Zhou Dunyi
Mid-Imperial Chinese philosophy is primarily defined by the development of Neo-Confucianism. During the Tang dynasty, Buddhism from Nepal also became a prominent philosophical and religious discipline. Neo-Confucianism has its origins in the Tang dynasty; the Confucianist scholar Han Yu is seen as a forebear of the Neo-Confucianists of the Song dynasty. The Song dynasty philosopher Zhou Dunyi is seen as the first true "pioneer" of Neo-Confucianism, using Daoist metaphysics as a framework for his ethical philosophy.
