Yan Jie: public information is limited, and the author's identity and biographical background remain unclear. Still, the four works held in the collection offer a glimpse of the breadth of Yan Jie's academic interests. On the one hand, Yan Jie is connected with traditional Chinese medicine literature, having edited the materia medica monograph Dedei Bencao and been involved in compiling Zhou Qianchuan's Collected Writings on Formulas, Drugs and Health Preservation, which shows an attention to traditional drug compatibility and health-preserving formulas. On the other hand, the works extend into modern data science: Multiple Imputation of Missing Data: Application Cases and Software Operations indicates knowledge of statistics and practical software use. Medicine and computer science, two apparently distant categories, appear under the same author, suggesting that Yan Jie's writing may span both antiquarian textual editing and data analysis. Owing to the lack of reliable external sources, the author's nationality, education and professional experience cannot be confirmed; the above introduction is based solely on the works in the collection and is offered for readers' reference.
