"Every academic in China works under a censorship and ideological regime that distorts and repackages his work to make China appear like a normal and free society. …Offending phrases or topics may lead to sanctions such as failing an “ethical evaluation.” Party leaders in China’s universities also make use of student informants who report any politically banned speech from their professors in the classroom. The system generates a constant rumor mill about topics that are off-limits, and also has the consequence of denying China’s rulers useful information about governance issues like corruption."
