Luo Yuan is an author whose biographical details, official career, and native place are poorly documented in publicly available sources. All that is known from the current records is that one work is preserved under this name, Xin'an Zhi (A Gazetteer of Xin'an), commonly classified under literary appreciation. On the evidence available, Luo Yuan is chiefly known to readers through this work. The title points to Xin'an as its subject, indicating a local gazetteer devoted to a particular region; such works typically combine geographical history, mountains and rivers, local customs, notable figures and anecdotes, and documentary records, and thus possess both historical value and considerable readability as prose. Its descriptions of local scenery and its accounts of people and events often carry literary flavor, so later readers may also treat it as material for literary appreciation. Because information on the author's life is insufficient, his associations, intellectual lineage, and official career cannot be described in detail; readers are advised to approach the text of Xin'an Zhi itself and appreciate its care and style in recording local affairs and preserving regional documents.
