It is unfortunate but there is a slightly different concept of what is and is not ethical in China.

China has a number of contradictions. For example, there are many stories of historical and literary heroes standing up for the weak, the poor, the nation as a whole, etc.. Yue Feh is one example. So, there is this ideal of one should be a hero like Yue Feh... Yet at the same time, there is the very common saying about standing up and out "The nail that stands up gets beaten down" that compared to the hero idea can make one totally bipolar.

Similarly, there is the idea that you should be honest.... and smart. Yet if you get cheated by a professional con man who cheats the best of 'em, you are talked about as being "stupid - Gan Do"

So, should we be surprised that in Chinese Competitions, they go to great lengths to have certified and qualified judges. Yet at the same time, the different colleges for wushu send judges from their school...and it is understood that if the beginner judge does not score in favor of their home team, they probably won't get the chance again.

So, we take that idea of "look the other way" and built in retribution and expand the sport out of China...and big surprise...it works the same way.

Shouldn't...but it DOES.

As for Sanshou's problem in the US started with politics. The Boxing Commission and licensing issues have been a plague since 1995 in Baltimore.... So, the possibility of building a sport that has no way of getting going unless those interested in competition obtain a license and the ones putting on an event are licensed with quite often corrupt Boxing Commissions...and then the required insurance...

Well, let's just say Custer had a better chance at the Little Big Horn than Sanshou did of taking hold.
