Zi Wei, also known as Zi Wei Dou Shu, is a form of Chinese astrology that is sometimes referred to as the "Emperor's Astrology." It is a complex and intricate system that analyzes the positions of stars, planets, and other celestial bodies at the time of your birth. Unlike the more well-known Chinese zodiac, which is based on the 12-year cycle of animal signs, Zi Wei Dou Shu uses a detailed system of 12 palaces to interpret various aspects of a person's life, including career, relationships, health, and wealth.​
