Choong-Moo is an ITF-style teul (form) named after the great Admiral Yi Soon-Sin of Korea's Yi Dynasty. Yi is credited for saving Choson Korea from the brink of collapse during the Japanese invasion of 1592. Yi is also reputed to have invented the first armored battleship (Kobukson, nicknamed the "Turtle Ship") in the year 1592. In all of his 23 major naval battles, Yi was never defeated.

In his book, The Influence of Sea on the Political History of Japan, George Alexander Ballard, a vice-admiral of the British Royal Navy, summarized Yi’s life and victories as follows:

It is always difficult for Englishmen to admit that Nelson ever had an equal in his profession, but if any man is entitled to be so regarded, it should be this great naval commander of Asiatic race who never knew defeat and died in the presence of the enemy; of whose movements a track-chart might be compiled from the wrecks of hundreds of Japanese ships lying with their valiant crews at the bottom of the sea, off the coasts of the Korean peninsula...and it seems, in truth, no exaggeration to assert that from first to last he never made a mistake, for his work was so complete under each variety of circumstances as to defy criticism... His whole career might be summarized by saying that, although he had no lessons from past history to serve as a guide, he waged war on the sea as it should be waged if it is to produce definite results, and ended by making the supreme sacrifice of a defender of his country.

Yi is still dearly cherished in the hearts of Koreans today. In a nationwide survey conducted by Soonchunhyang University in April 2005, Yi Sun-sin was chosen as the greatest figure in Korean history by 43.8% of the vote (source: The Chosun Daily, April 15, 2005).


ITF Taekwon-do forms often come in two styles: Sine Wave and non-Sine Wave. In either case, the basic movements are the same. The difference is in the "up and down" motion that's used (or not), the rhythm of the movements, and the breathing. See main article Sine Wave for additional details.
