How do you know if the constellation phase is good?

Generally speaking, hedging and 90 degrees are relatively bad phases.

3 points and 6 points are better phases.

For a single planet, it depends on whether the phase it participates in is good or not.

How does this stage affect this planet?

What is phase matching?

What is the strength of another planet?

Then we can give a comprehensive judgment on whether the phase is good or not.

This is the way you look at the astrolabe. Kung fu lies in whether you can make a correct summary from a lot of clues that are clueless or even contradictory.
