WeChat is becoming increasing popular with people. Recently I have made a survey among my classmate about the use of WeChat. According to a result, 45% of the classmates admit they often use it because comparing with other means of communication, WeChat has more advantages. It was cheap, convenient and easy to send all kinds of messages around. Besides, 35% of whom are against using it, saying it will affect their study. Not using WeChat, the rest has no opinion about it. As far as I'm concerned, since WeChat offers us great convenience, it should be made good use. We should not be slaves to it or let it to govern our minds and behaviour.
