Kong Qingdong, an outspoken professor at Peking University, became hot topic again for his rudeness when refusing an interview with a magazine. He rejected the journalist with "f*** your mother", which he posted on his micro blogs on Nov 7, 2011.

His behavior triggered a debate about whether a university should keep a teacher who publicly swore. Students from Peking University told media that they have launched a campaign to demand the school fire Kong. In a letter sent to the principal, they listed Kong's violent and crass speeches. They said that Kong's words surpassed the freedom of speech and breached the ethics of a teacher.
