Am I the only one to spot the glowing cowardice presented by this not so open, open challenge. By not allowing sanda people to issue challenge, Xu is effectively, and knowingly, eliminating the chances of him being challenges by a traditional Chinese fighter that trains to fight.

Heads up to Xu, traditional Chinese fighters will ALSO be sanda guys more often than not. Sands is a platform traditionalists use to develop their skills.

Basically I see his challenge like this:

MMA fighter opens issue challenge to all non fighter sport artists. By specifically excluding traditional fighters he's creating his own odds.

I know this guy that just got out of prison last year. he served his years for deadly assault. Got in plenty of fights in prison and benches near 600. Hes a fewcking animal he has no pro record but he also makes xu look like a midget. If he takes some tai chi classes will xu fly him to China for a possible mauling? Or will he give another excuse to avoid people he fears may beat him?
