《汉书·传·贾邹枚路传》
所以，圣王一旦醒悟，就会舍弃宠信子之之心，也不会认为田常是贤人而喜欢他，而要策封比干的后人，为纣王杀死的孕妇修墓，因而为天下建功立业。为什么呢？
是以圣王觉寤，捐子之之心，而不说田常之贤，封比干之后，修孕妇之墓，故功业覆于天下。
So the holy king, once he has become aware of his duties, will not allow partiality towards his pet ministers, and will not like Tian Chang because he is wise, but will endow the descendants of Bi Gan, and build tombs for the pregnant women killed by King Zhou, thus establishing an everlasting achievement in the world. Why is that?
