Wong's first encounter with Bruce Lee was in 1967, in Los Angeles, California, where Lee was giving a Kung Fu seminar. Wong had no martial arts training, and was interested in western boxing and some martial arts. He was so impressed by Lee, however, that he decided to study at Lee's kwoon, the Jun Fan Gung Fu Institute in Los Angeles. Shortly after beginning his studies, Lee accepted Wong as a private student. Wong became Lee's sparring partner and close friend.
