《新五代史·世家·前蜀世家第三》
王衍的母亲徐氏临刑时呼叫说： 我儿子拿一个国家投降，反而被杀死，信义都不要了，我知道灾祸不久就要来了！ 
衍母徐氏临刑呼曰： 吾兒以一国迎降，反以为戮，信义俱弃，吾知其祸不旋踵矣！ 
When Wang Yan's mother Xu Shi was about to be executed, she shouted: My son traded a country to survive, but was killed in the end. That was a betrayal of faith. I knew that disaster was approaching!
