Kong Soo Do

Kong Soo Do (공수도) is a name used to refer to Korean martial arts derived from Karate, that was used by a couple of the original kwans before the unification and creation of Taekwondo as the universal striking art of Korea. As with Tang Soo Do, the name Kong Soo Do is composed of the Korean pronunciation of the Chinese characters for "karate-do", meaning "empty-hand way" in English.

Kong Soo Do is a not a formalized system of martial arts, and the styles used by the various kwans are influenced by the individual backgrounds of the respective founders/head instructors. The name Kong Soo Do was used by Yun Mu Kwan (sometimes Yun Moo Kwan Kong Soo Do Bu, Hanja: 朝鮮硏武館 拳法部) and the YMCA Kwon Bop Bu (later named Chang Moo Kwan) to refer to their martial art.
