My favorite app is QQ. Because, now, it is the most common online communications software. With it, I can almost touch to every friend, no matter where they are. And QQ has powerful functions, which can meet various requirements of I. In addition to chat, it also contains other interesting such as functions space, tribes, bookstore, news, and so on.I think the most important thing is that the QQ friends get together, and we can at any time by group or discussion groups to chat. What’s more ,it is advancing with the times. For example, once a popular thing appearing , it'll be able to launch the corresponding service. 本文来源：https://www.wddqw.com/doc/b62a00c8650e52ea54189844.html
