In the technical area, General Choi Hong Hi created a wide variety of techniques that can be used in almost any situation. They are based on the following principles

1. All movement should be designed to produce maximum power in accordance with scientific formulas and the principle of kinetic energy;
2. The principles behind the techniques should be so clear that even those ignorant to Taekwon-Do are be able to distinguish correct from incorrect movement;
3. The distance and angle of each movement should be exactly defined in order to achieve more efficient attack and defence.
4. The purpose and method of each movement should be clear and simple, in order to facilitate the teaching and learning process.
5. Rational teaching methods should be developed so that the benefits of Taekwon-Do training may be enjoyed by everyone, young and old, men and women.
6. Correct breathing methods should be devised, enhancing the speed of each movement and reducing fatigue.
7. Attack should be possible against any vital spot on the body and it should be possible to defend against all varieties of attack.
8. Each attacking tool should be clearly defined and soundly based on the structure of the human body.
9. Each movement should be easy to execute, enabling the student to enjoy Taekwon-Do as a sport and recreation;
10. Special consideration should be paid to promoting good health and preventing injuries.
11. Each movement should be harmonious and rhythmical so that Taekwon-Do is aesthetically pleasing;
12. Each movement in a pattern must express the personality and spiritual character of the person it is named after.
