Chun Kuk Do

The name was Chun Kuk Do from 1990 until July 2015. In July 2015 it was renamed Chuck Norris System.

Chun Kuk Do (Hangul: 천국도; Hanja: 天國道, commonly abbreviated as CKD) is a martial art (or type of fighting style) that Chuck Norris created. It is said to be based upon Tang Soo Do, another martial art.

Chun Kuk Do mainly means "The Universal Way," but has other meanings, such as, "The Way of 1000 Lands," or "The Way of Many Lands."
