Don't worry about the quality of taekwondo gym. At present, China Taekwondo Association has strict requirements for the establishment of every Taekwondo club.
For example, the curator must be named by four black belts. All coaches must obtain the qualification certificate issued by Taekwondo Association.
So at least the existing Taoist temple should be formal. Otherwise, it would be strange not to be kicked, and the consequences will be very serious.
I suggest you enter "the name of the area where you live" and "Taekwondo Hall" in Urumqi, Xinjiang in Baidu, and find the nearest one first. As I wrote before, we can discuss with the coach whether we can try it for a few days.
At present, if you practice three times a week, the annual fee is generally around 2500.
I hope the above suggestions will help you.
