Lu Ping
Earlier in 1966, Kang Sheng sent his wife, Cao Yi'ou, to Beijing University as part of a team designed to rally leftists against the university president, Lu Ping, and other officials aligned with Peng Zhen. Cao sought out Nie Yuanzi, a Party branch secretary in the Philosophy Department with whom Kang and Cao had become acquainted years earlier in Yan'an. With information from Cao Yi'ou that Lu Ping had lost high-level Party protection, Nie Yuanzi and her leftist allies wrote an infamous big-character poster attacking the university leadership and launching a movement that over the next three months threw Beijing University into chaos.
