Under the influence of Leninism，Mao Zedong applies Marxism to analyze Chinese national characteristics and realistic situation and forms the theoretical premise of Marxism's popularization. He also regards the masses as the main force of Marxism's popularization under the guidance of people-oriented thought. He attaches great importance to ensuring and meeting people's various economical，political and cultural needs and provides the driving force for Marxism's popularization. He uses a variety of channels，such as schools，newspapers and periodicals and constructs the multiple transmission routes of Marxism's popularization by means of self-education and academic research.
