Is practicing Wushu routines useful for actual combat?

100% useful. Routine is the foundation, how to practice it at ordinary times, and when fighting, you will inadvertently combine your own situation in your mind. While your opponent is still being cheated, you have been repeatedly attacked. There are many ways to deal with it and you are doomed to win. I believe that improvisation will take seconds, and the highest record is to kill seven in one breath. Why, the rhythm of three people together is not as good as that of one person, because they are struggling to find a way out, so they have time. In fact, I'm also afraid that one of them will hit you. As long as one quick hit is effective and accurate, you won't feel it if you hit you directly when your body looks on fire. That was ten years ago. If a single routine is useless, forget the sequence and find a useful solution. At this point, in the state, even if you don't care, you are not ready to be suddenly attacked, and your body and brain will quickly start the corresponding way. When people usually take things, their body movements are natural. This state is instinctive or subconscious, and the brain will soon forget to use it and start it automatically. It goes without saying that subjective consciousness is more important.
