契丹
Qidan Guo Zhi ("Records of the Khitan State") is a 13th-century Chinese book chronicling the history of the Liao dynasty (916–1125) and the Khitan people. It was written by Ye Longli of the Southern Song dynasty, probably published 1265–1274 during Emperor Duzong's reign, even though the preface claimed it was submitted to the throne in 1180. (Ye Longli did not pass the imperial examination until 1247.)
