Abstract: Abstract： As a result of opendoor policies and thirty years of Reform， China has become the “world’s factory” and given rise to a new working class comprised of rural migrant workers. Drawing upon a worker’s narrative and our ethnographic studies in Shenzhen and Dongguan， we focus on the selfidentities， anger， and collective action of the second generation of peasantworkers. The special path of (semi) proletarianization has created the working and living experiences of the second generation of peasantworkers in the cities and yielded their trauma， anger，and a deep sense of unfairness. The change of peasantworkers’identity politics has resulted in a significant change of their disposition and action capacities. Compared with the first generation of peasantworkers，the second generation of peasantworkers are much more sensitive to suffering and injustice. The anxiety and pain experienced by the first generation gradually evolve into the anger and resentment that has conditioned the labor strikes and class actions of the second generation. In this paper，we hope to shed light on how human emotion and suffering can contribute significantly to our understanding of collective resistance or class action. Driven by their anger and their sense of fairness，workers have fought against all types of discursive and structural constraints. And as new class subjects，the second generation of the working class now objects to the unfinished process of proletarianization，the racetothebottom globalproduction strategies，the uprooting experience of the city，and their quasi mingong identity.
