About Ziwei Doushu
Ziwei Doushu (紫微斗数), or Purple Star Astrology, is one of the most respected Chinese destiny systems, with origins tracing back to the Tang Dynasty. It constructs a chart of 12 palaces (命宫 Soul, 财帛 Wealth, 官禄 Career, etc.) and places over 100 stars, with 14 major stars (紫微 Ziwei the Emperor, 天机 Tianji, 太阳 Taiyang the Sun, 武曲 Wuqu, and others) being the most important. The Soul Palace (命宫) reveals your core personality and destiny. The Four Transformations (四化: 化禄 Lu fortune, 化权 Quan power, 化科 Ke fame, 化忌 Ji obstacle) show how your birth year's heavenly stem activates specific stars. The Five Elements Class (五行局) determines your decade cycles (大限). Unlike Bazi which focuses on stems and branches, Ziwei focuses on star placements in palaces.

The 12 palaces of Ziwei Doushu
A Ziwei chart divides life into 12 palaces (宮): Soul (命), Siblings (兄弟), Spouse (夫妻), Children (子女), Wealth (財帛), Health (疾厄), Travel (遷移), Friends (交友), Career (官祿), Property (田宅), Spirit (福德), and Parents (父母). Each is colored by the stars that fall within it.
The 14 major stars
At the heart of Ziwei are 14 major stars, led by Ziwei (紫微, the Purple Star). Each star has a character — Ziwei is imperial, Tian Ji strategic, Tan Lang magnetic. Their brightness in each palace (庙旺利陷) shows how strongly they express.
Classic patterns (格局) in your chart
Ziwei practitioners read combinations of stars as patterns (格局) — auspicious structures like Ji Xiang Li Ming (极向离明, lone Ziwei in the Soul Palace) or Zi Fu Chao Yuan (紫府朝垣, Ziwei and Tianfu supporting the chart). We auto-detect the major ones to give you a structured reading.
Frequently Asked Questions
What is Ziwei Doushu (Purple Star Astrology)?
Ziwei Doushu is a Chinese astrological system that uses your birth date, time, and gender to construct a chart with 12 life palaces and over 100 stars. The 14 major stars represent archetypal energies, and their placement in your palaces reveals your personality, career potential, relationships, and life path.
How is Ziwei Doushu different from Bazi (Four Pillars)?
Both are Chinese destiny systems but use different methods. Bazi analyzes the Heavenly Stems and Earthly Branches of your birth year/month/day/hour (the 'Four Pillars'). Ziwei Doushu places stars into 12 palaces and interprets their interactions. Many practitioners use both together — Bazi for the overall destiny framework and Ziwei for detailed life area analysis.
What is the Soul Palace (命宫)?
The Soul Palace (命宫) is the most important palace in your Ziwei chart. It is calculated from your birth month and time, and represents your core personality, innate talents, and primary life direction. The major stars in your Soul Palace define your fundamental character archetype.
Can Ziwei Doushu predict my future?
Ziwei Doushu maps the distribution of stars across twelve life palaces to describe tendencies in career, relationships, wealth, and health. It identifies favorable and challenging periods through timing cycles. Practitioners treat it as a decision-making framework based on elemental and stellar patterns, not as fixed prediction.
What are the 12 palaces in Ziwei Doushu?
