Abstract:The “all-for-people” thought is the foundation of CPC's mass line. In different periods, it has different expressions. MAO Ze-dong required us to serve the people whole-heartedly. DENG Xiao-ping advocated common prosperity. And JIANG Ze-min held that CPC is the representative of people's benefits. In HU Jin-tao' time, CPC put people in the first place. And now, XI Jin-ping has pointed out that we depend on people to bring Chinese dream into reality. Though different leaders of CPC have different expressions in terms of the “all-for-people” issue, their nucleus is that we strive to meet people's demands for materials and culture through development of productive force, hence realize the fundamental interests of most people. Further, we have to be able to manage to solve the problem of people's existence, development rights and interests, arouse people's enthusiasm and get them into the socialist construction with Chinese character. In this way, we can bring the great Chinese dream of national rejuvenation into reality.
