after losing the match in the semi-final round. wang chen had finally waived her match against zhu ling at first set. she met the press shortly afterwards and claimed that those umpires had a bias against her. she just can't play the game any longer and will never participate in the chinese national championships again in the future. imo. "biased umpires" is one thing. anyway, she should take the pain, finish the game and show them/us the true sportsmanship!
