How to make the number of visitors who can't see my blog or talk about QQ space, and set the number of recent visits to be visible to themselves?

Hello. Make visitors visible only to themselves. Open a blog, and there is a "setting" next to the nearest visitor of the blog. Click to enter, and it can be set as "only you can see it".

Set who can comment. Click the gear key in the upper right corner of the space, space settings, permission settings, and comment reply. You can set who you want to comment on.
