My friend, in this era when the whole world is learning Taekwondo, you can choose Judo, an unpretentious fighting skill. Very practical, but I haven't heard of it. There are formal judo gymnasiums in Ningbo, but many martial arts gymnasiums or gymnasiums have judo classes, but the effect is not good. If there is no judo class, I suggest you go to a sports school and contact a judo coach. It's a good way. Some sports schools will accept summer students! Try it, my friend.
