Dialectical materialism is the worldview and methodology of Chinese Communists. Mao Zedong once said that Marxism consists of several branches of learning, but the foundation is Marxist philosophy.In his works produced during the years of the revolutionary war such as Oppose Book Worship, On Practice, and On Contradiction,and in those from the period of socialist construction including On the Ten Major Relationships and On the Correct Handling of Contradictions Among the People, Mao cleverly applied the worldview and methodology of dialectical materialism, gave distinctive Chinese characteristics to Marxist philosophy, and set a shining example for our Party in grasping and applying dialectical materialism.
