Extended data:
Qinglong, Baihu, Suzaku and Xuanwu originated from the belief in the stars in ancient China. In ancient China, the sky was divided into four regions: east, north, west and south, which were called "four elephants", namely, the black dragon in the east, the Xuanwu (tortoise and snake) in the north, the white tiger in the west and the suzaku in the south. This "four elephants" is the image of four animals imagined by the ancients by connecting seven nights in each direction.
Suzaku: It is south in azimuth. Xuanwu: bearing north. Qinglong: It represents the East in azimuth. White tiger: it represents the west in orientation.
