Th is paper is part of a larger project to explore the genealogies of cosmopolitanism in the emergence of mass culture in postwar Hong Kong. Th e sociological and intellectual roots of a mass cosmopolitan culture in the 1970s and 80s represent signifi cant phenomena in their own right. In this context, the history of City Magazine (haowai) and its underlying mentalité that has made it a representative voice of Hong Kong's urban youth culture is worth attention. In its thirty years of publication, it has refl ected in sophisticated ways the ongoing evolution of a forward-looking, youth-oriented and trendy popular culture that eventually became the staple of Hong Kong life. What was its role in promoting the advent of such culture?
