You don't need to go through the formalities, my friend. This thing is not a shop or anything. You need hygiene license, business license and so on. As long as you open this basketball training class, it won't affect others, and it won't cause any public impact, such as hygiene. So you must do these things well, so that others will not complain about you. I have a friend who is doing this now, but the scale is not large, about 20 people, regardless of age, teach outdoors, which is very convenient and the teaching time is very regular, so as not to affect others' rest as much as possible.
