Yang Yi is an author with two works listed in the Chinese book database, namely Sutree and The Son of God, commonly classified under foreign literature. Public information about this author's nationality, dates of birth and death, English name, and other personal background is limited, so no definitive account can currently be given, and an introduction to the author's life must therefore be left aside for now. Judging from the available works, Yang Yi's writing relates to foreign literary subjects, and both books have entered the view of Chinese-language readers through translation or creation, serving as entry points for readers to access the relevant literary works. Because verifiable material is scarce, the full scope of the author's writing, the specific features of the writing style, and the literary influence remain to be supplemented by further information; readers seeking a deeper understanding should rely mainly on these two works and consider subsequent public materials.
