《新五代史·列传·杂传第三十》
赵岩说： 古代称王的人必定在郊外祭祀天地，陛下登位以来还没有在郊外祭天，议事的人认为朝廷和藩镇一样，像这样怎么能威重天下？
岩曰： 古之王者必郊祀天地，陛下即位犹未郊天，议者以为朝廷无异籓镇，如此何以威重天下？
Zhao Yan said, "In ancient times, all emperors performed sacrifices to heaven and the earth at the郊外. Since Your Majesty ascended to the throne, you have never performed sacrifices at the郊外. It is said that the court and the vassals are equal. How can you impress the world in this situation?
