What's the difference between the Sun Constellation and the Rising Constellation?

The sun sign is the entity seen by others, and the rising sign is the shadow.

The Sun Constellation regards the earth as a point to determine the position of the sun on the ecliptic, while the Ascending Constellation regards the earth as an infinite number and looks at the position of the sun on the ecliptic from different points.

In astrology, only two stars will affect personality: one is the sun, the other is the moon, and the sun has influence: one is the sun sign, and the other is the rising sign.
