The lyrics of "The East Is Red" idealize Mao Zedong, and Mao's popularization of "The East Is Red" was one of his earliest efforts to promote his image as a perfect hero in Chinese popular culture after the Korean War. In 1956, a political commissar suggested to China's defense minister, Peng Dehuai, that the song be taught to Chinese troops, but Peng opposed Mao's propaganda, saying "That is a personality cult! That is idealism!" Peng's opposition to "The East Is Red", and to Mao's incipient personality cult in general, contributed to Mao purging Peng in 1959. After Peng was purged, Mao accelerated his efforts to build his personality cult, and by 1966 succeeded in having "The East Is Red" sung in place of China's national anthem in an unofficial capacity.
