Adhering to the people first embodies the fundamental requirements of historical materialism for world outlook and methodology, such as the theory of people's subjectivity, the theory of people's creation, the theory of people's value, and the theory of mass viewpoint. Adhering to the people's supremacy in practice requires us to stand firm on the people's stand, grasp their wishes, respect their creativity, concentrate their wisdom, safeguard their interests, realize their enjoyment, and always take it as our goal to continuously satisfy their yearning for a better life.
