Growing up in Hong Kong, Lee was a student of Wing Chun Grandmaster Ip Man. However, in America he called what he taught Jun Fan Gung Fu[a][1][2][3][4] However, around 1964, following his encounter with Wong Jack-man, Lee disavowed the rigidity of systematized martial arts.[5][6] Following this, Lee began a journey of research in order to refine his way of practicing martial arts. In 1965, he outlined the basic concepts of Jeet Kune Do in a press interview,[7] but it was not until 1967 that he came up with the name Jeet Kune Do. Initially, Lee wrestled with putting a name to his art as he constantly veered away from any type of crystallization of its essence; however, the simple need to refer to it in some concrete way led him to decide upon a name for it.[citation needed]
