What does WeChat mean by showing the other party's rejection information?

Display the rejection message, indicating that the other party has blacklisted you (as shown below). If it is deleted, the prompt you display is "You are not the other person's friend".

In this case, only the other party can blacklist you, and then you can send a message, and the other party can receive your message normally, or you can blacklist the other party. The specific operation steps are as follows:

Wechat version: 8.0.32

Operating a mobile phone: Glory 9X

1, open WeChat, click the address book below, and find the friends to be blacked out;

2. Jump to your friend's profile page and click on the three black dots in the upper right corner;

3. Click the gray button to join the blacklist;

4. A page will pop up after clicking, and click OK.

In this way, the other party successfully blacklisted.

You don't have to add friends if you move out of the blacklist.
