Cultivation: Expel Outside Gods

Legend has it that in the ancient world, humans and "gods" lived together in the world, the heaven and earth were in chaos, and the world could not govern itself. Emperor Zhuanxu of the Later Xuan Dynasty separated the heaven and the earth through his act of extreme heavenly power. From then on, everything was reshuffled and put in its proper order. Since the mixing of humans and gods in the world has caused chaos in the world, why do people worship them in halls?
