《礼记·檀弓下》
子亢说： 用活人殉葬，是违礼行为。尽管如此，如果一定要有人在地下侍候他养病，谁也没有他的妻子和管家合适。
子亢曰： 以殉葬，非礼也；虽然，则彼疾当养者，孰若妻与宰？得已，则吾欲已；不得已，则吾欲以二子者之为之也。 
Zikang said: Using living people as burial objects is against etiquette. Even so, if someone must be buried with him to take care of his illness, no one is more suitable than his wife and butler.
