The Edict of Empress Ma of the Han Dynasty (Han Mingde Ma Huanghou Zhao) mentions those who are favored and noble being arrogant and unrestrained. The Book of Odes (Shijing), in the introductory commentary to the Airs of Kuai, mentions resentment of unrestrained behavior. The scholar Zheng Xuan notes that the term refers to deceitful, licentious, and excessive behavior that disregards the laws of propriety.
