I went to Mount Fanjing with my classmates two years ago. That impressed me was climbing the mountain.It was the late spring and it was a little cold in the mountain. The mountain was such steep that we could hardly climb to the top of the mountain. In the process of climbing, I was too tired to go on climbing. But when I saw other student trying their best to climb, I made up my mind to be the first one to climb to the top. Then I picked up a branch of a tree to support me. Unluckily, I slipped and fell down. At the critically moment, one classmate hold me so I did not fall off the mountain. Under their help, I finally climbed to the top of the mountain.
I was very exciting because it was the first time I had climbed a mountain. Meanwhile, I understood that we should help each other when we were in trouble. This trip came to an end soon, but it still encourages me overcome the difficulties I face.
