Xu Bo is an author from ancient China about whom very little is known. Available public information is limited: his native place, dates of birth and death, and official career cannot be reliably established, and no commonly accepted English form of his name exists. What can be confirmed is that a work titled Xu Bo's Treatise on Lychees is attributed to him and has come down to us; it is classified under culture. The book concerns the lychee, a famous fruit of the Lingnan region, and belongs to the traditional genre of specialized treatises. It presumably covers varieties, producing areas, morphological features, cultivation, and tasting, combining botanical record with a literary style. Treatises on lychees have been written since the Song dynasty, often by authors familiar with southern local conditions, and they hold value both for agricultural reference and for food culture. Although Xu Bo's work may not rival the reach and influence of famous treatises, it offers a concrete sample of ancient lychee knowledge and related cultural interests, and is useful for the study of traditional plant monographs and local produce. Because historical sources are scattered and lost, further research on Xu Bo himself is still needed.
