Karate is not as famous as Japanese martial arts. It originated in the prosperous Tang Dynasty in China and was brought back to Japan by Japanese martial arts communicators for improvement. Originally called "Tang Shou", it was officially renamed as Karate on 1935 because of the relationship between Japanese pronunciation and "Karate".
Karate, as a kind of martial arts, has some characteristics of martial arts, such as cultivating self-cultivation, strengthening physique and cultivating sentiment. Of course, the public should be most concerned about the practical value of self-defense.
Each martial art has its own characteristics and advantages, but personally, Sanda is more suitable as a means of self-defense. On the other hand, Sanda is a direct biography of China, and karate is a martial art that the Japanese came back to teach the people of China after learning from China. There seems to be a suspicion of teaching others how to teach others.
