Purple Star Astrology
Free Zi Wei Dou Shu Chart
Zi Wei Dou Shu (Purple Star Astrology) is often called the “king of Chinese fortune-telling systems.” Originating from the Song Dynasty, it maps over a hundred celestial bodies onto twelve life palaces to create a rich, multidimensional portrait of your destiny — covering personality, career, relationships, wealth, health, and more.
Our calculator generates a complete Zi Wei Dou Shu chart based on your Chinese lunar birth data. You will see all major and minor star placements, brightness levels, Four Transformations (Si Hua), and decadal fortune annotations — all rendered in the traditional 4x4 palace grid layout.
