Dear marry,
After reading your letter,I know that you worry about your life here at school.
Don't worry,Marry.It's common that when you com to a new country,you will be faced with a lot of challenges like language learning.I should say,we students here are really nice and helpful.Besides,you can ask your teachers for help when you meet with problems.They love their students,even those from abroad.
In my opinion,you should learn to be brave and try to communicate with your classmates.The closer you stay with them,the more they will understand you.your confidence will grow as you get to know them,and you'll certain find that you have many friends.
have a good time in China!
Yours,
Li Hua
