关于拿错笔记本的

Dear Jack,

　　In June when you were visiting Beijing,on the last day of your trip a fare well party was given at the Youth Palace.At the party I sat next to you.Then at the end when we went away we took each other's notebook by mistake.I discovered this only afterwards when I looked into the notebook and found your name and address inside.I'm now sending your notebook by post to you.Will you please send my notebook to me at the address which is given in my letter? Thank you very much.

　　I hope you will visit Beijing again soon.

　　Your Chinese friend,

　　Li Hua
