Existing research on Chinese intellectuals naturalizes the category, which is a social construction whose membership, attributes and political significance stem from state and society interactions. Recounting an urban registration campaign for unemployed intellectuals, this article describes the critical moment in which the Communist Party institutionalized its definition of zhishifenzi and local tensions appeared between officials and intellectuals. Due to high unemployment, state specifications and administrative disorganization, the campaign absorbed former Kuomingtang agents, expelled state employees, non-specialists, housewives, social deviants and legally unqualified individuals into the intellectual category. It reinforced longstanding Communist prejudices that intellectuals were politically, morally and professionally suspicious. The article suggests that research on Chinese intellectuals may break new ground, theoretically and empirically, by focusing upon social practices that reproduce the intellectual category beyond the elite level.
