QQ has a friend space, which seems to be accessible only by updating the content. For example, the content is updated, the space can be accessed, and it will become an application in a few days.

I'm sure she's changing her permissions herself. QQ space can set permissions, but there is no setting like her. Your friend may have a psychology that she has updated the content, and she wants everyone to know that she has updated the content, so it is ok to know her recent situation. I once had the experience that as long as there is new content, I will open my space. When you are in a bad mood, set permissions again. Normal situation.
