What are Zuo Qinglong, Right White Tiger, Former Suzaku and Post Xuanwu in the architectural ceremony?

The most accurate thing is to sit in a house facing south, which can be said to be Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu. Why should we sit where the north faces south? The reason is that the early origins of Qinglong, Baihu, Suzaku and Xuanwu were used for astronomical observation. Qinglong, representing the East, consists of seven lodging places: Kakuk, Kangsu, Su Chang, Su Fang, Shinjuku, Su Wei and Kyoku. Xuanwu represents the north, including Dousu, Niusu, Nvsu, Xu Su, dangerous houses and city walls. The White Tiger represents Su Kui, Lousu, Stomach, Pleiades, Soapy, Sudi and Betelgeuse in the west. Suzaku refers to Nanjing lodge, Ghost lodge, Liusu, Xingsu, Zhangsu, Wing lodge and Easy lodge. So green refers to oriental wood, white refers to western gold, black refers to northern water, and Zhu refers to southern fire. So standing in the south can be said to be left Qinglong, right White Tiger, former Suzaku and later Xuanwu. Later, Feng Shui master became the same communication language without joining Oriental Dragon and Southern Suzaku ... Later, it was agreed that front, back, left and right would replace south, north, east and west. Later, Feng Shui master said Qinglong Square ... Everyone knows that it means the left side of the house, and the white tiger means the right side of the house, so Suzaku is in front of the house, of course, and Xuanwu can easily understand its meaning. ........... is behind the house. In fact, strictly speaking, only houses facing south can use the expressions of Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu. The south of the three halls of the Forbidden City is called Wumen (C "Wu" Ding), and the north is called Xuanwu Gate.
