The characteristics of the times in modern China and the contradiction between imperialism and the Chinese nation, feudalism and the masses of the people decided that the people of modern China always faced two major historical tasks: first, seeking national independence and people's liberation; The second is to achieve national prosperity and common prosperity for the people. Of the two major historical tasks, the first one that must be accomplished is to achieve national independence and people's liberation, to oppose the aggression of foreign powers and to get rid of feudal autocracy. This historical task determined that the modern China Revolution was both an anti-imperialist national revolution and an anti-feudal democratic revolution. In order to change the situation of national oppression and people's exploitation, we must first carry out national revolution and democratic revolution, end the semi-colonial and semi-feudal society, solve the problem of superstructure and production relations, create the premise and foundation for large-scale economic construction, open the way for further liberation and development of productive forces, and make it possible for the country to be rich and strong and the people to be rich together.

History shows that the two historical tasks of modern China society are not isolated, but interrelated. The former task clears the obstacles for the latter task and creates the necessary premise; The latter task is the ultimate goal and inevitable requirement of the former task. The Chinese nation mainly completed the former task in modern times and the latter task in modern times. The two major tasks are unified in liberating and developing China's social productive forces.
