Hi, Louis!

I’m writing to tell you something about the customs(风俗) and festivals.

Everyone loves holidays since one doesn’t need to go to school or work. Although all holidays mean no school and work, but not all of them are the same. On some of them you go out with friends; on others you stay home to eat, talk, and have fun with your family. For example in the USA, everyone thinks New Year’s Eve and New Year are both for playing with friends. Christmas is the time to stay home and exchange gifts with family members. The opposite (相反) is true in Japan though. For example, in Japan, New Year is for spending time with the family to eat, talk, have fun, and go to the temples. But Christmas is for boy and girl friends to go out and exchange gifts. Originally Christmas should be to celebrate(庆祝) the birth of Christ.

I have been interested in foreign customs since I was little. If you learn these different holiday customs, you will learn about different histories and cultures. This is much more interesting than learning them at the library from morning to evening.

Loves,
