After Sina Weibo's private message is deleted, can the other party still see it?

1. After deleting a private message, you can only delete the content in your own private message, but the content in the other party's private message still exists, so the other party can still see the previous private message.

2. Weibo's chat messages, like QQ's, are stored in separate accounts, and it is impossible for one party to delete them.
