《明史·列传·卷二百零八》
该国北部与契丹为邻，西部靠近女真，其南部是日本。元朝至元中年，西京归附元朝，朝廷在该地设置东宁路总管府，以慈岭的尽头与朝鲜为界。
其国北邻契丹，西则女直，南曰日本，元至元中，西京内属，置东宁路总管府，尽慈岭为界。
The country’s north borders on Khitan, the west borders on Jurchen, and the south is Japan. Among the years in the Yuan dynasty’s Zhiyuan reign, Xijing pledged allegiance to the Yuan dynasty, and the imperial court set up the Dongning Lu headquarters in that location, with Ciling as the boundary with Korea.
