There is a martial arts association in Tianjin Engineering Normal University (now renamed Tianjin Vocational and Technical Normal University) in Hexi, which is very good and formal. He has won the excellent club of Tianjin university students and the prize of Tianjin Taekwondo Championship for many times. The coach is also responsible. What is commendable is that the coaches in the association are all voluntary, so the tuition is quite cheap. I suggest you try.
