Dear Mike，
I'm so glad you're coming to China! Your mother，our foreign English teacher，told me you're worried about what you should and shouldn't do as a guest in China．Here's some advice．You will probably be invited to a big meal. You may find it earlier than you expect because Chinese people eat dinner much earlier than people in the West．There will be a lot of different dishes，not just three courses．You may find it difficult to use chopsticks if you haven't tried before．It's a good idea to get some practice．When the food is served，you should take time to look at it. The preparation takes a long time and everything will look beautiful．The plates will be placed in the middle of the table，for everyone to share．Take a little of everything and then have some more of the things you like．Chinese people like to talk about food，so it's a good topic of conversation．At the end of the meal，you will usually be served with fruit．Eat your fruit，thank your friends， and go．
I hope this is helpful．E-mail me if you have any other questions．
Yours，
David Zhang
