He was also the first Korean instructor in open a Chung Do Kwan school outside Korea, in Japan on 1952, and vice president of the World Taekwondo Association.
While his family had been highly respected and part of the educated class they lost everything during the Japanese occupation and, like most during that time, struggled for survival.
Not until he was a young man, at the age of 25, did Chung begin to train in the art of Tang Soo Do under the instruction of Lee Won-kuk.
In 1974 Chung decided to bring his expertise to Kansas City, Missouri in the United States and aligned with the World Tae Kwon Do Association under Son Duk-son in which he served as a vice president.
A 9th Degree Black Belt, Chung devoted his entire life to the mastery and teaching of Tae Kwon Do.
