What does "killing He Ren" mean in the Book of Changes?

Ren is the ninth day. There are ten dry days. Ren represents the sun water in the north. There is another one, that is, the tenth in the sky, and decyl represents the yin water in the north.

Killing partial officials, also known as seven kills. Is to control the life of the Lord. Be masculine, be feminine when encountering Keta, and be an official. If you encounter others, you are right, that is, you are partial to the official (seven kills).

Good luck.
