Xuanxue was a philosophical school that combined elements of Confucianism and Taoism to reinterpret the I Ching"," Tao Te Ching"," and "Zhuangzi." The most important philosophers of this movement were Wang Bi, Xiang Xiu and Guo Xiang. The main question of this school was whether Being came before Not-Being (in Chinese, "ming" and "wuming"). A peculiar feature of these Taoist thinkers, like the Seven Sages of the Bamboo Grove, was the concept of "feng liu" (lit. wind and flow), a sort of romantic spirit which encouraged following the natural and instinctive impulse.
