The attack is executed in the form of punching, striking, thrusting, cross cutting, pressing and breaking. Since three of these techniques – punch, strike and thrust – are so closely interrelated in principle, it may be difficult to make a clear distinction among them. The purpose behind each technique, as well as the method, differs slightly. A punch is used primarily to case an internal hemorrhage rather then surface damage by twisting the attacking tool. A striking motion us used to destroy or break the bone or muscles of vital spots with the least twist of the attacking tool. The pressing and breaking motions are illustradted in the self-defense techniques of the Encyclopedia.
The attack is named in accordance to the relative position of the attacking tool; the angle facing the target, the method of attack and the stance taken. For exercise purposes, each target position (e.g. high, middle, low) corresponds to that of the attacker’s position.
The basic principles are:
1. Jerk the hip and abdomen throughout the action, slowly at the beginning and sharply at the moment of impact. The hip is jerked slightly before the action in order to concentrate the larger muscles of the hip and abdomen together with the smaller muscles of the four extremities against the target simultaneously.
2. Completely twist the attacking tool, with few exceptions, in order to use full acceleration especially in punch techniques.
3. Tense the abdomen at the moment of impact by exhaling sharply.
4. The moment the attacking tool reaches the target, pull it back to allow it to be ready for the next action while preventing a grab by the opponent.
5. The attacking tool usually will form a triangle with the shoulders at the moment of impact when attacking the opponent in the front.
6. Hold the breath while attacking or blocking.
