Are Wushu routines useful?

To tell you clearly, the routine is very good and beautiful for people, but it is of little use and unrealistic as actual combat. The basic fighting style is very simple, and it is very difficult to practice. When using, no matter what tricks your opponent plays, you just need to attack according to your rhythm. Bruce Lee doesn't respect this kind of martial arts routine with strong performance, so it is very difficult to fight in reality. Very useful in performance, but of little practical value.
