Wing Chun Warrior: The True Tales of Wing Chun Kung Fu Master Duncan Leung, Bruce Lee's Fighting Companion. Duncan Leung was introduced to Wing Chun Kung Fu by his childhood friend, famed screen star Bruce Lee. At the age of 13, he became the formal disciple of sixth-generation Wing Chun master Yip Man. In 1964 Leung befriended an old man who taught him rare secrets of close fighting, including the art of disarming a knife-wielding opponent, and silencing an opponent barehanded. When he opened his Wing Chun studio in New York City in 1974, he was challenged by martial art practitioners of every school but remained undefeated. Since moving to Virginia Beach in 1976, he has taught US Navy SEALs, members of the FBI, and various SWAT teams.
