You can go to five kilometers Technology and Business University to study, where coach Li is a foreigner and a very professional tennis coach. I didn't study there at first, but I studied at the tennis professional teacher for a while, because I was a physical education teacher, but I didn't learn anything. When I was about to graduate, I transferred to coach Li. His movements are in place, his theoretical knowledge is strong, his teaching is really good and he has a deep understanding of tennis. With his sentence "When I decide to be a tennis coach, I will never let others beat me in tennis teaching", I think it is worth recommending. So I think you can consider him, which is also very convenient for you. Introduction to tennis is very important. Don't learn bad movements, it's hard to change them. In the past, we were transferred by three people together, and the price was very cost-effective. It seems that dozens of people still can't remember clearly. They seem to be the airship tennis club now.
