What is a rising constellation and what is a sinking constellation?

The rising constellation is the rising constellation on the eastern horizon when you were born, that is, the constellation where the first palace head (Asc) is located, and the sinking constellation, er, should be called the descending constellation, that is, the constellation that was descending on the western horizon when you were born, just opposite to the rising constellation, that is, the constellation where the seventh palace head (Des) is located.

If Capricorn rises, it must be Cancer, because Capricorn and Cancer are just corresponding constellations.
