What is Zi Wei Dou Shu?

Zi Wei Dou Shu assigns symbolic stars to twelve rooms from the birth date and time. Each room represents an area of life. A star is read through the room it occupies and its connections with other areas, rather than through its name alone.

The twelve rooms include themes such as self, love and partnership, work, money and family. Considering which stars occupy which rooms offers a perspective on your strengths and what you may want to value in life.

Classical sources including Zi Wei Dou Shu Quan Shu are consulted, with their ideas adapted to contemporary life rather than applied word for word. The specialist version distinguishes natal rooms from the areas emphasized each year and shows the calendar and star-assignment tables used.
