How do you explain the stars in metaphysics (do you really mean the stars in the sky)?

Of course, the official in charge of astronomy actually observed it, but the name is different from now.

The five ancient planets (water, fire and earth in Jin Mu) are not the five planets now. For example, Mercury refers to the "camp room" among stars, and Mars refers to the "fire" of stars.

There are also some nouns that are not the real name of a star, but its position, such as guest star, which refers to a star entering a certain star field and is common in astrology.
