In recent years, WeChat is becoming more and more popular. It has made a big difference to our daily life.
We used to keep in touch with each other by writing letters or sending emails, but now more and more people are using WeChat. We can send voice and text messages through WeChat as well as pictures and videos easily. By using it, making friends is becoming easier. And we can share our life experiences faster. However, there are also some problems. Using WeChat too often is not good for students' study. And it is not safe for students to make friends by WeChat.
I think WeChat is helpful to us, but we should always be careful.
