The development of Jun Fan Kung Fu, or Jeet Kune Do, under the tutelage of the great Bruce Lee, saw the incorporation of various elements from diverse martial arts traditions. One such influence was the art of fencing, which Lee had acquired a taste for at a tender age, thanks to his brother's involvement in the sport. The footwork and techniques associated with fencing were duly assimilated into Lee's modified Wing Chun style, which formed the foundation of Jeet Kune Do.

Notably, the fencing influence on Jeet Kune Do can be seen in the one-foot-behind-the-other stance and the Parry hit technique, which deflects the opponent's attacks while delivering a counter-attack simultaneously. However, it would be erroneous to suggest that fencing is the sole inspiration for Jeet Kune Do, as the martial art is an amalgam of various disciplines.

In addition to fencing, Bruce Lee was also influenced by Wing Chun Kung Fu, a traditional Chinese martial art that emphasizes close-range combat and rapid-fire punches. The incorporation of techniques from Wing Chun Kung Fu added a new dimension to Lee's modified Wing Chun style, leading to the emergence of Jeet Kune Do, a revolutionary martial art that emphasized constant improvement and evolution.

It is imperative to recognize that while Bruce Lee did integrate certain components from fencing into Jeet Kune Do, it is not accurate to assert that Jeet Kune Do is entirely founded upon fencing. Bruce Lee's martial arts style was an amalgamation of various techniques, and he persistently strived to perfect and advance his craft.

Another influential factor in Bruce Lee's fighting style was Wing Chun Kung Fu. Wing Chun Kung Fu is a traditional Chinese martial art that concentrates on close-range combat and rapid, successive punches. Bruce Lee extensively studied and incorporated many of Wing Chun's techniques into his personalized Wing Chun style.

Bruce Lee's Jun Fan Kung Fu, or Jeet Kune Do, is a martial arts style that continues to serve as a source of inspiration and guidance for martial artists globally. By assimilating different techniques from a variety of martial arts styles, including fencing and Wing Chun Kung Fu, Bruce Lee was able to establish a distinct and efficient fighting style that remains applicable in contemporary times.

The legacy of Bruce Lee is still influential and has continued to inspire martial artists around the world. His unique approach to martial arts, which assimilated elements from various traditions, is still applicable today. The inception of Jeet Kune Do is a testament to Bruce Lee's genius and his emphasis on integrating diverse martial arts styles, which has contributed significantly to the advancement of martial arts.
