Professor sues Baidu for distress over online posts

Cai Jiming, humanities and social sciences professor at Tsinghua University, is suing China's biggest Internet search company, Baidu, for the personal abuse posted by netizens on the company's forum.

The case opened in Haidian District People's Court on Thursday morning.

Cai, 54, was one of the leading figures behind the holiday reform in 2007, in which the original 7-day May Day holiday was replaced with separate traditional holidays.
