Is there any way to send QQ space? Tell me about the time before the show.

There is no way to modify the date after the QQ space talk is released. You can modify and edit the previously deleted or useless conversation, replace it with what you want to publish, and then delete the conversation whose date you want to change.

How to edit and modify the published talk content again: enter the talk space, move the mouse to the "More" button behind the talk content, click "Edit" to modify the content or permissions, and finally publish it again.
