Choong-Moo was the name given to the great Admiral Yi Soon-Sin of the Lee Dynasty.
He was reputed to have invented the first armoured battleship (Kobukson) in 1592,
which is said to be the precursor of the present day submarine. The reason why this pattern ends
with a left hand attack is to symbolize his regrettable death, having no chance to show his
unrestrained potentiality, checked by the forced reservation of his loyalty to the king.
It is the first pattern to incorporate a flying technique and a stationary jump turn.
It is also the pattern performed when grading for 1st Dan/Degree Black Belt.
