魯平
On 25 May 1966, Nie put up a big-character poster on the campus of Peking University. The poster criticised Song Shuo, deputy director of the Beijing Municipal University Bureau, Lu Ping, the President of Peking University and head of its Party committee, and Peng Peiyun, an official in the Beijing Municipal University Bureau. Although Nie's main criticism was over the control of Peking University by the bourgeoisie, the aim of the campaign was to legitimise the purge of the Beijing municipal party chief Peng Zhen, by exposing his alleged crime of supporting a bourgeoise reactionary education line. This was pushed by members of the radical clique surrounding Mao Zedong, including Kang Sheng and his wife Cao Yi'ou.
