Does Bruce Lee represent Wing Chun? No.
When Bruce came to the U.S. he taught Jun Fan Kung Fu (Bruce Lee Kung Fu).
As he developed JKD, his philosophy toward training, practicing, fighting, and his personal expression he wrote "JKD is pak sao and hip".
Many say Bruce moved away from Wing Chun yet it is obvious he retain much of it. I feel it is more he move away from the CHARACTER and EXPRESSION of wing chun.
He did not eliminate the basic principles of Centerline, Central Line, and Mother Line, three important principles that he learned from wing chun. He did not eliminate Immovable Elbow, for without it the structure is at risk.
He did not eliminate Economy of Movement, and the notion of simplicity. That is very much wing chun.
He did not eliminate the pragmatic approach to simplicity which he learned this from wing chun.
He did not eliminate the concept of flowing with the opponent, and not getting stuck, which is the highest standard wing chun's chi sao training. He did not eliminate the power achieved from the elbows. He did not eliminate the vertical fist in either the straight lead or chain punching. The structure of the vertical fist was stronger, and it not only better closed off the centerline, but it was good for jamming, trapping, and disruption when needed. The weakness of course is the boxer who counters with punches over. With the elbow down, a counter may be in the wind. To combat this, he needed to keep his ability to move the body as a unit, and not just the arm. Of course, this came from wing chun. He didn't eliminate "non-intention," as this was the main principle behind his remarkable speed. Bruce's initial movement was undetectable, because of his non-intention which made him so quick. Bruce may not have had the fastest hand speed in the world, but maybe the fastest start speed. Non-intention. He didn't eliminate his structure even though he modified his stance. Whenever Bruce stood around doing anything, he was almost always practicing the hip structure. It was his hip structure that allowed him perform incredible feats of strength. Remember the photograph of Bruce standing with his arms extended under the bar of the Smith Machine. He wasn't just working isometrics on his forearms, arms and shoulders but, in fact, training the hip. It is the basic structure of wing chun. He didn't eliminate his highly developed sensitivity, nor the strength of his tools that were always in tact for handling pressure and the clinch. He didnāt eliminate his ability to create handles in his opponents for uprooting and disruption. That came from wing chun. He didn't eliminate the stomping power principle for his kicks, though he did modified and added to them.
He didn't eliminate his tools: tan sao, pak sao, bon sao, that came from wing chun. He didn't eliminate the means of how to regain center, if lost. This too, came from wing chun. He didn't eliminate triangular structures in his stance, nor their mechanical advantages, also from wing chun. He didn't eliminate the principle of jing power, so important for deeper penetration and add power and speed, so importantly stressed in wing chun. He didnāt' eliminate his hip structure, even when modifying his stance. It was still there when needed. It was built in. It came from wing chun. He didn't eliminate the fundamentals of body unity, learned from wing chun for delivering his final power or holding and exerting pressure. He didn't eliminate his original concept of timing, learned from wing chun and later developed into added drills and expanded upon. He didn't eliminate the concept of hand before body. That was wing chun. He didn't completely eliminate lin sil dar, simultaneous attack/defense. That was wing chun. He never eliminated the concept of two guns facing, even though he had modified his stance to quarter facing. In this way, he neither weakened his structure nor permitted over swing back. He two guns principle were still in tact and dangerous. Also the modified stance stood a better chance against a grappler. He didn't eliminate the concept of pak sao, which is much more than slapping hand, but how to intercept and/or cut off. Thus, "the way of the intercepting fist.
Bruce represents his arts Jun Fan Gung Fu and his expression of what he learned and how he trained as Jeet Kune Do.
