《旧五代史·后晋·高祖纪一》
当时，秦王从荣上奏： 我见北方频频报告，契丹族移帐边塞，吐浑、突厥已侵犯我边陲，戍守的士兵虽多，但没有统帅，应尽早任命一员大将，以安定云州、朔州。 
是时，秦王从荣奏： 伏见北面频奏报，契丹族移帐近塞，吐浑、突厥已侵边地，戍兵虽多，未有统帅，早宜命大将一人，以安云、朔。 
At that time, the King Qin, Cong Rong, memorialized: "I have seen frequent reports from the north. The Khitans moved their camps to the border, and Tubo and the Turks have invaded our border. Although there are many soldiers guarding the border, there is no commander. We should appoint a general as soon as possible to stabilize Yunzhou and Shuozhou."
