Fei Ying is an author about whom relatively little public information is currently available: neither nationality, dates of birth and death, nor an English name has been clearly recorded, and only one work can be verified, the social novel The Mountain God. Judging by genre, Fei Ying's writing leans toward social fiction, focusing on the circumstances of individuals and social relations in realistic settings rather than on purely fantastic or entertainment-oriented storytelling. As the representative work, The Mountain God is the main window through which to understand this author's creative profile. Because the existing material is insufficient to reconstruct his life, literary lineage, or stages of writing, this note can only offer a brief account at the level of works and cannot fully discuss his literary roots or social influence. As far as is known, Fei Ying's output is small, making it difficult to judge whether his style has been sustained; readers who wish to learn more about this author should still rely primarily on the text of The Mountain God and supplement it with subsequent public information.
