In 1775, during the process of collecting books for the Siku quanshu project, an empire-wide literary inquisition was imposed on the deceased monk Jinshi Dangui (1614–80). As the curious case of censorship developed, the trials not only diminished a major Cantonese monastic community and an old bannermen family but also inspired several imperially commissioned historiographical projects. Exploring the historical significance of the Dangui case at the nexus of early Qing Buddhist networks, Qing imperial control, and the politics of historical memory, this study unravels a multi-layered story of the posthumous censorship of Monk Dangui. It cross-examines a broad range of sources including imperial archives, gazetteers, biji, personal records, and literary anthologies to reconstruct a remarkable moment in High Qing censorship and to present a history of a displaced Buddhist community during the Ming–Qing transition; both became obscured after the Qianlong reconstruction of the imperial order.
