Bo Yibo
Putting forward the "Seeking truth from facts" principle, the plenum started the repudiation of the Cultural Revolution: the "Counterattack the Right-Deviationist Reversal-of-Verdicts Trend" campaign aimed against Deng was openly rejected, and Peng Dehuai, Tao Zhu, Bo Yibo and Yang Shangkun were rehabilitated. The Cultural Revolution was openly rejected only in 1981 at the Sixth Plenary Session. The weakness of both the National People's Congress and the Supreme People's Court during this period were criticized as well.
