Before 1956,Mao Zedong’s socialism education thought was embodied in establishing its goal and banner,centering on publicizing to the whole Party and national people the ultimate goal of Chinese revolution,i.e.realization of socialism and even communism.Socialism was taken as the ideal blueprint,slogan and banner to guide the heading of revolution,and the Party united people to conduct the new democratic revolution and socialist revolution under the leadership of the Party,whose understanding of socialism was at the simple image stage of the fundamental Marxism principles of scientific socialism,lacking of profound thought and exploration based on China’s specific realities.After the completion of three major transformations in 1956,the socialist system was established.Thus,how to build socialism is the main content of Mao’s education of socialism.However,Mao in his later years broke way from the ideological line of being practical and realistic,took class struggle as the main content of socialism education thought,and thus committed serious mistakes and fundamentally violated the essence of socialism education.Mao’s socialism education thought has enriched experiences,deserving us to take its referential value and develop it,meanwhile it also contains profound lessons,which needs further reflections.
