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.
