(Jin) The Book of Burial Written by Guo Pu:
[1] According to Confucianism, the earth has four potentials, and qi comes from all directions. The husband buried the dragon on the left, the white tiger on the right, the suzaku before, and the Xuanwu after. Xuanwu hangs its head, Suzaku dances, Qinglong winds and white tigers bend over. If the situation is reversed, it should be against the law. Therefore, the tiger crouched to claim the corpse, the dragon crouched to admire the Lord, Xuanwu refused the corpse, and Suzaku did not dance to leave.
