Duan Gonglu was an author of the Tang dynasty. His life is unknown, and his native place and dates of birth and death cannot be confirmed; public information about him is limited. Only one work by him, Beihu Lu, survives. It is a notebook-style work recording observations of local conditions and customs in the Lingnan region. Its contents chiefly concern local products, folk customs, food and drink, and plants, trees, insects, and fish. The writing is closer to casual jottings, with short entries that emphasize faithful recording of what was seen and heard, and it has a clear regional flavor and a natural-history character. Works of this kind formed a distinct strand among Tang notebooks and provide later readers with reference material for understanding social life and natural products in Lingnan at the time. Because few details of the author's own life have been transmitted, his name is generally known through Beihu Lu, and scholarship usually starts from the text of that book when discussing its historical value and descriptive features.
