In order to promote participation in outdoor exercise, our school had organized an activity to climb the West Mountain on April 10. The moment we arrived at the foot of a mountain, we set out for the top in high spirit. We supported each other to pass the rocky areas on the course of the climb. Laughing and cheering, we eventually reached the summit, there we were greeted by the bright sunshine and fresh air. Viewing from the top, the city was extremely beautiful This event was very benefit, for not only we take a break from our heavy school workload, but we also learned what to cooperate. Therefore, we strongly suggest that similar events are held every year!
