Taekwondo itself has a complete commercial system. Etiquette cultivates students spiritually in line with modern society, fighting skills are gorgeous and beautiful, and the Dojo is clean and tidy. These are the advantages of Taekwondo. There must be some students who just need fitness. These students try to improve their physical fitness in training, especially some visible movements, such as skipping rope and sit-ups, so that parents can see the effect, and try to use happy teaching method in training methods. On the other hand, some students need to defend themselves in actual combat, so they can't teach Taekwondo according to the Olympic Games. They should teach more practical Taekwondo, including elbow, knee and wrestling. The training method should be heavy and bitter, which is in line with the habit of "hard training" in China. The most important thing is to often provide performances or competitions for students. Once you have a goal, you can stick to it.
