Han Moo Kwan

Lee was a student at the Chosun Yun Moo Kwan Kwon Bop Bu (sometimes spelled "Yun Mu Kwan" in English transliteration), learning from its founder, Sang-sap Chun.

Later, after the Korean War Armistice Agreement was signed in 1953, Lee started teaching the returning Yun Moo Kwan Kwon Bop Bu members at the Hankuk Chaeyuk Kwan Dojang.

He had conflicts with Chong-woo Lee and left to start his own annex Kwan by setting up a tent at a high school.

Later, Chong-woo Lee changed the Yun Moo Kwan Kwon Bop Bu's name to Jidokwan.

Korea Han Moo Kwan still exists today, but only as a fraternal social friendship club.
