Top universities face exams for corruption

Institutes hit by allegations as education leaders resign, report Tang Yue and He Na in Beijing.

Three years ago, Renmin University of China made national headlines when it became the first college in the country to offer a master's degree in anti-corruption studies.

Last month, the university was in the news again, but for less welcome reasons. Cai Rong-sheng, head of student admissions at Renmin - one of China's most prestigious educational establishments - was detained as he attempted to flee the country.
