《资治通鉴·唐纪·唐纪七十五》
刘夫人带领李存孝出邢州城去拜见李克用。李存孝跪在地上向李克用磕头认罪说： 儿子我刚立了一点功劳，李存信便威逼我，以致于失去考虑到这种地步！ 
夫人引存孝出见克用，存孝泥首谢罪曰： 儿粗立微劳，存信逼儿，失图至此！ 
Madam Liu led Li Cunxiao out of Xingzhou City to pay respects to Li Keyong. Li Cunxiao knelt on the ground and banged his head on the ground to admit his guilt, saying: My son just made a small contribution, and Li Cunxin threatened me, and drove me to the point of losing all sense!
