　　Dear Eric,

　　How is everything going? Pm glad to hear that you are coming to spend the Spring Festival with us. Here are some things we are supposed to do during the festival. Before the Spring Festival, we are supposed to clean our houses and buy many things for the New Year. On New Year's Eve, all the family members are supposed to get together and have a big dinner. During the festival, we are supposed to visit the relatives. We are supposed to say "Happy New Year! " to greet each other. "When in Rome, do as the Romans do." If you come to China, please follow the customs.

　　Yours,

　　Wang Wei
