Chon-Ji is the first of the 24 traditional Taekwondo patterns. It means heaven and earth. Thus representing the red energy of Yang and the blue complimentary energy of Um. It lays the fundamentals for the Taekwondo practitioner to build on and in this aspect it is the beginning of all things in Taekwondo, as before you can have a kingdom you must have a land under the heaven. The pattern is relatively simple, only consisting of three(or four if you count the start position of narani junbi sogi) techniques. These techniques are niunja so an palmok kaunde yop magki, the L-stance outward upper body block, gunnun so bakat palmok najunde magki, the low outwards block and gunnon so ap joomuk kaunde baro jirugi, the mid front punch. This divides the patterns into three sections, first practicing lower body blocks, taking care of the earth, and upperbody blocks, taking care of the heavens. The third section only relies on punching, but has the practitioner walk backwards for a change. When moving from one technique to the next the student slides his leading foot in a crescent motion. At the same time it is about understanding complimentary forces. One uses the wide stance, focusing energy forward by bending the front knee, and the L-stance, focusing energy backwards by bending the hind knee. If the practitioner doesn't control this energy in the body they will not end up in their starting spot. The pattern also stresses technical precision, another determining factor for ending up in the starting spot is keeping the shoulder distance in the legs present throughout the pattern. Both of these details are of massive importance, for keeping balance and maintaining control of the body-mass, using legwork in a real fight. A good exercise routine to go along with Chon-Ji is practicing footwork with a partner. Using the crescent motion of the leading foot to skid you into the direction you want to go, as the partner moves forwards you move backward, as the partner sidesteps to the left you sidestep to the right and so on. The goal is to get a good feel of the momentum in your body and the surface underneath your feet. Another example that is a bit more direct is varying between L-stance and wide-stance in an actual fight. Using the legwork to hopefully bring you in and out of punching range. In the example provided here the practitioner is in a wide stance sparring against a partner in neutral stance. As the partner tries to punch him he leans back into niunja so an palmok kaunde yop magki, keeping his foot in a calculated range. Since he has placed his front leg well, when he thrusts back into wide-stance and punches, he hits his partner in the chest, while keeping the blocking hand at his side, cleaning the partners punch out of the way with a twist of the hip. A second defense-technique that is almost obligatory no matter what martial art you practice is the sprawl. Movement 18 and 19 of Chon-Ji gives a great fundament to build on when incorporating this move to your reportoir. As the opponent drops down to grab your front leg you lean on his back and sprawl your legs back, landing on his back, pushing him down with your wheight. From this position you can easily deliver powerful elbows to the lumbosacral columna and kidneys on the sides. Chon-Ji on it's own, like a defense-system would consist solely on dodging using footwork and retaliating with punching while avoiding and punishing takedown attempts. Capitalizing on an attackers sloppy technique, utilizing knowledge of range and footwork to land a good hit and run off. this would work on one of those guys whos main tactics is to try and punch your, then get really mad and ram into you, like Ron from the Jersey Shore. Here is also a nice drawing of Il-yeo I made a while back, just wanted to show it of. It is of to poor quality to be used for anything descriptive.
