Why does the constellation change?

The renewal of the twelve constellations is due to the change of the earth's axis, the movement of the solar system and the movement of the stars themselves. The zodiac is synonymous with the orientation of the universe, and because the changes of the earth's axis, the movement of the solar system and the movement of the stars themselves are inaccurate, it is necessary to update the zodiac.
