Why do WeChat plus friends send verification messages?

In fact, I believe that many people will encounter this situation. This situation is that it is in his address book, but it is not in his address book. When he adds WeChat, he will display "friend's verification message"; This is the verification message of the settings, just like QQ.

It is convenient to read the verification message. Acquaintances know it at a glance, and directly agree that it needs to be verified when setting privacy and adding my friends. As soon as this is opened, this will happen. With a drift bottle, this will happen to people nearby.

The first situation is that you were friends before, and then you deleted each other. The other party directly added it back. The source of this situation is the "friend verification message". The second situation is that the other party adds you as a friend from the "drift bottle" and "people nearby", and this prompt will also appear.

The method of opening friend verification by WeChat: First, open WeChat, click My, select Settings, select Privacy, and then open the verification option when adding me as a friend. At this point, click "Add Me" below to open and add you as a friend through micro-signal, mobile phone number and QQ number.
