Beyond Won Kuk Lee, several other practitioners formed kwans in the area. By the 1960s, there were nine major kwans, which were based on an original five: 1) the Chung Do Kwan (Won Kuk Lee), 2) Moo Duk Kwan (Hwang Kee), 3) Song Moo Kwan (Ro Byung Jick), 4) Chang Moo Kwan (Yoon Byung-In), and 5) Jidokwan (Chun Sang Sup). Chun's original style, Yun Mu Kwan karate ("kongsudo" in Korean) became "Jidokwan" when his students found new teachers after his disappearance in the Korean War and the new name (meaning "Hall of Wisdom's Way") was adopted.
