It's ridiculous that you said there was no sufficient evidence to say that volley boxing was used in street fighting and actual combat. . How did you teach yourself? Jeet Kune Do has no fixed moves, so there is no way. You can say it has no form, or you can say it is any form. You said you couldn't convince your classmates with any evidence. It's simple. You can let him go to Bruce Lee movies to learn whether Jeet Kune Do can be used, how to use it in the street and in actual combat, or some movies about Zhen Chen. You have no practical skills in teaching law by yourself. What impressed me most when I learned Jeet Kune Do was that you should treat yourself as a water bottle, and accept, adapt and control the environment no matter what kind of liquid enters your body.
You didn't choose the wrong project. Jeet Kune Do is a good martial art and a very scientific knowledge. Come on, practice hard, only hard training can get the desired results, come on ~ my classmates.
