Cultural transformation is central to class formation. By culture，which in this paper is related to “worker’s cultural palace”，a particular materialized cultural space for urban working-class being built across the Mao era，we understand the distinctive ways of expressing，articulating，and reproducing everyday life that are essential to the class identity and class consciousness of China’s working-class. This paper analyzes worker’s cultural palaces built in the 20th Century，with examinations of the physical space，the transformative history from Maoist to Reform and opening up era，and the workers cultural practices therein. Empirical data are gathered through repeated site visits，interviews with palace staffs，participant observation in workers’ cultural group activities，and documentary. Theoretically，this paper tries to develop a more refined historical-comparative framework，which offers a revision for the theoretical articulation among cultural space，socialistic industrialization，and class formation in China.
