Abstract: The development history of the Communist Party of China is a history of struggle that leads people to pursue a happy life， which has gone through four stages: “independence”， “hard work”， “common prosperity” and “better life”. Under the specific conditions of the times， on the one hand， each stage is sublated in the latter stage， thus forming the internal link of the people's happiness view of the Communist Party of China. On the other hand， each stage includes several previous links within itself， thus forming the whole of the people's happiness view of the Communist Party of China. Thus， these different stages of the concept of happiness constitute a growing organic whole， in which “independence” is a prerequisite for people's happiness， “hard work” is the realization path， “common prosperity” is the material basis， and “better life” is the goal. From a new historical perspective， we must accurately grasp the new demands of Chinese people in terms of independence， hard work and common prosperity， and continue to realize the people's aspirations for better life.

Key words: the Communist Party of China; people's happiness view; independence; hard work; common prosperity; better life
