Ten Chinese PhD students are demanding that Beijing Normal University Professor Yu Dan be away from her television show on CCTV10. They argue that her on-air explanations of Confucius’s Analects (孔子《论语》) are “incorrect and misleading”. Yu is known for explaining Confucius’s Analects to a TV audience. But some complain that her explanations are unfaithful to Chinese tradition. But Yu doesn’t seem to worry too much about her critics, saying, “It’s a matter of personal choice. Some like KFC, while others like McDonalds.” |

STEALING some online gamer’s password might seem less harmful than credit card theft. It does keep the victim from wearing himself out all night playing. But it is not all that nice, says 19-year-old Zhang Qiwen, in Shanghai. Last August, Zhang accidentally downloaded a Trojan while playing Warcraft. The Trojan is a type of virus used by hackers to steal people’s passwords. Overnight the Trojan transferred all the “gold” (game credits) from Zhang’s private account to an unknown account. Zhang hopes the police will find and punish the thief, who can also pocket some cash since the stolen “gold” can go on sale online. |
