"Parallel to these two revolutions and with a view to effectively serving them, we carry out an ideological and cultural revolution. In the field of ideology, we must foster and strengthen proletarian ideology, fight all forms of bourgeois ideology, criticize petty-bourgeois ideology and continue to do away with all vestiges of feudal and other erroneous ideologies. In the field of culture, we inherit in a critical way the national culture, and build for Vietnam a new culture, socialist in content and national in character."
January 1, 1970
