Qq, send a message to a friend, and then delete the friend. Friend, can you receive it?

1. It can be received without message loss.

2. As long as you send it out, you will see it. If you send it out and delete it, but you can't see it yourself, the receiver has received it.

3. If you know the QQ password of the other party, you can log in to the other party's QQ before the other party has seen it, and then delete the information you just received so that the other party can't see it.

Note: after posting, you can't delete it. You'd better think about the content before posting.
