On the Scientific Connotation of “People First” in the Visual Threshold of Historical Materialism—from the Perspective of the Core Proposition “Everyone's Free Development” of the Communist Manifesto

“People first” is the practice and development of Marx's thought of "everyone's free development", and is the latest crystallization of Marxism's Chinese modernization. "Everyone's free development" runs through Marx's historical materialism and deeply reveals the internal contradiction of capital logic, aiming at establishing a real community through communist practice, and then realizing the free development of real individuals. "People first" is characterized by practicality, historicity and transcendence, which demonstrates the essence and innovative spirit of historical materialism. To deeply study the rich connotation and theoretical value of "people first" is of great significance for understanding the world outlook and methodology in XI Jinping's Thought on socialism with Chinese characteristics for a New Era.
