The Manifesto of the Communist Party, as a work that symbolizes the birth of Marxism and the rise of the international communist movement, has transformed socialism from utopia to science and from theory to reality. It has completely broken the global landscape of capitalism dominance. The “matters of confidence”put forward by General Secretarv Xi Jinping is an extension of the theory born out of the process of adapting Marxism to the Chinese context.It organically combines the revolutionary ideals of the proletariat in the“Communist Manifesto”with the Chinese Dream to achieve great national rejuvenation. And from the four angles, i.e. path, theory, system and culture, this concept refines the belief of Communists. Therefore. the“matters of confidence”and the Communist Manifesto transcend the value of the times and is still an important basis for the construction of socialist theory by the Chinese Communists.
