Wechat friends circle sent a talk about how others look at comments.

Comments from WeChat friends circle can only be seen by common friends. And only friends can see each other's comments.

For example: a, b, c.

A and B are WeChat friends, B and C are WeChat friends, and A and C don't know each other.

B can see the public comments of A and C, but other friends of A and C can't see the comments that B doesn't know.

A and C are not good friends, so naturally they can't see each other's circle of friends.

So if B wants to see all the comments of A or C, he can only know all their friends.
