What are the four gods and twenty-eight stars? What do you care?

Analysis:

The four gods, namely, Qinglong, Suzaku, Baihu and Xuanwu, are the sacred animals guarding the southeast and northwest in ancient Chinese legends. Their order is southeast and northwest: Qinglong, Suzaku, Baihu and Xuanwu.

There are records of 28 stars in early summer. Every star is made up of several stars, and some names appear in The Book of Songs and Historical Records. According to the position of 28 stars, it is divided into seven nights of Qinglong, seven nights of Suzaku, seven nights of Baihu and seven nights of Xuanwu. The specific names are as follows:

Seven nights in Qinglong: Jiao Mujiao Kang Jinlong Nyctereute Fang Ri Rabbit Heart Moon Fox Tail Fire Tiger Basket Water Leopard

Suzaku Seven Nights: Muan Jing Ghost Golden Sheep, Six Rabbits, Zhang Yuelu, Winged Fire Snake and Water Worm.

White tigers in the seven nights: the golden dog, the stomach soil, the pheasant and the Bigou fire monkey.

Seven nights in Xuanwu: unicorn, ox, Taurus, female soil, bat, virtual sun mouse, dangerous moon, swallowing room fire, pig wall water.

Twenty-eight stars are valued by twenty-eight gods in turn, that is, one night represents one day and twenty-eight nights represents twenty-eight days, just as seven obsidian represents seven days a week, with Japanese obsidian as Sunday, moon obsidian as Monday, fire obsidian as Tuesday, water obsidian as Wednesday, Muyao as Thursday, Jin Yao as Friday, Earth obsidian as Saturday and seven stars. In ancient China, there was no week, and the twenty-eight obsidian represented every day around.

Twenty-eight stars are an important creation of ancient astronomy in China. They divided the stars passing through the south meridian into 28 groups, and each group was named by one word: horn, sound, surname, room, heart, tail, dustpan, bucket, cow, female, deficiency, danger, room, wall, kui, building, stomach, ang, bi, tapir, ginseng, and so on.

Twenty-eight stars are divided along the ecliptic and equator; Since ancient times, people have set 24 solar terms according to the appearance of the four seasons and the transit. The ancients divided the twenty-eight parts into four star regions, named them: Oriental Dragon, Northern Xuanwu, Western White Tiger and Southern Suzaku, and each star region had seven nights.

Twenty-eight constellations revolve around the surface of celestial atmosphere, and control the celestial phenomena in the east, west, north and south directions respectively, with the change of day and night, and with the change of yin and yang. However, in ancient geomantic omen, the division was to divide the 28 constellations into four directions, namely, four image lines: Zuo Qinglong, You Baihu, Qianzu zaku and Houxuanwu.

The four images in the Book of Changes are Lao Yang, Laoyin, Shaoyang and Shaoyin, and the four images in Feng Shui are "Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu". Confucian classics say that "Fu Xuanwu Gongbei, Suzaku South, Qinglong Pandong, and White Tiger Gathering West, the four potentials should be in all directions, and the acupoints are in the middle. If you get soft gas, you will be lucky, and if you get it, you will be fierce." The location of these four images is the geographical location of Feng Shui. Front, back, left and right are all balanced, harmonious, supple and prosperous, and only in this way can we have a good geography.

For the so-called left green dragon, right white tiger, former Suzaku, and later Xuan fighters, this is sitting north to south; If you sit south to north, on the contrary, it is left white tiger and right dragon, before Xuanwu and after Suzaku; Because dragon belongs to oriental wood, white tiger belongs to western gold, Xuanwu water in the north and Suzaku fire in the south, this is certain. It's just a habit that artists always open their mouths at the left Qinglong and the right White Tiger, regardless of the east, west and north.

In ancient times, in order to observe the movements of the sun, the moon and the five planets (gold, wood, water, fire and earth), people chose 28 constellations near the ecliptic and equator as symbols, which are collectively called 28 constellations, or 28 stars. Their names are: Jiao, Kang, Shi, Fang, Xin, Wei and Ji (these seven stars constitute the image of the dragon and the vernal equinox. Dou, Niu, female, empty, dangerous, house, and wall (these seven stars form a group of tortoise and snake intertwined images, which appear in the northern sky at the vernal equinox), so they are called "seven nights in the northern Xuanwu", and the seven stars of Kui, Lou, Stomach, Ang, Bi, Mouth and Shen (which form the image of a tiger and appear in the western sky at the vernal equinox) are called. An animal image composed of the above seven nights is collectively called Four Elephants and Four-dimensional Four Beasts. The ancients used the appearance and arrival times of the four elephants and the twenty-eight constellations to determine the key methods of seasons. The five elements of the twenty-eight constellations, the tools used by modern Feng Shui masters, were determined from here. From the above data, it can be proved that the 28 constellations are the changes of the five elements in a year, rather than the usage of the 28 solar terms used in the modern peasant calendar. The ancients resigned themselves to their fate and looked at the solar terms in the south, so there were left oriental dragons, right western white tigers and post-oriental tigers.
