Dear Peter,
I'm writing to you to ask for a favor. Could you please help me to buy a book, Gift from the Sea, written by Anne Lindbergh? The book is very important for me. I need it to refer to when I write my term paper. I have looked for the book for many days, but I can not find it in local area. Please mail it to School of English, Beijing City University if you get it. The postcode is 10000. Besides, please tell me how I can transfer the money to you. I will be appreciated if you can help me.
Looking forward to your reply.
Yours,
Li Hua
