I spent less than 6 minutes researching this...
Jack Man Wong does not belie[ve] Bruce would actually fight, and tries to delay the match. Bruce becomes angered and insists that they not wait. Wong then tries to put limitations on techniques. Bruce refuses "rules"and the two go no holds barred. Bruce begins to pound his opponent in only a couple of seconds. As Bruce is winning, Wong attemps to flee, but is caught by Bruce. Bruce begins to beat him on the ground. Students of the other teacher attempted to step in and help their teacher, James Lee, Bruce's good friend prevent this. Later he is bothered on why the fight took so long and begins to re-evaluate his style.
Cheers, hope that clears thing up.
