Guangming High School is in the west of the city，with the Chengxi River running nearby. It covers an area of 130 mu. When you enter the school， you can see a big flower bed in front of you，and two large buildings on both sides- the library on your right and the teaching building on your left. Walking on further，you will find the gymnasium， which is the most beautiful building on the campus， with another round flower bed in front. Behind it， there lie four basketball courts. Next to the courts is the sports ground. Along its east side stand three buildings-the dining hall， and two dormitories for the students and teachers. All the buildings are surrounded by bushes and flowers.
