How to turn off comments on qq?

Judging from your description, your QQ wants to turn off comments. I suggest you open QQ, enter the "QQ Panel", find and click the "QQ Space" button.

After entering the "QQ Space" page, click the "Settings" column in the upper right corner; After entering the "Settings" page, click "Leave a comment to prevent harassment" in the "Permission Settings" on the left; After clicking "Comment message anti-harassment", set "Comment reply" as "Only for yourself" in the pop-up window on the right to prohibit others from commenting on the conversation.
