孝経
In Confucian, Chinese Buddhist and Taoist ethics, filial piety (, "xiào"), is a virtue of respect for one's parents, elders, and ancestors. The Confucian "Classic of Filial Piety", thought to be written around the late Warring States-Qin-Han period, has historically been the authoritative source on the Confucian tenet of filial piety. The book, a purported dialogue between Confucius and his student Zengzi, is about how to set up a good society using the principle of filial piety. Filial piety is central to Confucian role ethics.
