This is an expanded working conference held by the Central Committee of the Communist Party of China in Beijing (also known as the "7,000 People's Congress"). Mao Zedong delivered an important speech at the meeting. He systematically elaborated on the party's principle of democratic centralism and made self-criticism, emphasizing the need to correctly understand the objective laws of socialist construction. The meeting initially summarized the experience and lessons learned from the "Great Leap Forward" and believed that in addition to the reasons for lack of experience, the fundamental reason for the mistakes we made in our work was that many leading comrades were not modest and prudent enough, violated the traditional style of seeking truth from facts and the mass line, and weakened the principle of democratic centralism in intra-party life, national life and people's life to varying degrees. Before and after the meeting, most of the comrades who were wrongly criticized in the "anti-rightist" movement were screened and rehabilitated. Although the 7,000 National People's Congress failed to completely overcome the leftist guiding ideology that existed within the party, it played a positive role in correcting the mistakes of the "Great Leap Forward" and "anti-rightist", and in mobilizing the whole party to resolutely implement the adjustment-centered "eight-character policy" is an important turning point.
