Dear John,
How's it going ? I'm very glad to hear from you . You say you want to learn some customs and manners about being a guest in a Chinese family. Now let me tell you something .
People greet each other when twe meet for the first time .But we don't kiss or hug each other .
When you go to a Chinese friend's home ,you can bring some presents such as some food,fruit and flowers .The host won't open the present until the guest leaves .
We Chinese use chopsticks when we eating . All the people sit around the table and share the delicious foods ,laughing and talking with each other.
