Did the ancients in China divide the sky like this?

China was also divided into starry sky in ancient times. This system is called "three walls, four elephants and twenty-eight dormitories".

The so-called "three walls" refers to the starry sky near the north celestial pole. In ancient China, it was divided into three areas, namely Ziwei Garden, Taiwei Garden and Tianshi Garden.

In ancient China, the area near the ecliptic was divided into 28 regions, that is, 28 nights. Among them, it is divided into four groups according to the east, west, north and south directions, each group has 7 nights, namely Oriental Dragon, Western White Tiger, South Suzaku and North Xuanwu, which are four elephants.

Twenty-eight lodgings, that is, seven lodgings of the Oriental Black Dragon (horn, sound, fork, room, heart, tail and dustpan); Seven nights in North Xuanwu (barrels, cows, women, emptiness, danger, houses and walls); Seven nights of western white tiger (kui, Lou, stomach, Chang, Bi, Gou, Shen); Seven Nights of South Suzaku (Well, Ghost, Willow, Star, Zhang, Wing, Qi)

The right wall of Edasich and Wei Zi, in which the left wall consists of eight stars, namely: Zuo Shu, Shang Zai, Shao Zai, Shang Bi, Shao Bi, Shao Wei and Shao Cheng. The right wall consists of seven stars, namely, right pivot, second lieutenant, upper auxiliary, less auxiliary, upper guard, less guard and upper cheng.

As we all know, the Big Dipper consists of seven stars, which are called Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang, respectively.

The names of the constellations of Sanyuan are basically named after official positions, palace institutions and objects. In addition, there are, for example, Chutian, Gai Hua, Chuanshe, Neijie, Tiancang, Tianchuang, Shisanhe and Sangong, which are basically a complete imperial institution.

Niusu * * * includes eleven constellations, namely Niusu, Miaodao, Zhinv, Yitai, Zuo Qi, Hegu, Youqi, Tianbi, Luo Yan, Tian Tian and Jiukan.

Dousu consists of Dousu, Tianya, Sword, Turtle, Dog, Celestial Pole, Tianhu, Tianyuan, Nongzhang and Dog Country.

Extended data

Three walls, four images and twenty-eight lodges are the divisions of the ancient starry sky in China, which originated long before the Zhou and Qin Dynasties. Sanyuan is the three areas around the north celestial pole, namely Ziweiyuan, Taiweiyuan and Tianshiyuan.

The four elephants are distributed near the ecliptic and the white road, circling the sky. Each image is divided into seven parts, called "Accommodation", with a total of 28 accommodations. Each star officer contains a number of stars ranging from one to dozens. The coverage of the sky area is also different. Among the numerous star officials, 365,438+0 occupies a very important position, that is, three walls and twenty-eight accommodations.

The ancient astrological zoning in China has a long history and its methods are self-contained. China's ancient astronomy has such a characteristic, because the geographical latitude of the observer is in the Yellow River basin, which is about 35 degrees north latitude, so there are only two parts of the celestial sphere area he attaches importance to and the celestial sphere area he attaches importance to observing, one part is the northern celestial sphere area where the north celestial pole is located, and the other part is the stars near the ecliptic and the equator of the celestial sphere.

The so-called north celestial pole is the direction of the true north of the earth. We can imagine connecting the north pole and the south pole of the earth with a straight line that can extend indefinitely. This straight line extends from the north and south poles of the earth to infinity.

The north part refers to the position of the north celestial pole, and the other side corresponds to the south celestial pole. However, our ancestors in the northern hemisphere can only see the north celestial pole.

In ancient China, in order to know the stars and observe the celestial phenomena, the stars in the sky were grouped together with the north celestial pole as the center, and each group had a name.

Such a star combination is called a star official. Each star officer contains a number of stars ranging from one to dozens. The coverage of the sky area is also different. Among the numerous star officials, 365,438+0 occupies a very important position, that is, three walls and twenty-eight accommodations.
