This work comprises three separate contributions in ink on paper: a preface by Wu Zhiying and He Jiaqi on two leaves, and a colophon by He Fanpu on one leaf. The piece exemplifies the Chinese scholarly tradition of collaborative documentation, wherein multiple accomplished individuals contributed their calligraphy and commentary to a shared work. Such compilations of prefaces and colophons were common in classical Chinese art and literature, serving to authenticate, contextualize, and honor the primary work they accompanied.
