One: the other party only deletes you in one direction. (that is, directly delete you from his friend list. )

This statement can be seen. Lz can determine whether he deleted you in this way just by seeing if he is still in your friend list.

Two: blackening. It is deletion in two directions. He has also been deleted from your buddy list, and your buddy list cannot be displayed. You're not on his friends list either. You can't see this kind of signature.

I hope I can help you.
