Choong-Moo was the name given to the great Admiral Yi Sun-sin of the Yi Dynasty. He was reputed to have invented the first armored battleship (Kobukson) in 1592, which is said to be the precursor of the present day submarine. The reason for this pattern ending in a left hand attack is to symbolize his regrettable death. Checked by the forced reservation of his loyalty to the King, Yi Sun-Sin was given no chance in his lifetime to show his unrestrained potentiality.
