" The ideological consciousness of people does not transform itself of its own accord. It is wrong to think that a change in the social system and material conditions will inevitably be followed by a change in the ideological consciousness of people, which would mean viewing ideological consciousness as a simple reflection of reality. Although a change in the objective conditions affects the development of the ideological consciousness of people to some extent, the establishment of the socialist system and a growth in material wealth do not mean that people follow the communist idea spontaneously. As exploitation and oppression are abolished and the people's material standards improve, ideological education should be intensified. "
