Taekwondo's main effort is in the legs, and there are strict requirements for formal competition, while fighting is usually both hands and feet. To tell the truth, the actual combat effect of Taekwondo is really difficult to highlight, and it may take good practice to show it.

Comparatively speaking, China's traditional martial arts, such as Jeet Kune Do, Wing Chun Boxing and Cai Lifo, put more emphasis on actual combat effect, and all parts such as fist, knee, shoulder and elbow can play a role, and the actual combat effect should be said to be more obvious.

Of course, martial arts is for self-defense and fitness, not for fighting. This is the same idea no matter how you practice.

I hope it helps you.
