How did folk songs praising Mao Zedong spread through schools and ensembles?

During the Maoist period, the Chinese government actively promoted folk music as a tool for socialist indoctrination, often "reconstructing" traditional songs to reflect new political ideals. To ensure these messages reached the public, folk songs praising Mao Zedong—such as "Red Is the East" and "Sing in Praise of Chairman Mao"—were formally incorporated into the curricula of primary and advanced schools.1

Beyond the classroom, these songs were disseminated through provincial and national ensembles, which were reorganized into collectives like choruses or folk orchestras to align with socialist aesthetics. These ensembles frequently performed songs in praise of Mao or local industrial accomplishments, often utilizing Western-style arrangements to facilitate their use in public education and mass communication. This state-directed effort, supported by the widespread availability of recordings, ensured that such music became a central component of the cultural landscape, serving to communicate national goals and foster loyalty to the regime.1
