《旧五代史·后周·列传十》
但性情轻浮急躁，行为轻率，把天下的事当作自己的事，每有报告请示，总是任性而为，太祖听取而顺着他，就高兴地退下，稍不允许认可，就立即生气，不尊重的话就马上随口而出。
然为性轻躁，举措率易，以天下之事为己任，每有启请，多自任情。太祖从而顺之，则忻然而退；稍未允可，则应声而愠，不逊之语随事辄发。
However, his disposition was frivolous and hasty, his conduct was reckless, he treated the affairs of the world as his own, every time he reported and requested instructions, he always acted willfully, if Taizu listened to and humored him, he would retire happily, if Taizu somewhat did not allow or approve it, he would be angry immediately, and disrespectful words would immediately come out of his mouth.
