The four images of the Book of Changes are sun, lunar, shaoyang and shaoyin. The four images of geomantic omen are Zuo Qinglong, You Baihu, Qian Suzaku and Hou Xuanwu. According to the Confucian classics, the four directions, the north of Xuanwu Gongbei, the south of Suzaku, the east of Qinglong Pandong and the west of Baihu Juxi, should have qi in all directions, while the acupoints are in the middle, so it is auspicious to get soft qi and fierce to get it.
The left side is commonly known as dragon side, and the right side is commonly known as tiger side. Zuo Qinglong and you Baihu look out of the room, that is, from the direction of the gods. To enter the temple gate, you should enter from the right hand side, followed by Qinglong, and then come out from the left side, so the white tiger will not dare to approach. The green dragon and white tiger edge of indoor feng shui is also seen from the interior.
