Purple Star Astrology is a fortune-telling system that analyzes a person's birth chart or birthdate to tell them their future. This method is based on the concept of the twelve signs of the zodiac, and the four elements, as well as the idea of fate and the concept of the five elements. It is a form of fortune-telling that is very popular in China and Japan.

The system was developed in China during the Han Dynasty and has been used for over two thousand years. The fortune-telling process starts with the birth of a person, and the interpretation of their birth chart or fate. This is done by a special person, called a "fortune interpreter", who knows how to read the birth chart and determine the person's future.

The system is based on the concept of the five elements, which are fire, earth, air, water, and wood.
