Du Yi is an author about whom limited public information is available; his nationality, dates of birth and death, and personal background cannot be confirmed from the existing records. Judging from the two works held in the collection, his writing and compilation span two quite different fields—computer technology and literature—a rather unusual range of subjects. Among them, MySQL Database Application Technology and Practice is a general computer-science title that focuses on the application and hands-on use of database technology for learners who need to master this tool, while Ancient Forms, Modern Style belongs to modern poetry and, as the title suggests, appears to seek a fusion of classical poetic forms with contemporary sensibility. One work leans toward technical practice, the other toward literary expression, indicating that the author's interests are not confined to a single category. With little further public material available, his life and creative development cannot be traced in more detail, and readers may form a general impression of him through these two works.
