Abstract: Chen Yan, also known as Chen Shiyi, he is a famous engraver in the late Qing Dynasty and the Republic of China. He engraved the writings of himself and his family in the name of “Shiyishi”, known as woodblock in the Shiyishi. The paper classifies and analyzes the types and contents of the published and extant documents of Chen Yan’s Shiyishi, compares them with Chen Yan’s Shiyishi engravings collected in the library of Sanming University, and sorts out the differences and analyzes the reasons. The engravings of Chen Yan’s Shiyishi make up for the lack of existing documents. It is the original physical archive material that supplements and improves the existing Shiyishi Series catalogue and the catalogue of woodblock in the Shiyishi. It also adds new content to Chen Yan’s literature and related research. It is extremely difficult to inherit so far, and its cultural relic value is self-evident.
