An acclaimed scholar of the Qianlong and Jiaqing periods, Weng Fanggang (1733-1818) was celebrated for his achievements in epigraphy, painting, calligraphy, and literature. Weng was particularly renowned for his mastery of calligraphy. His scholarship in Confucian classics was also outstanding, differing from that of his contemporaries, which boasted philological and evidential findings. He addressed larger issues, concerning the problems faced by the country. In his self-edited Wengshi jiamen lüeji, Weng gives accounts of his life, deeds, and writings. Based on this book and other prefaces, postscripts, notes, and calligraphies by Weng, as well as Weng's Fuchuzhai shiwenji (in manuscript form, now in the holdings of Taipei's National Library), Shen Jin recently published Weng Fanggang nianpu (The Chronological Biography of Weng Fanggang). It is a result of close to four decades of research and labor, a truly impressive scholarly work that contributes greatly to our knowledge of Weng's life and works. Given the size of Weng's own writings and the range of materials that Shen drew on, there are bound to be lacunae or errors in the Chronological Biography. For example, materials and information from Weng Fanggang tiba shouzha jilu-a collection of Weng's prefaces, postscripts, notes, and letters, also edited by Shen-are not entirely incorporated into the Chronological Biography. As an aid to Shen's readers, my paper supplements or corrects about 250 dates or facts that are recorded in Weng Fanggang tiba shouzha jilu, but are missing or mistaken in the Chronological Biography.
