《旧五代史·后周·世宗纪二》
 朕蒙先帝的英灵，居皇帝的高位，从事政治还短，经历世事不深，经常担心昏庸愚昧，不能承担重任。
朕承先帝之灵，居至尊之位，涉道犹浅，经事未深，常惧昏蒙，不克负荷。
I received the spirit of the first emperor and held the high position of the emperor. I have been engaged in politics for a short time and have little experience in the world. I often worry that I am dull and ignorant and cannot bear the heavy responsibility.
