Little is known about Ling Yuan; public information about this author is very limited, and the name is closely tied to the work Feiyan Waizhuan (An Unofficial Biography of Zhao Feiyan). The book takes as its subject the court story of the sisters Zhao Feiyan and Zhao Hede during the reign of Emperor Cheng of Han, recounting their origins, their entry into the palace, and the rumors of their rivalry for imperial favor. Its style is delicate and its plots intricate, with a marked legendary flavor. In the history of ancient Chinese fiction, Feiyan Waizhuan is often regarded as one of the earlier short narrative works dealing with palace secrets, and it had some influence on the later transmission of related subjects in note-style fiction and drama. Ling Yuan is known to later generations because of this book, yet no verifiable records survive of the author's native place, dates, identity, or the full body of writings. Readers should treat the work as a representative piece of ancient legendary narrative, focusing on its subject matter and narrative style rather than inferring specific details of the author's life from extant materials.
