How to check what others say without leaving a trace?

Look at people and say there are two ways to leave no trace.

The first method step: 1. When visiting other people's QQ space, if you want to delete your own browsing traces, you can first find "recent visitors" in your friend space and click enter;

2. Find your QQ avatar among the recent visitors among your friends, and click Delete on your QQ avatar to delete your browsing trace.

Second method step: 1. Enter my own space, find "Who have I seen" among my QQ space visitors, and click in; 2. Find your friend space browsing record, choose to delete or choose "its stealth access", and you can see what others said without leaving a trace.
