Jun Fan Gung-Fu -​振藩功夫-

What is JunFan Gung-Fu?

Jun Fan Gung-Fu is a martial art in which Bruce Lee modified Wing Chun for use in a real fight and incorporated his experiences of other martial arts and combative sports.


Nevertheless, the core techniques of Jun Fan Gung-Fu still derived from Wing Chun. It consists of curve line approaches in addition to Wing Chun’s short straight strikes.


* “Jun Fan” is the Chinese name of Bruce Lee.


In 1962, with the efforts mentioned above, Bruce Lee opened a martial arts school named “Jun Fan Gung-Fu Institute.”


Jun Fan Gung-Fu is a fusion of offensive and defensive techniques. The main techniques are Contact methods(接触法) and Crossing methods(交叉法), which enable one to suppress the opponent’s guarding hands and then attack (strike, throw or Qin Na(擒拿)).

The History of JunFan Gung-Fu
《 1965~1966》

·Bruce Lee began to research martial-arts/combative-sports other than Chinese martial arts by exchanging ideas with these practitioners and reading related books with profound insight.

It did not mean simply combining other countries’ techniques on a superficial level, but studying their true nature, namely scientific principles, and uniquely modifying them to make further development.


At this time, he was particularly focused on fencing and boxing.

《 1967》

·Bruce Lee opened the third Jun Fan Gun-Fu Institute in Los Angeles.

In the summer of that year, he started to use the name

“Jeet Kune Do,” which originated from the fighting methods that he had developed.


At the time, the basic structures and techniques of Jeet Kune Do were not yet fully established.

《 1968~1969》

·From August 1967, while Bruce Lee gradually developed Jeet Kune Do with Ted Wong, who was both a private student and a workout/sparring partner, he was teaching an evolved form of Jung Fan Gung-Fu in institutes and semi-private lessons.

《 1970》

·Bruce Lee closed all of the institutes and stopped teaching Jun Fan Gung-Fu.

The evolution of Jan Fan Gung-Fu stopped at this time.

After that, he only taught Jeet Kune Do through private lessons.

《 1964》

·In 1964, Bruce Lee opened the second Jun Fan Gung-Fu Institute in Oakland.
