Everytime he is the referee for the game, he calls two quick fouls on Yao within 3-4 min of the game. Everytime he calls the game, Yao has one of the worst games of his career. And it seems that the situation is getting worse. He did all this just because Yao taunted him 3 years ago at the World Championship games against New Zealand? If so, the dude has no business in the league unless he is backed up by the gangs.
That's the lesson for Yao and most fans on this board, don't insult people or bash people, You will get paid sooner or later.
