The concept of People varies in content in different countries and and in different periods of history in a given country... During the Japanese war all classes and social groups opposing the Japanese invasion were People; Chinese collaborators with the Japanese were the Enemy. During the war of liberation, US imperialists and their running dogs were the Enemy, those opposed to them were the People. In the present stage the social groups which favour the cause of socialist construction are the People, and those who resist are the Enemy.

--Mao Zedong
