Speaking of Xiaonei, whether high school students or college students are quite familiar with it, right? But recently, when I heard that "Xiaonei" would be renamed as "Renren", I couldn't bear it mentally. Judging from the name "Xiaonei", I think it was originally intended to build a bridge for schoolmates who were separated by going to college or working. However, now it's said to be renamed as "Renren", and I feel that the taste has changed a bit. Then, what's the difference between it and those "Kaixin" and "Huanlewo"?
