Xu Guangqi was an important scholar and official of Ming-dynasty China. Publicly available details such as his exact birth and death years and native place are limited here, so no conjecture is made. The book database currently holds two works under his name, both centered on the Nongzheng Quanshu (Complete Treatise on Agriculture), including the original text and an edition without annotations, which shows that his writing focused on agronomy and practical knowledge. In subject matter he attends to agricultural production, water conservancy and land systems, and the livelihood economy; his style aims at practical usefulness and shows a clear orientation toward statecraft and concrete application rather than empty metaphysical discussion. This manner of writing gives the works the character of both compilations of material and operational guides, and they have had a lasting influence on later agricultural compendia and the spread of farming techniques. Their classification in the database as classic works also indicates their enduring reference value within traditional knowledge.
