The purpose of this paper is to study the role of Cantonese in the identity reconstruction process of migrant people, and its relationship with symbolic power and cultural hegemony. To aid my analysis, I conducted 22open-ended interviews; most of the subjects were migrant people who came from remote areas. Their experience showed that during their adaptation process, Cantonese works as a symbolic mark to distinguish speakers’ identity and influences their social and economic positions. To some extent, the dominance of Cantonese has played a hegemonic role in this field and brought injustice and inequality to migrant people.
