The author applies a textual analysis and case study of two dramatic events in rural migrant children's lives: following their parents to cities and returning to the countryside with volunteers. The author finds (1) early life experience holds special importance by differentiating migrant workers' children into "one-and-a-half generation" migrants and second generation migrants; (2) "migrant workers' children" is not an identity, but rather a status; (3) the status identity of migrant workers' children is not solely determined by social structure, but rather driven by events over time, a social construction and unstable; and (4) status identity has both self-expressive and self-protective functions, which respectively constitute an aggressive identity and reactive identity; the conflict between these two identities is especially apparent in migrant workers' children.
