Yang Shi's biographical information is limited in publicly available sources: his nationality, dates of birth and death, and English name are not clearly recorded. Only one work of his is confirmed in the collection, Yang Shi's Remarks on Poetry (Yang Shi Shihua). Judged by its common classification, the work is placed under Eastern philosophy, suggesting that its content is not merely poetic criticism but may also involve discussions of poetic creation, aesthetic ideas, and even broader philosophical thought. The shihua, or remarks on poetry, is a traditional Chinese genre that combines literary criticism with intellectual reflection, often developed in the form of notes and informal discussions, concise in language yet rich in implication. Through this form, Yang Shi links poetic thinking with philosophical concerns, giving the work a speculative dimension beyond the evaluation of poetry and art. Because biographical materials are scarce, present-day understanding of his overall output remains quite limited, yet Yang Shi's Remarks on Poetry, as the one surviving text available here, offers a direct clue to his poetic interests and intellectual orientation and deserves attention from readers interested in Eastern philosophy and classical poetics.
