《太平广记·卷四百七十·水族七》
十个月后，女子生下三只小水獭，本想杀死它们，可是有的人说： 那个妖魅尚且守信用，我们是人难道还不讲信用吗！不如放了它们。 
后旬月，产獭子三头，欲杀之。或曰： 彼魅也而信，我人也而妄，不如释之。 
Ten months later, the woman gave birth to three little otters. She wanted to kill them, but some said: "The demon is keeping his word, yet we humans are not as honest! We should let them go."
