《旧五代史·后周·列传六》
所写的文章诗赋，因忙于国事而散失的以外，尚能收集到的，编成一本私家集子，从中可见我的志趣，理解我的人，怪罪我的人，不知各有多少。
所著文章篇咏，因多事散失外，收拾得者，编于家集，其间见其志，知之者，罪之者，未知众寡矣。
There are still some of my essays, poems, and rhapsodies that remain after the ones that were lost due to my attention to affairs of state. I compiled them into a private collection, which reveals my aspirations. I do not know how many people will find fault with me and understand me.
