But as the “White Collar Diary” group shows, as a guy, I’m not allowed to post in it, no matter what my job is: The college group “Campus Diary,” which has been viewed by more than 14 million people within 24 hours of its launch, also allows only female users to post.

All of Alipay’s 400 million users can join “Circles” groups, which include one for college students, another for white collar workers, and a third for Chinese citizens living overseas.The “tip” function is basically a “like” button with cash attached.
