Dear LiMing,
　　I know you are now having trouble communicating with others, and you may often feel lonely. That's because you are new here and people don't know about you. But I think you can make it if only you can follow the advice below.
　　First, you should take an active part in the discussions and show your own opinions about the matters, and at the same time, learn to listen to other people's views. Second, you should learn about your classmates' likes and dislikes. Then you can have much in common with them. This way, you can get to know more different people and show them that you are just as friendly. Last but not least, I'm always here ready to help. we can take part in some activities together and I can introduce you to others.
　　With time going on, people will know you better and will like to make friends with you if you can do as the above.
　　Best regards,
　　Zhang Hua
