I live in a small town near Xing’an in Guilin. You can’t see it on the map of China, because it is too small. The air here is fresh. There are not many tall buildings in our town. The best building is our school. There are four hundred students and twenty-five teachers in our school. In the front of the school, there is a playground. I often play basketball with my classmates on it. There is a little garden behind our school. And we can grow beautiful flowers and plant trees in the garden. Next to the garden, there is an orange orchard（果园）. You can hear birds singing everywhere. There is a river not far from our school. In summer, we usually go swimming with our teachers in it.
