The origin of Idioms
Wang Yucheng of the Song Dynasty wrote in the book of burying Yang Fei instead of Li Kui's admonition: "Di Mei steals the name of his wife, and Kun Zhong's corpse is sealed by the earth. There is no difference between the curtain and the mat, so the emperor's heart swings above and the heart resents below."
