In 1973, during the Cultural Revolution, Yin joined the Chinese Communist Party, and, four years earlier in 1969, at the suggestion of Jiang Qing, changed his name to Yin Chengzhong (殷诚忠), as his original given name, Chengzong (承宗, literally "carrying on the ancestral legacy"), was considered unsuitable due to its supposed association with the perpetuation of the traditions of the exploiting class; his new given name, Chengzhong (诚忠), carried the literal meaning of "sincere and loyal." (After relocating to the United States in 1983, however, he reverted to his original name.) At a time when virtually all Western art forms were forbidden, Yin passionately and ingeniously found an application of his talent: he created the piano-accompanied version of The Legend of the Red Lantern, one of the Eight model plays, the only plays, operas and ballets which were permitted during the period. Although, musically speaking, there was not much originality[further explanation needed] in the work, it was refreshing for genuine music lovers[like whom?] who were longing to have access to Western music[citation needed]. Another creation attributed to Yin is the now well-known Yellow River Piano Concerto. Yin and other members of a special committee arranged this work in 1969 based on the Yellow River Cantata by Xian Xinghai. In the final movement of the concerto, Yin incorporated the melody The East Is Red. The instruments used, the piano and the orchestra, were all Western, but the music was heavily influenced by Chinese folk melodies.[citation needed]
