In the history of Chinese academics, Xu Shen’s Shuowen Jiezi (hereinafter referred to as Shuowen) is known as “the first of its kind in the world” because it has the dual characteristics of explaining the form, sound, and meaning of Chinese characters and the characteristics of theoretical works on philology, both of which are practical. It has not only become a treasure of codex for the compilation of character books and exegesis, but also laid down the basic patterns of traditional philology and biblio-linguistics, with far-reaching influence. Many scholars have researched Shuowen in the past dynasties, resulting in the formation of an independent thematic discipline called Shuowen, also known as Xuxue (許學). According to Ding Fubao (丁福保), Shuowen jiezi Gulin (hereinafter referred to as Gulin) attached to the Yingyong Zhushu Xingshi Lu (引用諸書姓氏錄) statistics, there were as many as 203 people in the Qing Dynasty who studied and wrote Shuowen. In fact, there are many scholars and their achievements that are not included in the statistics. After Gulin, especially in the last 30 years, a lot of new materials of scholars in the Qing Dynasty who studied the Shuowen have been excavated and published. Most of these new materials are dispersed in their original state in different large series, so they are rarely researched and utilized, and their documentary and scholarly value is in urgent need of formal recognition. Based on the preliminary results of the major project of the National Social Science Foundation (21&ZD299) chaired by Li Yunfu (李運富), this article discusses the excavation, collation, and research of new materials on Shuowen in the Qing Dynasty.
