Abstract: From the perspective of the Chinese Communist Party history, over the past century, the Communist Party of China  in the new era has led way forward a new height and opened up a new realm, whether in terms of historical experience and its ability to govern, or in terms of adapting Marxism to the Chinese context and the needs of our times and initiating and advancing the great project of Party building. From the perspective of the history of the New China, development is the theme of Chinas economic and social development. After ten years of development in the new era, China has ascended to the ranks of and took the lead in the worlds modernized countries in terms of its composite national strength, economic strength, and scientific and technological capabilities, as well as its per capita GDP, the structure of the three industries, and the universal access to education. The national rejuvenation has entered an irreversible historical process. From the perspective of the history of reform and opening up, institutional innovation is the cornerstone of socialism with Chinese characteristics. After ten years of reform in the new era, the system of socialism with Chinese characteristics has become more mature and welldefined, which provides the most fundamental and stable guarantee for national rejuvenation. From the perspective of the history of socialism, socialism with Chinese characteristics for the new era has demonstrated to the world with the vigorous development of the socialist causes that socialism has not failed China and China has not failed socialism. From the perspective of the history of the development of the Chinese nation, a moderately prosperous society has been built in all respects in the new era. The Chinese nation has made a historic leap from standing up, getting rich to getting strong, the Chinesestyle modernization has created a new form of human civilization, and the goal of the great rejuvenation of the Chinese nation has never been as clear as it is today.
