Lu Ping
After the purge of Peng Zhen, the Beijing Party Committee had effectively ceased to function, paving the way for disorder in the capital. On May 25, under the guidance of —wife of Maoist henchman Kang Sheng—Nie Yuanzi, a philosophy lecturer at Peking University, authored a big-character poster () along with other leftists and posted it to a public bulletin. Nie attacked the university's party administration and its leader Lu Ping. Nie insinuated that the university leadership, much like Peng Zhen, were trying to contain revolutionary fervour in a "sinister" attempt to oppose the party and advance revisionism.
