Chun Kuk Do

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."

Chun Kuk Do has undergone many name changes, becoming known as Chun Kuk Do in the 1990s and most currently being called the Chuck Norris System.
