The term refers to two fundamental states in the existence of things, namely, movement and stillness. These two kinds of states are antithetic, but they also rely on each other and change into each other. Ancient Chinese had different views about the constant or the intrinsic state of the existence of things. Confucian scholars believed that “movement” was the fundamental state of existence of things, and that all things under heaven and on earth were in perpetual change and motion. Daoist scholars held that concrete things in motion were originally still, and that they would eventually return to stillness. Buddhists maintained that things were inherently all still and that the movements and changes people saw were just illusionary.
