Send a text message saying that someone else has made you a friend.

If you use WeChat to send a message to the other party, but there is an exclamation mark in front of the display and it is red, it means that you are not the other party's WeChat friend. If you used to be a WeChat friend, it means that you deleted the other party, or the other party deleted you, and of course it may have been deleted by mistake.

At this time, if you want to send a message to the other party successfully, you must re-add the other party's friends and ask the other party to agree.

If you don't receive a prompt after sending the verification code, the other party didn't see your request. Or saw it and ignored your request. Of course, I may not want to be your friend.

If you are an acquaintance, just call and say yes. But if you are a stranger, you must wait until the other person passes.
