What does the constellation mean?

Luck-probably refers to the luck you want to see at a certain moment.

Return of the Moon-The Moon Reflector is an astrolabe drawn every month when the Moon returns to its birth position. Look at the changes in mood and spirit every month.

The Return of the Sun-A chart of the sun's return to its birth position every year. Judge the overall luck in the coming year.

Split limit-a high precision deduction method. Push is simple and direct.

Solar arc-solar arc extrapolation method. It is the radian between the sun of the second forward point and the sun of the astrolabe. Every day the sun advances, it means that this person's life advances by one year. Solar arc push is to apply this radian to the astrolabe.

Fada-a common method in classical astrology. It is difficult to infer the fate of a precise point in time. The point is not what happened at a certain point in time, but a general trend.

These can be used to judge fortune. I hope my above answers can help you.
