This might sound a little odd and strange and retarded and whatnot but whenever I change the colour of my tori (eg. different force/relax) the way I play changes. Try it out and try and look at wushu in a different way. When I had pure force on, I noticed I mostly held joints instead of keeping them extended, aha. (I checked replays so yeah lol)
Another couple things I tried was to never contract knees and never contract wrists (you can relax them though ofc), it's different and it's fun.
