Yes, there is a Zilong Dojo in the stadium called Taekwondo, and the price is not clear. There is a rising star Taekwondo Hall on the third floor of Shengde Building (the one in Liqun East). 400 yuan is one hour a month, six days a week. If you only go on weekends, it's only 260 a month, which is a bit expensive. There seems to be one above Liqun. I have never been there before. Look at the billboard downstairs. You can go on a field trip.
