Seven don't mentions
From China Digital Space
七不讲 (qī bù jiǎng): seven don't mentions
The phrase “seven don't mentions” originated in a directive allegedly issued by the General Office of the Party's Central Committee to institutes of higher education. The directive, which was leaked on Weibo and subsequently censored, outlined seven topics that professors and lecturers were forbidden to raise with students: universal values, press freedom, civil society, civic rights, historical mistakes by the Communist Party, elite cronyism, and an independent judiciary (普世价值、新闻自由、公民社会、公民权利、党的历史错误、权贵资产阶级、司法独立).
The government has historically sought to contain dissent in institutes of higher education, as student movements such as the Tiananmen Square Protests were sources of major unrest.
