Zi Wei Dou Shu — Purple Star Astrology
The "emperor of Chinese astrology": a twelve-palace chart ruled by the Purple Star.
Zi Wei Dou Shu casts your birth moment into twelve palaces — life, wealth, career, marriage and more — and places over a hundred stars among them, led by Zi Wei, the Purple Star of the celestial emperor.
Once reserved for the imperial court, it is now hugely popular in Taiwan and Hong Kong, prized for its uncanny specificity: not just what your fortune is, but in which decade, and through which palace, it arrives.
