Mao Zedong pointed out that socialist contradictions can be divided into contradictions between ourselves and the enemy and contradictions among the people, which are based on the fundamental unity of people's interests, so they are non-confrontational contradictions. Contradictions between the enemy and ourselves are antagonistic and should be resolved by dictatorship and contradictions among the people by democracy.

The main contradiction in our country is already the contradiction between the people's demand for the establishment of an advanced industrial country and the reality of a backward agricultural country, and the contradiction between the people's demand for the rapid development of economy and culture and the current situation that economy and culture cannot meet people's needs.

In front of us are two completely different social contradictions, namely, the contradiction between ourselves and the enemy and the contradiction among the people. For contradictions among the people in the political and ideological fields, we should implement the principle of "unity-criticism-unity" and adhere to the methods of persuasion, education and discussion.

Contradictions among the people in material interests and distribution should be balanced and properly arranged, taking into account the interests of the state, the collective and the individual; Regarding the contradiction between the people and government organs, we should adhere to the principle of democratic centralism, strive to overcome the bureaucracy of government organs, and strengthen ideological education for the masses.
