General Choi developed twenty-four Taekwon-Do patterns. He chose the number 24 to correspond to the 24 hours in the day, a continuously repeated cycle that represents eternity. He named each pattern (except Chon-Ji) after important people in Korean history, as a reminder of the importance of honoring and cultivating respect for those who have accomplished great things. For certain patterns, the shape of the diagram and the total number of movements representing the pattern are also significant. A Taekwon-Do pattern is a sequence of fundamental movements in an imaginary fight against one attacker or several. The execution of the movements requires the application of the Theory of Power. Correct breathing generates internal energy, which increases power.
