Hai Bo examines the mass social transition from the idealism of the Cultural Revolution (1966–76) to the pragmatism of everyday life of the 1990s. The artist uses studio portraits made during the Cultural Revolution and juxtaposes them with portraits of the same sitters photographed around the end of the twentieth century. Expressing this period of sweeping social change that touched the lives of more than one billion Chinese people, Hai Bo charts the ageing process and the inexorable march of time.
