Marxist theory is a social and historical theory with the ultimate goal of human liberation. It not only reveals the law of the development of human society and the

root cause of the existing problems in the real society with historical reflection and criticism, but also insists on the criticism of weapons to change the real world in order to realize human liberation. Therefore, as soon as Marxism was born, it brought about changes in real social life with its revolutionary and critical nature, and profoundly influenced and changed the world historical process of the 20th century. Therefore, the study of Marxist theory in the new era needs to combine the study of social history with that of ideological history, so as to realize the organic unity of the theoretical logic of ideological development and the historical logic of social changes in reality, so as to clarify the current historical situation of human society through historical reflection, and provide possible directions for the future history of human society from the theoretical perspective.
