Bu Shi is an ancient Chinese author associated with animal husbandry, and the only work attributed to him in the existing records is The Method of Raising Sheep (Yang Yang Fa). Publicly available information about his native place, dates of birth and death, identity, and life events is very limited, and the present collection contains no supplementary records that could fill these gaps, so it is difficult to sketch a complete picture of his life. Judging from the surviving work, his writing centers on practical experience in raising sheep and belongs to the category of practical livestock techniques; the text likely emphasizes operational methods and routine management and bears the distinct character of summarized experience. Such content was often included in ancient Chinese works on agriculture and sericulture, reflecting the author's familiarity with practical farming. It should be noted that the present collection classifies this book under literary appreciation, a category that clearly diverges from the subject matter, so readers should judge for themselves in light of the original text. Overall, Bu Shi's significance lies mainly in the livestock knowledge preserved in The Method of Raising Sheep.
