beat down the Taichi guy, the Wing Chun guy and other Kung Fu guys.  He was banned from all major  social media and they see him as their enemy number one.  He is the only person in China who dares to discredit Chinese traditional martial arts, who dares to challenge and accept challenges. His Sanda Kung Fu is just like Muay Thai has no technique for escaping after being mouted on the ground.  He knew it after he lost a fight to that Jujitsu guy.  Brother Xu is not a professional fighter just an amature,average fighter but he has so much courage. He will lose if he fights a professional sanda fighter or muay thai fighter on a stand up-match.
