This article examines the evolving category of yellow music in the People’s Republic of China from the Maoist era to the early reform period, with a focus on the reception and regulation of Teresa Teng’s music. It argues that yellow music was not a static or CCP-invented concept, but one that expanded and contracted in response to shifting political climates and ideological campaigns. Drawing on archival documents, official newspapers, and autobiographical accounts, this article explores how the label “yellow” was applied to a wide range of musical styles and examines how this shaped public musical consumption. Instead of framing yellow music listening as an explicit form of resistance, this article highlights how such practices reflected unmet emotional and esthetic needs. The entry and eventual state appropriation of Teng’s music illustrate both the cultural consequences of the Cold War and the CCP’s adaptable approach to cultural governance. Teng’s widespread popularity helped revive suppressed traditions of individual emotion and love in music, and her gradual rehabilitation reveals a negotiated space between official ideology and popular demand. Ultimately, this article sheds light on the dynamic interplay between state control, listener agency, and global influence in socialist and post-socialist China.
