Dear Li Hua,

    I will come to Nanjing in July and stay with a Chinese family for a week as an exchange student. To get along well with my host family, should I prepare any gifts? How can I help with the housework? What else should I do?

    Please write back soon.

Yours, John

Dear John,

Li Hua
