Over the three decades since the reform and opening-up, particularly since the 1990s, China’s social fabric has undergone profound transformation. Diverse interest groups and social strata have emerged, evolving from the original triad of workers, peasants, and intellectuals into multilayered strata distinguished by diverging economic interests, political aspirations, social attitudes, and psychological identities. Concurrently, with the relaxation of the household registration system and the emergence of free-flowing resources and spaces, significant population shifts have occurred: geographically—from hinterlands to coastal regions, smaller cities to metropolises, and rural areas to urban centers; socially—from agricultural laborers to industrial workers, blue-collar to white-collar professions, junior to senior managers, and employees to entrepreneurs and employers. This unprecedented social stratification and mobility within merely three decades represents a metamorphosis more rapid and extensive than any other society in modern history. Such transformation epitomizes the direct consequences of China’s economic restructuring, marks a pivotal indicator of socioeconomic transition, and manifests the enduring dynamism of Chinese society.
