I went to Xiang Shan Park to climb the hill with my friends last winter. It was a good trip at the beginning, but something unexpected happened on the half way. One of my friends got a stomachache and couldn't move any longer. One girl tried to phone her mother with her mobile phone, but there was no signal in the mountain area. Luckily, one of us took some medicine for the trip. We asked him to have a rest by the side of the path.Someone took some medicine and let him have it. Then he drank some water. After a while he felt much better and we walked on.We all enjoyed ourselves at the top of the mountain.
