How to delete something forwarded by others?

You can delete what you sent. If someone forwards it, the content of the conversation will not be displayed, but it will only prompt that the conversation has been deleted. The specific steps are as follows:

First, open the qq space and find the section to talk about.

Second, find my talk interface on the talk page and enter my talk.

Third, in the lower right corner of the specific talk, select Delete from the more drop-down menu to delete it.

Fourth, if you want to delete a comment, just select Delete under the comment.
