Abstract:     Historians have long considered the pseudo-Sun Jiagan Memorial case as one of the most important literary inquisition cases. This paper investigates the ways in which the pseudo-drafts were circulated in the society when the Qing dynasty was approaching its most prosperous times. Merchants from a variety of social strata served as the main distributors in the circulation of the pseudo-drafts. They acquired information through the guilds in the commercial centers and further disseminated the drafts to a wide range of locales. At the same time, commoners in the local society expressed their discontent with the Qing rule and displayed their political and cultural mentality through spreading the pseudo-drafts. The commercial information circulation weakened the state power，rendering the seemingly powerful and efficient provincial governors incompetent in their investigation of the pseudo-drafts case, and the emperor could not do anything to help.
