What is the seal of Jiao Ren in Changyi?

The lasting Jiao Ren Seal is a blue rune on the ear. The significance of Jiao Ren's seal is to confirm that the other person is his life partner. The long-term intention is that the blue rune left on Ji Yunhe's ear is his Jiao Ren seal, and this Jiao Ren seal can connect two people's five senses and feel each other's pain and danger.

The mark that Changyi left on Ji Yunhe's ear actually told her to protect her for life, but Ji Yunhe didn't know the meaning of this mark at that time, thinking that Changyi wanted to control himself.

In Ji Yunhe's view, Jiao Ren's seal may be a constraint, but for Jiao Ren, it is a symbol of a pair of lifelong partners. Long Yi is very concerned about Ji Yunhe. He knew that Ji Yunhe's body couldn't stand the ordeal, so he planted Jiao Ren's mark to heal her in the name of imprisonment, but Ji Yunhe didn't know all this.

Jiao Ren Seal seems to be Changyi's control over Ji Yunhe, but it is actually a protection for her. In order to protect Ji Yunhe, Changyi will not let Ji Yunhe leave anyway.
