Every year at our school, we have a special day called International Day (国际日). It is for students to learn about different cultures (文化) from different countries. On this day, each class must tell other classes about a different country. Of course you will see many dances and different foods.

If you visit the classroom of Japan, you can play the games Japanese children play. You also have some special Japanese foods. In the classroom of Mexico (墨西哥), there are tomalleys (龙虾肝) and chips to eat.

In the afternoon, all the students, teachers and parents watch the dances. There are lots of dances. These dances are beautiful. People enjoy the shows.

I enjoy International Day very much.
