Teng Zhu: publicly available information about this author is limited. Basic biographical details such as nationality, dates of birth and death, and educational background are not clearly recorded, so little can be said about his life. Within the library's holdings, only one work appears under his name, A Glance at America (Meiguo yi pie), which is classified under world history; this suggests an interest in foreign history and observations of other countries. On the basis of the available evidence, it can be confirmed that he enters the view of Chinese readers through this single work, which offers a general survey-style introduction to American society and belongs to the broader tradition of writing about foreign lands within world history. Because further historical sources are lacking, it is difficult to judge the full range of his writing style or his later influence; readers seeking a deeper understanding must still rely on the narrative of the book itself to grasp his observational perspective and prose characteristics.
