I do not think Wechat is going to affect the life of a student. First of all, we need to think carefully what is thefunction of Wechat.
As a communication software, Wechat can use internet connection to perform a voice message and SMS function. These function is provided by all the mobile phone already, with or without Wechat. The only advantage of Wechat is, it can save money. However, if a student can have amobile phone which can use Wechat, I believer this money saving is not so important to them.
This is the reason that I do not think Wechat is going to affect the life of a student, because what could affect a student's life is not Wechat itself, but the function of mobile phone.
Nowadays, WeChat has been a part of our life. It is becoming more and more popular with young people because of the following advantages. First, we can communicate with our friends by sending words and expressions very quickly. Second, we can share pictures, music and videos with them. Third, we can not only send voice messages to them but also speak to them directly. Besides, we can use it in any time. Last but not least, we use it for free and can save money. In my view, although WeChat has improved our lives, it should be used properly. We shouldn't lose ourselves in it.
