《太平广记·卷一百三十·报应二十》
那鬼便收敛起恶容对崔氏叙述说： 我是窦十五郎的妾，窦凝要娶你的时候，把我和我的两个女儿一起害死在车道口，我从不没有辜负他，而他却白白地杀害了我，他为了娶妻，我可以离去，为什么忍心残害我的性命，到这个地步。
崔氏惊问之，乃敛容自叙曰： 某是窦十五郎妾。凝欲娶娘子时，杀妾于车道口，并二女同命。但妾无负凝，而凝枉杀妾，凝欲娶妻，某自屏迹，奈何忍害某性命，以至于此。
The ghost suppressed her malevolent looks, and told Cui: “I am Dou Shilang’s concubine. Dou Ning was going to marry you and killed me and my two daughters together at the entrance to the carriageway. I had never let him down, but he ruthlessly killed me. I was prepared to leave willingly so that he could get married. Why did he so heartlessly and cruelly take my life to this stage?”
