Dear Li Hua,

    It has been two months since I came to Shanghai for study. However, I feel unhappy. First, I'm afraid to speak to my new classmates. Second, I have few friends in my new class. Third, I have trouble learning math. Could you please give me some advice on how to solve my problems?

Yours,

Jenny

Dear Jenny,
