The Communist Manifesto reveals that the core idea of the communists is the elimination of private ownership, specifies that the driving force of class society development is class struggle and its important role in socio‐historical development, and elaborates that the ultimate value of the proletariat is the free and comprehensive development of man and constructs the ideal social goal for which mankind strives. The Communist Party of China has always adhered to these three major assertions and applied them flexibly, further strengthening the people‐centred development ideology by analysing the main contradictions of socialist society with Chinese characteristics in the new era and arguing for the necessity and inevitability of building a community of human destiny, enriching the theoretical system of socialism with Chinese characteristics.
