Chon Ji means literally the "Heaven and the Earth". It is, in the Orient interpreted as the creation of the world or the beginning of human history, therefore it is the initial pattern practised by the beginner. This pattern consists of two similar parts, one to represent the Heaven, the other Earth.
Yul Gok is the pseudonym of the great philosopher and scholar Yi I (1536 – 1584), nicknamed the ´Confucious of Korea´. The 38 movements of this pattern refer to his birthplace on the line of 38 degrees latitude, and the diagram represents "scholar".
Joong Gun is named after the patriot Ahn Joong Gun who assassinated Hiro-Bumi Ito, the first Japanese-Governor General of Korea. Known as the man who played the leading part of the Korea-Japan merger. There are 32 movements in this pattern to represent Mr Ahn´s age when he was executed in Lui-Shung prison in 1910.
Toi Gye is the penname of the noted scholar Yi Hwang (16th Century), an authority on neo-Confucianism. The 37 movements of this pattern refer to his birthplace on the 37th degree latitude. The diagram represents "scholar".
Hwa Rang is named after the Hwa Rang Youth Group, which originated in the Silla Dynasty in the early 7th century. The 29 movements refer to the 29th Infantry Division where Tae Kwon-Do developed into maturity.
Choong Moo was given to the great Admiral Yi Soon-Sin of Lee Dynasty. He invented the first armored battleship (Kobukson) in 1592, which is said to be the precursor of the present day submarine.
