《水经注·卷十三》
这里就是周武王封给召公的诸侯国。秦始皇二十三年灭了燕国，设立广阳郡；汉高祖把这地方封给卢给，号为燕王，改名为燕国；王莽时改为广有，县名叫代戎。
武王封召公之故国也，秦始皇二十三年灭燕，以为广阳郡，汉高帝以封卢绾为燕王，更名燕国，王莽改曰广有，县曰代戎。
This is the fiefdom that King Wu of Zhou gave to Duke Shao. In the twenty-third year of Emperor Qin Shi Huang's reign, the state of Yan was destroyed and Guangyang County was established; Emperor Gaozu of Han enfeoffed this place to Lu Bi, who was known as the King of Yan, and changed its name to the State of Yan; During Wang Mang's reign, it was renamed Guangyou, and the county was named Dai Rong.
