First released on Jan. 21, 2011, WeChat is very popular for students and its user have reached up to 300 million at present. It is aimed at promote instant communication among people with voice messaging, text messaging, photo sharing, etc. Beside, it provides a chance for the users to share their wonderful stories in the life and make many new friends. Personal, I think WeChat make life easier because we can save money used the Internet-based application and the multimedia communication enables us to share more with our friends. However, we should spend too much time on it, that may bring negative effects on our life and study if we become WeChat-addicted.
