Doesn't the hosting nation get to demonstrate a sport that's not part of the Olympics? Isn't that how Tae Kwon Do got put in, because of Seoul Olympics? Could be wrong though, never really watched the Olympics since none of the channels would show TKD or Judo.
I think you meant Bagua. It can be Bagua, Pagua, Pakwa, and even Bat Kwa. But I've never seen it phoneticized as Pau Qau. It doesn't sound right in either Cantonese or Mandarin.
