1978年12月18日至22日召开的党的十一届三中全会,重新确立了马克思主义思想路线、政治路线和组织路线,是建国以来党的历史上具有深远意义的伟大转折,也是新中国历史的伟大转折。所谓伟大转折,“中心点是从以阶级斗争为纲转到以发展生产力为中心,从封闭转到开放,从固守成规转到各方面的改革。”① The Third Plenary Session of the Eleventh Central Committee of the Party from December 18 to December 22, 1978, re-establishing the Marxist line of thought, political line and organization is a great turning point in the party’s history since the founding of the People’s Republic of China and a new turning point. A great turning point in Chinese history. The so-called great turning point is that “the focal point is from the reform that takes the class struggle as the key link and takes the development of productive forces as the center, from closure to opening up and from sticking to conventions.”
