Dr. Leung first started teaching Wing Chun in Foshan/Fatshan, where he ran his successful medical practice/pharmacy. Late Grandmaster and Ip Man’s teacher, Chan Wah Shun, was one of Dr. Leung’s top students. During that time, Foshan was the melting pot of Southern Style Kung Fu. Ip Man’s lineage largely came from Dr. Leung’s teachings in Foshan during this time. The Foshan line of Wing Chun became very popular because of Ip Man and the late Bruce Lee.
