Jeek Kune Do, is a martial art and life philosophy founded by philosopher, martial artist, and actor Bruce Lee. It´s not a style of martial arts like other more traditional arts. What sets Jeet Kune Do apart from traditional styles of martial arts is that it´s not fixed or patterned. It is a philosophy with guiding thoughts.
Jun Fan Jeet Kune Do is used to refer to the martial arts system that Lee founded. "Jun Fan" was Lee's Chinese given name, so the literal translation is "Bruce Lee's Way of the Intercepting Fist."
