Abstract:Always insisting on the peoplecentered approach,the 100year history of CPC is the history of struggle to unite and lead the people to realize their yearning for a better life.The historical evolution of the thought of peoplecentered development since the founding of CPC has gone through four stages including the New Democratic Revolution (1921-1949),the Socialist Revolution and Construction (1949-1978),the Reform and Opening up (1978-2012),and the New Era of Socialism with Chinese Characteristics (2012-).We should implement the Mass Line of CPC and mobilize people for production and development; we should insist on the overarching goal of CPC and promote the free and allround development of the people; we should keep in mind the original mission of CPC and the peoplecentered approach.To realize the Second Centennial Goal,insisting on the peoplecentered approach upholds the leadership of CPC and gives full play to the advantages of the socialist system with Chinese characteristics.It helps to improve people’s livelihood and enhance people’s sense of contentment,happiness and security.With the strategy of “Two Overall Situations”,it contributes to the building of a community with a shared future for mankind.
