I don't know where to practice martial arts, children's, online and so on.

There are corresponding training courses in university gymnasiums, municipal gymnasiums, children's palaces and some gymnasiums, but there are basically no adult classes in county-level cities.

There is no difference between training courses without foundation.

Generally, many teaching methods are used in clubs, namely Sanda, Taekwondo, Jeet Kune Do and so on.
