龍爭虎鬥
Some sources claim that Wong choreographed some fight scenes in "Enter the Dragon" (龍爭虎鬥), saying that "... when shooting "Enter the Dragon" in Hong Kong, he [Bruce Lee] invited Wong to come on location to discuss the fight scenes" and that "Wong in fact had been invited to choreograph some of the fight scenes in "Enter the Dragon". The documentary "Dragon since 1973" consists of interviews with various Hong Kong personalities, mostly those who worked with Lee in his Golden Harvest days. None of the interviewees, including Bee Chan (陳會毅; one of Lee's most trusted assistants), Shek Kin (石堅), and Chaplin Chang (張欽鵬), mentioned that Wong had been invited to work as a fight scene choreographer for "Enter the Dragon".
