Dear colleagues, Hope your week is off to a good start. Please join me in welcoming Yuan-Heng Mao to the SSYCDS Listserv. Below please find Yuan-Heng's self introduction: I am currently a Ph.D. Candidate in the History and East Asian Languages Program at Harvard University. I study the sociocultural history of middle-period China, focusing on the dynamic relations between literati networks and literati culture. My current project investigates the transformation of Jiangxi literati networks from the thirteenth to fifteenth centuries. I received my MA degree in History from National Taiwan University, studying the tensions between the agricultural cycle, the market, and the state's financial schedule throughout the Song dynasty. Yours sincerely, Ya Zuo Secretary, Society for Song, Yuan, and Conquest Dynasties Studies
