I found this article on Bruce Lee's encounter with Wong Jack Man interesting.
Who knows what really happened? But I see there's a entire book written about the event (and an upcoming movie?)
From the article, one of Wong Jack Man's students was Peter Ralston, whose book I bought years ago. Ralston has apparently transcended martial arts, but has a youtube channel.
OK, how about his fight with Lau Dai-Chuen?
