I was glad to have this opportunity to learn outdoor in Nam Chung. This field trip not only helps me to learn lots of extra knowledge about river but also helps me to broaden my sights. I tried to ask question and after Mr. Leung's explanation, I get lots of information of river in Nam Chung. Although the weather is extremely hot, my group members also enjoy this trip so much. I like the water in there so much because it is very clean in there. I saw the pothole and waterfall. They are very interesting and marvelous. However, I also have difficulties during this trip because the stones are much slipped. Some of our classmates fell down. It is unforgettable field trip. I wanted to thank my teachers and my members' supports.
