Yes. I have tried it, but I wasn't very good at it. The moves look so beautiful and fluid, but when I did it, it wasn't that pretty. The instructor was always adjusting my arms for me. I just didn't get it. I have watched Chinese people doing it and it does look beautiful. I am not sure how it is a martial art. It looks too beautiful and graceful to be used for self defence.
I've thought about doing it as it looks so calming. I've seen small groups of Asian people doing it as well as single people and I do enjoy watching them in slow motion but don't think I'd ever be as graceful as they are.
