Rowing boats are always a fun activity for me. Last summer I went to Hainan with my father and spent a week there. We stayed in a hotel which was short distance from the sea. On the five day, my father hired a boat. Look around, I found there were not many more boats on the sea. I wanted to row of my own, but my father was afraid to let us do that. He didn't agree unless later a boatman came and helpfully taught me how to row. I was very pride when I was finally able to row the boats and keep it on course.
