《旧五代史·后唐·列传三》
长兴年中，李从荣以秦王身份兼任天下兵马大元帅。李从荣便请以严卫、捧圣步骑两指挥为秦王府衙兵，每次上朝，以数百骑兵随行，出行就张弓挟箭，满街奔驰。接受元帅一职后，便令其府属僚佐以及四方游士，各写《檄淮南书》一篇，陈述自己将扫清天下之意。起初，有言事的人请为亲王设立一名师傅，明宗向近臣询问，管事的人因李从荣名声势力日益隆盛，不敢违抗旨意，便上奏说 ：王官适宜委任。 
从荣为诗，与从事高辇等更相唱和，自谓章句独步于一时，有诗千余首，号曰《紫府集》。长兴中，以本官充天下兵马大元帅。从荣乃请以严卫、捧圣步骑两指挥为秦府衙兵，每入朝，以数百骑从行，出则张弓挟矢，驰骋盈巷。既受元帅之命，即令其府属僚佐及四方游士，各试《檄淮南书》一道，陈己将廓清宇内之意。初，言事者请为亲王置师傅，明宗顾问近臣，执政以从荣名势既隆，不敢忤旨，即奏云： 王官宜委。 
In the middle of the Changxing era, Li Congrong, in his capacity as King of Qin, concurrently served as Commander-in-Chief of the天下bingma (battalions). Li Congrong then requested that the two commands of the Yansheng and Pingsheng cavalry serve as his Qin Palace Guards. Every time he went to court, hundreds of horsemen would accompany him, and when he went out, he would carry a bow and arrows and gallop through the streets. After he took up the post of Commander-in-Chief, he ordered his subordinates and itinerant scholars from all directions to each write an article called "Gexihuainan shu" (Denouncing Huainan), in which they expressed their intention to sweep away the world. At first, someone memorialized the court, requesting that a mentor be appointed for the Prince. Emperor Mingzong asked his close advisors about it. The relevant official, because Li Congrong's reputation and influence had grown stronger with each passing day, did not dare to disobey the order and so he memorialized the court, saying "Perhaps it would be suitable to appoint Wang Guan."
