What's the difference between extreme karate and other traditional karate?

Kungfu Hall is a karate martial arts association founded by Oshima Beida (a Korean who went to Japan at the age of fifteen and lived in the northeast of China as a child) in Japan from 65438 to 0965. Up to now, the Dojo is distributed in more than 20 countries around the world, with more than120,000 students. The biggest difference between extreme reality club and other karate is that it is based on actual combat and is famous for its full contact competition. The two boxers basically don't wear any protective gear and gloves, but their hands can't start and their legs can kick their heads. Of course, you can't hit the yin, eyes, throat and other key parts.
