In page Choi Hong-hi:

"

Choi combined elements of Taekkyon and Oh Do Kwan Karate to develop a style of the martial art known as "Taekwondo"; his organization spelt it Taekwon-Do, (태권도; 跆拳道), which means "foot, fist, art" or "the way of hand and foot" and it was so named on 11 April 1955.[1][2] Choi founded the Oh Do Kwan, and held an honorary 4th dan ranking in the Chung Do Kwan. Due to accusations of dishonesty, Choi was stripped of his rank and position in the Chung Do Kwan.[3] During the 1960s, Choi and Nam Tae-hi led the original masters of taekwondo in promoting their martial art around the world, though these would be only the first of many such endeavors.[citation needed]
