Three Gorges, namely Ziwei Gorge, Tianshi Gorge and Taiwei Gorge, are one of the star officials who divided the starry sky in ancient China, and together with the 28 lodges on the zodiac, they are called "Three Gorges and 28 lodges".
The ancients imagined the seven lodgings in the east, north, west and south as four kinds of animal images, which were called "four elephants". In the twenty-eight lodges, four images are used to divide the stars in the sky, also known as "four gods" and "four spirits". The appearance of the Four Elephants is relatively early, and the embryonic form has been found in Shangshu Yaodian.
the images of four animals composed of the above seven lodges are collectively called "four images", "four dimensions" and "four beasts". The ancient people used the appearance and arrival time of each of the four elephants and the twenty-eight stars to judge the seasons.
The ancients looked at the solar terms in the direction of the south, so there was the saying that there was a dragon in the left east, a white tiger in the right west, Xuanwu in the north and Suzaku in the south.
Twenty-eight Hostels is one of the themes in Chinese traditional culture, which is widely used in ancient astronomy, religion, literature, astrology, astrology, geomantic omen, lucky selection, etc. Different fields have given it different connotations, and the related contents are very complicated.
The seven stars, Jiao, Kang, Shi, Fang, Xin, Wei and Ji, make up the image of a dragon. The vernal equinox is in the eastern sky, so it is called "Seven Hostages of Oriental Qinglong".
The seven stars, Dou, Niu, Female, Xu, Danger, Room and Wall, form a group of intertwined images of turtles and snakes. The vernal equinox season is in the northern sky, so it is called "Seven Nights in Northern Xuanwu".
The seven stars, Kui, Lou, Wei, Ang, Bi, Zui and Shen, form the image of a tiger. They are in the western sky at the vernal equinox, so they are called "the seven nights of the western white tiger".
Well, Ghost, Willow, Star, Zhang, Wing and Taw, these seven stars form the image of a bird, and the spring equinox season is in the southern sky, so it is called "seven nights of southern Suzaku".
The formation and meaning of the names of the four images and twenty-eight lodges in the Three Walls of China in astronomical history reflect the rich connotation of Chinese traditional culture and will give people a lot of inspiration. The ancients in our country believed that heaven and man could interact with each other, and that some celestial phenomena in the sky always indicated that something was going to happen in a certain time and place on earth, so the naming of stars corresponded to everything on earth.
