Ing-Sik Whang is a Grandmaster of hapkido and a student of legendary hapkido Grandmaster Ji Han-jae (generally regarded as one of the two "fathers" of hapkido). For those who may be unaware, hapkido is a Korean martial art employing both grappling and striking techniques to disable an opponent.To film audiences, Ing-Sik Whang is perhaps best remembered as the final villain whom Jackie Chan ends up defeating in Shi di chu ma (1980) and its sequel, Lung siu yeh (1982). Ing-Sik Whang has made over 25 appearances in feature films and currently runs a hapkido academy in Canada. Show less «
