow when you show up.

How to read the palaces

Self palaces vs. other palaces. Life, Wealth, Career, Property, Fortune and Health are 'self palaces' — they speak to your own pattern, money, work, home, spirit and body. Siblings, Spouse, Children, Travel, Friends and Parents are 'other palaces' — they speak to the six relations. An auspicious star in a self palace benefits you directly; in an other palace it often shows up through a relative.

The trine and opposition (三方四正). No palace is read alone: take it with its trine (the other two palaces in its earthly-branch group — 申子辰 / 寅午戌 / 巳酉丑 / 亥卯未) and its opposition (the clashing branch). If the Life Palace sits at 子, its trine is 申 and 辰 and its opposition 午 — the four together form the full picture.

Four things per palace: ① the major star sets the frame (exalted or fallen); ② auspicious and malefic minor stars raise or lower it; ③ the four transformations (Lu, Quan, Ke, Ji) show which way it moves; ④ the trine and opposition meet or break it.

Soul & Body stars

Once the Life Palace is fixed, two stars govern the self: the Soul star (命主) is set by the Life Palace's branch; the Body star (身主) by the birth-year branch. The table follows the Complete Book's rule:

From the classics

「学问之难，莫难于星命之学；而星命之学，莫难于紫微斗数。」"Of all learning, none is harder than the study of fate by the stars; and among star-fate studies, none is harder than Zi Wei Dou Shu." — Tai Wei Fu, in the Zi Wei Dou Shu Quan Shu, the tradition's foundational compilation.—— 《紫微斗数全书·太微赋》（题宋·陈抟撰，明·罗洪先辑）
