No that school appears to be in Korea maybe?
but based on the background is that China, Taiwan or someplace else in the East?
If it's the one I think it is (can't see it on Youtube), it's a mantis school in Korea. I think I remember seeing it was either Taiji Meihua or Taiji mantis. Couple guys hitting hard & fast in drills??
I think Tai Chi is very much kung fu or at least true kung fu and tai chi should share many fighting principles. Kung Fu without the "softness" is not CMA in my opinion. Sorry if I offend.
Also, here is a clip we have had discussions on allready, but represents what I consider good kung fu. Its not free sparring and lacks a little of the elements we try to train, but its pretty dang good. (Turn your sound down)
