Trying to distance from the
Cultural Revolution practice which put politics before the economy, the third plenary session argued that extensive criticism campaigns against
Lin Biao and the Gang of Four were to be abandoned in favour of a greater attention to economics. The "
Four Modernizations" of industry, agriculture, national defence and science-technology were considered the Party's key tasks for the new period. Former
President Liu Shaoqi's theory that under
socialism, mass
class struggle came to an end, and it was necessary to develop relations of production in order to follow the growth of social forces, was openly endorsed, while Mao's theory of continued revolution under socialism was abandoned. Changes in economic management were called for. The new slogan was to "make China a modern, powerful socialist country before the end of this century". Deng's speech
Emancipate the Mind, Seek Truth from Facts, and Unite as One in Looking to the Future emphasized the need for major reform to implement the Four Modernizations. Although it did not take any open resolution against Mao, the plenary session attacked his leadership, implying that it did not guarantee full
democracy or
collective leadership. Particularly, it criticized the use of issuing Mao's "instructions", as it was said that ''"No personal view by a Party member in a position of responsibility, including leading comrades of the Central Committee, is to be called an 'instruction.'"'' It also put an end to the extensive
personality cult towards Mao and Hua, even going as far as to avoid using the titles "Chairman Mao" and "Chairman Hua". 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. ==Leadership changes==
