We have meals in our school canteen every day. There are various dishes in it, range from organic vegetables to freshly meat. Not only are dishes tasty, but also rich on nutrition. The vegetables planting in the school backyard garden included cabbages, carrots, tomatoes and so on. We assist the gardeners to water and weed the fields in their spare time. Moreover, we learn to feed chickens and pigs on the farm outside our school, that adds a great deal of funs to our school life. With a rich and colorful school life, and we are able to learn by playing and play by learning.
