Hoi Jeon Moo Sool (HJMS) is a Korean martial art developed by Myung Jae-Ok, largely based on Hapkido. "Hoi Jeon" means circular, and "Moo Sool" means martial art. The art uses circular movements for both defense and attack, the intent of which is to use the opponent's energy against him.
Hoi Jeon Moo Sool places its emphasis on close-range techniques such as locks and throws. Strikes, blocks, and kicks are also used however.
