Chon-Ji means literally "the Heaven 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 played by the beginner.This pattern consists of two similar parts;
one to represent the Heaven and the other the Earth.
Chon-Ji is the first Taekwon-do pattern taught to students, it is learnt by those who have passed their first grading.
