In Mao Zedong's 1957 speech "On the Correct Handling of Contradictions Among the People", he comments that "At the present stage, the period of building socialism, the classes, strata and social groups which favour, support and work for the cause of socialist construction all come within the category of the people, while the social forces and groups which resist the socialist revolution and are hostile to or sabotage socialist construction are all "enemies of the people"."
