Abstract: The Communist Manifesto serves as the programmatic document of the proletariat party. The principles, programs and missions it expounds define the governing nature of the Communist Party of China (CPC) and lay the theoretical foundation for the original aspiration of the CPC. From the perspective of theoretical logic, the scientific spirit of the Communist Manifesto has promoted the theoretical understanding of the CPC's original aspiration. From the perspective of historical logic, the CPC has established the true essence of the original aspiration in the process of revising the Party Constitution based on the basic program of the Communist Manifesto. From the perspective of practical logic, the CPC has followed the value principles of the Communist Manifesto, practiced and stayed true to the spirit of the original aspiration in the real world. In the new era, fully grasping and adhering to the Party's original aspiration is of profound theoretical significance and great practical value for advancing the new great project of Party building, solving the problems that hinder the development of people's livelihood, and building a modern socialist country in all respects and a community with a shared future for mankind.
