China University of Science and Technology, the price is not bad. In fact, you want to study 10 days, but there is no such crash course. My personal suggestion is this: go to the city gymnasium or the Chinese University of Science and Technology, go to the deep water area, see a better tour, go up and chat up directly, ask if you have time, ask others to teach you skills, and tell others that you want to study 10 days. There are usually good teachers. Come on!
