What happened when the WeChat circle of friends received a text message from a friend but couldn't see a reply?

The first type: when you reply to a friend's comment, you click on the comment given by your friend, and you will see the preset in the input box: reply to so-and-so. Only the two of you can see the content of this reply, and no one else can see it.

The second type: when replying to friends' comments, directly comment on what you posted. Note that the preset in the input box at this time is: Comment. In this way, everyone can see your reply, and everyone who comments on you will receive your comments.
