Jeet Kune Do , or "The way of the intercepting fist" in Cantonese, abbreviated JKD, is a hybrid philosophy of martial arts heavily influenced by the personal philosophy and experiences of martial artist Bruce Lee. Lee founded the system on July 9, 1967, referring to it as "non-classical", suggesting that it is a formless form of Chinese Kung Fu. Unlike more traditional martial arts, Jeet Kune Do is not fixed or patterned and is a philosophy with guiding ideas. Named for the Wing Chun concept of interception or attacking when one's opponent is about to attack, Jeet Kune Do's practitioners believe in minimal effort with maximum effect and extreme speed. On January 10, 1996, the Bruce Lee Foundation decided to use the name Jun Fan Jeet Kune Do (振藩截拳道) to refer to the martial arts system which Lee founded; "Jun Fan" being Lee's Chinese given name. It is referenced in the screenplay of the 1973 Warner Brothers film Enter the Dragon, when Lee is asked, "What's your style?", he replies, "My style?...You can call it the art of fighting without fighting."
