Zeng Anzhi's life is very sparsely documented in publicly available sources; his nationality, dates of birth and death, and English name are not clearly recorded. What can be confirmed is that he is the author of one work, He Pu (A Register of Grain), which is classified in some library catalogues under literary appreciation. The title He Pu suggests a register-style account of rice plants, farming, or related subjects, and the pu (register) genre itself combines systematic record-keeping with literary description, which may explain its placement in the literary appreciation category. From the available evidence, Zeng Anzhi's writing appears to emphasize close observation and orderly arrangement of concrete subjects, presenting knowledge of names and things in a concise, well-organized manner that is both practical and readable. Because only one work survives and related historical materials are scarce, his biography, social connections, and overall literary output remain difficult to examine in detail; readers and researchers should exercise caution when citing him and should focus on the subject matter and stylistic features of He Pu.
