We went to Xishan for a outing last Saturday.We had a very good time.We reached at the bottom of the mountain at 9 o'clock in the morning.After a short time rest,we started climbing the mountain.The mountain is so steep and difficult to climb that we had to help each other.It took us one and a half hours to get the top.We felt quite happy on the way back even we were very tired.It was very late when we got home.
