I will take personal eyewitness accounts:
In Oakland, Bruce would only have two witnesses: his recent bride Linda Lee (who was 8 months pregnant at the time) and his close colleague James Lee (who had a loaded handgun nearby in case things spiraled out of control). This made for a total of nine people in the room, only three of whom are alive today. With a couple of very rare exceptions, Wong Jack Man has stayed perennially quiet on the matter. Linda Lee and David Chin, who were on opposing sides of the conflict, give a generally similar account: the fight was fast and furious, spilling wildly around the room. The exchange was crude, and far from cinematic. After landing an opening blow on Wong’s temple, Bruce struggled to decisively put away his evasive opponent like he had in Seattle a few years earlier, and quickly found himself heavily winded by the encounter.
Eventually Bruce’s relentless advance caused Wong to stumble over a small step, into an untenable position on the floor where Bruce hollered “Do you yield?” in Cantonese over and over while pummeling him repeatedly. Having lost his footing, Wong had no choice but to concede. “From there, he said he gives up and we stopped the fight,” recalls David Chin. “The whole thing lasted…not more than seven minutes.”
Either way the fight is meaningless because who the fuck is Wong Jack Man...no one cares. The story has little significance with respect to the actual fight.
The fight significance is that it sparked the idea of changing his training regiment and endurance. That is all.
Also, the other schools stopped harassing him for teaching outsiders.
