What does the Moon Rise in Dongshan and Wander in the Bullfighting Room mention about the universe?

There is something wrong with the explanation upstairs. It's not Beidou and Petunia who fight bullfights, but Dou Su and Niu Su of the 28th Hotel.

This constellation corresponds to Sagittarius in the west, and Taurus corresponds to Capricorn.

According to the time when Su Dongpo wrote Cliff Fu, it is more realistic to say that the moon hovers between Sagittarius and Capricorn on July 16, and will not go to Aquila and Ursa major.

By the way, on the 28th night, because the planets in the solar system revolve around the sun with * * *, the sun and the five stars in Jin Mu will revolve around the ecliptic. Although the orbit of the moon has an included angle with the ecliptic, it is not far from the ecliptic. Therefore, in ancient times, both China and the West attached great importance to this area. In the west, the ecliptic was divided into twelve constellations, while in ancient China, the celestial sphere near the ecliptic was divided into 28 regions, each representing a night, namely:

The seven nights of the Oriental Black Dragon are the horn, kang, edge, room, heart, tail and dustpan.

The seven nights in Xuanwu in the north are fighting, cows, women, air, danger, houses and walls.

The seven residences of Xibaihu are Kui, Lou, Wei, Chang, Bi, Gou and Shen.

The seven nights of South Suzaku are well, ghost, willow, star, Zhang, wing and bird.

Moreover, China also corresponded these divisions with geographical locations, and thought that there were some changes in which area in the sky, which indicated that there was something on the ground. This correspondence is called "dividing line"

For example, in Wang Bo's Preface to Wang Teng-ting, there is a saying that "things are valuable, and the dragon light shoots the bulls to fight the market", which is also an allusion related to this bull fight. It is said that during the Jin Dynasty, there was a purple generate between cowhouses. According to this division, Fengcheng county, south of Nanchang, has a treasure suppressed, which is very depressing, so it is emitting gas fields. So the court took a person who knew how to calculate the dividing line and went to the local county for treasure hunting. Later, two swords were dug up in the underground of the prison, namely the legendary second lieutenant and shovel (also known as Longquan and Taiya). When I went to see the stars again, the purple gas disappeared.
