These 12 practitioners then were considered original to the new martial art. In alphabetical order, the Original Masters are: Choi Chang Keun, Choi Kwang Jo, Han Cha Kyo, Kim Jong Chan, Kim Kwang Il, Kong Young Il, Park Jong Soo, Park Jung Tae, Park Sun Jae, Rhee Chong Chul, Rhee Chong Hyup, and Rhee Ki Ha .
