The ancients said: "black dragon, White Tiger, Suzaku, Xuanwu, the Four Spirits of Heaven, Fang Ye." Therefore, the "Four Spirits" have become the "Gods of the Four Sides", that is, the "Four Elephants" in space: the Oriental Dragon, the Western White Tiger, the Southern Suzaku and the Northern Xuanwu.
"Qinglong, Suzaku, Baihu and Xuanwu" in geomantic omen mainly refers to geographical orientation and attributes of five elements.
Ancient houses generally sit facing south, with Suzaku in the south in front, Xuanwu in the north behind, Qinglong in the east on the left and White Tiger in the west on the right. Therefore, it is said that "left green dragon and right white tiger, before Suzaku and after Xuanwu".
