What are the three lucky stars mentioned in Kong Xuan Feng Shui?

In the mysterious geomantic omen, the good and bad stars are divided according to Yuan Yun.

When the stars are transported, for example, it is the eighth national day, then eight white stars are transported, and then there is wealth and good luck. At the next National Games, that is, the ninth National Games, nine purple is a lucky star, so it is also an angry star, and a white star at the first National Games is also a prosperous star in the future, so it is also a lucky star. This is one of the main bases of mysterious geomantic omen.

Correspondingly, the seventh movement is Qi retreating the stars, while others, such as the third, fourth and fifth movements, are evil stars and death stars.
