Longsha jilüe 龍沙紀略

Longsha jilüe 龍沙紀略 is a book on northeast China written during the early Qing period 清 (1644-1911) by Fang Shiji 方式濟, courtesy name Woyuan 沃園, from Tongcheng 桐城, Anhui. The term Longsha is derived from the biography of Ban Chao 班超 (32-102 CE) in the official dynastic history Houhanshu 後漢書, where it denoted the regions beyond the Chinese empire (saiwai 塞外 "beyond the passes"). In 1711, the author's father Fang Dengyi 方登嶧 was exiled to the northeast because he had insulted the dynasty, and lived for many years in the garrison of Bukui 戍卜魁 (today's Qiqiha'er 齊齊哈爾, Heilongjiang).

The book is the result of Fang Shiji's observations he made when visiting his father. It describes the geography, administration, military, agriculture, customs and habits, food, taxes and tributes, local products and buildings of the region, altogether in nine chapters. It is the earliest surviving reliable report on Heilongjiang, and is in many points a valuable supplement to the official local gazetteer Shengjing tongzhi 盛京通志.

It is included in the series Siku quanshu 四庫全書, Shugutang shiji 述本堂詩集, Jieyueshanfang huichao 借月山房彙抄, Xiaofanghuzhai yudi congchao 小方壺齋輿地叢鈔 and Zhaodai congshu 昭代叢書, as well as the modern series Longjiang sanji 龍江三記 and Heishui congshu 黑水叢書.
