Ko-dang

Ko-Dang was the eighteenth hyung of the Chang-Hon School of Taekwondo. The original Chang-hon pattern set had 20 patterns, but General Choi Hong Hi  of the International Taekwondo Federation (ITF) dropped Ko-Dang and added Eui-Am, Moon-Moo, Ju-Che, So-San, and Yon-Gae. Some organizations, such as Taekwondo America, still use Ko-Dang.

Ko-Dang is the pseudonym of the patriot Cho Man-Sik who dedicated his life to the independence movement and education of Korea.

Cho Man-sik (1 February 1883 – October? 1950) was an activist in Korea's independence movement. He became involved in the power struggle that enveloped Korea in the months following the Japanese surrender after World War II, but was eventually forced from power by the Soviet-backed communists in the north. Placed under house arrest in 1946, he later disappeared into the North Korean prison system, where he is generally believed to have been executed.
