Sun Xingyan (Chinese: 孙星衍; 1753–1818), also known as Yuanru (渊如), was a Confucian scholar and philologist during the Qing dynasty. He was born in Yanghu (now Wujin, Jiangsu). After a brief career as a government official, Sun devoted most of his life to the study of the Confucian classics, their history, and phonology. His most influential work is his commentary on the Modern Script and Old Script Shangshu (Shangshu jinguwen zhushu 尚书今古文注疏), i.e., the Book of Documents. Source: Wikipedia (en)
