It is a highly eclectic Korean martial art. It is a form of self-defense that employs similar joint locks, grappling and throwing techniques to other martial arts, as well as kicks, punches, and other striking attacks.
Hapkido evolved during the mid-20th century by selectively fusing a wide range of existing martial arts with new ideas and techniques by a man name Choi Yong Sul.
Ji Han-Jae was born in Andong, Gyeongsangbuk-do, South Korea in 1936. He is one of the highest ranking hapkido instructors in the world and founder of Sin Moo Hapkido.
