Gongguo ge (ledgers of merit and demerit) emerged in the late Ming and Qing dynasties as a way to convey group ethics, and to make legible the processes of retribution. Able to be tailored to different traditions, the growth in their popularity and influence have been attributed to the rise of print culture and the acceptance of mercantile perspectives; ledgers are early examples both of mass media and the quantification of self. Drawing on scholarship on contemporary self-tracking, and attending to the visual formats of gongguo ge, I will argue that they represented a new technology of self-reflection that constituted particular kinds of social and moral persons. The practices instantiated by the ledgers made them especially important for moral pedagogy, and the persons constructed through the use of the ledgers are both quantified and ritualized. The varied visual formats of the ledgers shaped different understandings of role of ritualized self-reflection. Some ledgers have incorporated ritual within the list of behaviors for self-assessment, but also the very act of monitoring and quantifying certain types of action aligned gongguo ge with longstanding notions of everyday life as patterned through ritual. Finally, a discussion of more recent examples of the use of ledgers will show how they continue to respond to new technologies of information management and self-quantification.
