Dear Tom,
I've received your email and I'm glad you will come to China. You said you were worried about getting along with new classmates? No worry about that. You are quite a lovely guy and they will like you.
But if you want to get along well wiyh your new classmates, you'd better introduce yourself actively and talk about their hobbies and any other things they have interests in, such as the life in USA and the differences between China and America. You can join their activities if possible. These are all good ways to live in.
Wish you to get well with the new life.
looking forward to your news sooner.
yours,
Lihua
