When did Bruce Lee get his black belt?

Answer 1

Bruce Lee never got a black belt or its equivalent. Bruce Lee's core Martial Arts study came from his training in Wing Chun under Hong Kong kung fu master Yip Man (aka Ip Man). The specific amount of time Bruce spent studying under Yip Man is controversial. What we do know is that he didn't complete the Wing Chun system. He was an avid reader, studying books on fencing, boxing, and philosophy. From this, he formulated his art of Jeet Kune Do with Wing Chun at its core. His art (Jeet Kune Do & Wing Chun) is also looked as a process or philosophy of development that has been used as a basis for exploration into creating new methods of fighting. Bruce Lee has been referred to as the father of the sport of MMA. However, Bruce's philosophy had a distinct bias towards realistic self-defense unlike the modern day sport of MMA.

Answer 2

Jackie Chan started studying Hapkido with Grandmaster Jin Pal Kim after Drunken Master was released in 1978. Although no specific date is given it would have been in that period between 1978 and 1982 when Grandmaster Jin Pal Kim moved to the United States.
