Many people have asked similar questions, and I won't give completely different answers to the same questions. Therefore, some questioners always ignore the ID after reading my previous answers and say that I copied it. I just delete the details on the basis of the corresponding answers, and then answer according to the questioner's requirements. If you feel that this answer is missing, you can add questions or ask questions.

I have encountered many such problems, and most of them have miscarried, because the people there are basically unclear, so no one will give you a detailed address or way, only the way to find it.

General city and university gyms can find relevant training courses.

You will have more such problems in the summer vacation, but I want to tell you that the real training time in a summer vacation is only over a month, and you can't learn much. What's more, you need daily practice, saying that self-defense is a gimmick.
