中华人民共和国的成立，开启了中华民族波澜壮阔新的历史征程，中国共产党走进“改天换地”的历史阶段，新中国史与百年党史相连交织。新中国史的叙事原则、方式、内容，确立了正确把握新中国史焦点问题、准确理解中国共产党人精神谱系的基本立场、观点和方法。新中国史叙事的关键在于如何进行历史分期、如何书写“新时代”、如何坚持唯物史观。理解新中国史的核心在于正确对待新中国发展进程中的曲折失误、正确把握改革开放前后两个时期的关系、正确应对新中国现实实践中的风险挑战。新中国史中铸就的精神是中华民族精神的丰富延展，是伟大建党精神的传承发展，是中国共产党人精神谱系的交织重构。新中国的历史，是社会主义发展完善的历史，是改革开放取得伟大成就的历史，是实现中华民族伟大复兴的历史，是构建人类命运共同体的历史，成就了百年大党的伟大事业。

With the founding of the People's Republic of China (PRC), the Chinese nation has embarked on a magnificent new historical journey. The great history of PRC has entered a new historical stage of "changing the world". The history of PRC is intertwined with the history of the Communist Party of China. The narrative principles, methods and contents of the history of PRC have established the basic positions, viewpoints and methods to correctly grasp the focus of the history of PRC and accurately understand the spiritual pedigree of the Chinese Communists. The key to the narrative of PRC's history lies in how to divide the history stages, how to write about the "new era" and how to adhere to historical materialism. The core of the understanding of the history of PRC lies in correctly dealing with the twists and turns in the development process of PRC, correctly grasping the relationship between the two periods before and after reform and opening up, and correctly dealing with the risks and challenges in the practical practice of PRC. The spirit casted in the history of PRC is the rich extension of the Chinese national spirit, the dissemination and development of the great founding spirit of the Party, and the intertwined reconstruction of the spiritual pedigree of the Chinese Communists. The history of PRC is the history of socialist development and improvement, the history of great achievements in reform and opening up, the history of realizing the great rejuvenation of the Chinese nation, and the history of building a community with a shared future for mankind, as well as the great cause of the centennial great party.
