What is Zi Wei Dou Shu?
Zi Wei Dou Shu (Purple Star Astrology) is a traditional Chinese destiny system that lays out a twelve-palace chart from the birth date and time, reading personality and fortune through star distribution. It belongs to traditional cultural study, and results are for entertainment only.
What information do I need to chart my chart?
You need your birth date (solar or lunar), birth time (as precise as possible), and birthplace. The more accurate the time, the more reliable the Ming Palace.
Is Zi Wei Dou Shu charting free?
Yes. Ziwei AI offers completely free charting and basic readings; registered users can unlock AI-powered deep interpretation and more.
What is the Ming Palace?
The Ming (Life) Palace is the starting point of the twelve palaces. It represents your personality baseline and life direction, and is the first station of any chart reading. Its position is fixed by the birth month and hour, so an accurate birth time keeps this starting point reliable.
What are the fourteen major stars?
They include the Big Dipper group — Zi Wei, Tian Ji, Tai Yang, Wu Qu, Tian Tong, Lian Zhen — and the Southern Dipper group — Tian Fu, Tai Yin, Tan Lang, Ju Men, Tian Xiang, Tian Liang, Qi Sha, Po Jun.
What do the Four Transformations mean?
The Four Transformations are Hua Lu, Hua Quan, Hua Ke, and Hua Ji — four markers of star energy flow indicating the direction of a star's energy in a specific chart. Hua Lu adds resource and ease, Hua Quan adds command, Hua Ke adds refinement and reputation, and Hua Ji marks where energy is tense or requires adjustment.
What is the difference between decadal and annual limits?
Decadal limits divide life into ten-year stages, while annual limits observe a single year's fortune. Together they form the basic framework of fortune analysis. A decadal limit sets the ten-year theme, and the annual limit layers the current year's detail on top of it.
What is the difference between Zi Wei Dou Shu and BaZi?
BaZi focuses on the interplay of heavenly stems and earthly branches, while Zi Wei Dou Shu focuses on star-palace combinations. Both are traditional destiny systems with different methods.
Can two people's charts be read together?
Yes. Ziwei AI offers a couples compatibility feature that compares the key palaces of two charts to observe personality complementarity and relationship dynamics. Results are for entertainment only.
Should I take chart readings at face value?
No. Chart readings belong to traditional cultural study and entertainment. They must not replace medical, legal, or investment advice. Please treat them rationally.
