Which martial arts did Bruce Lee know?

Lee Jun-fan (November 27, 1940 – July 20, 1973), commonly known as Bruce Lee, was a Hong Kong American actor, director, martial artist, martial arts instructor and philosopher.

Lee is considered by commentators, critics, media, and other martial artists to be the most influential martial artist of all time and a pop culture icon of the 20th century, who bridged the gap between East and West. He is credited with helping to change the way Asians were presented in American films.

Lee called what he taught Jun Fan Gung Fu (literally Bruce Lee's Kung Fu). He trained in the art of Wing Chun (a concept-based traditional Southern Chinese Kung fu) and later combined his other influences from various sources into the spirit of his personal martial arts philosophy.

He initially introduced kung fu to the West with American television shows such as The Green Hornet and Kung Fu, before the "kung fu craze" began with the dominance of Hong Kong martial arts films in 1973. Lee's success subsequently inspired a wave of Western martial arts films and television shows throughout the 1970s–1990s (launching the careers of Western martial arts stars such as Jean-Claude Van Damme, Steven Seagal and Chuck Norris), as well as the more general integration of Asian martial arts into Western action films and television shows during the 1980s–1990s.
