Abstract: Pan Daogen, a Confucian doctor in Kunshan in the late Qing Dynasty, made detailed records of the writing activities during the Daoguang and Xianfeng periods in his diary. These records involved the transcription and circulation of many manuscripts and transcripts of Chinese medical books. It can be found that Pan Daogen's medical book transcription activities, as a daily academic practice, were an integral part of reading, marking, proofreading, annotations, prefaces and postscripts. Through a certain social network, medical books were shared to form a group of mutual transcription. The transmission, transcription and proofreading of medical books promoted academic exchanges and debates in a certain space field, forming a common academic topic, which was one of the factor promoting the prosperity of regional medicine.
