Which is better, Shaolin Wushu or Sanda, Muay Thai or Taekwondo?

It depends on what you want to do. There are very few people who practice Muay Thai and live a long life, but there are quite a few in Shaolin. Sanda is also a young man who is still playing at the age of 50. I have never seen it. Wushu originated from fighting, and Taekwondo was also produced in fighting. It can't be said that the actual combat is weak, but when a martial art develops into a sport, its residual strength is limited. In fact, the four kinds you mentioned are the ones that play hardball. Taekwondo is relatively easy (if you are a professional player, I didn't say anything), at least you can't kick it with "shell" leg guards, so it's safe. Muay Thai, Shaolin Wushu and Sanda just came into contact with me, and they practiced very hard (that is, practicing their shells on themselves). But the formation of combat effectiveness will be stronger (provided that you really practice)
