Why are the twelve constellations updated?

The zodiac is synonymous with the orientation of the universe, and because the change of the earth's axis, the movement of the solar system and the movement of the stars themselves are not accurate, the zodiac will be updated.

In astrology, the zodiac is synonymous with the orientation of the universe. The zodiac represents 65,438+02 basic personality archetypes.
