书面表达：
Dear Mike,
    How are you doing? Thank you for your help and good treat while I was traveling in Sydney last summer vacation. You were so kind and friendly to treat us to the local food, and show us around the city. It is really nice to visit Sydney, whose beautiful scenery and delicious food gave me a good impression. I had a great time there and learned a lot about Sydney. Mike, are you free these days? I would like to invite you to visit China. I’ll act as a guide to show you around the places of interest in my hometown.
Looking forward to your reply.

     Yours,
     Li Hua
