(1) The ancient astrologers in China used the changes of astronomical phenomena to predict the good and bad fortune of the world, and they corresponded the starry sky region with the countries and states on the ground, which was called the dividing line. According to China's ancient astrology, every county and state on the earth corresponds to a certain area in the sky, and the astronomical phenomena in this area indicate the good or bad luck of each corresponding place. The division originated in the Spring and Autumn Period and the Warring States Period. It was first seen in Zuozhuan, Guoyu and other books, and the division reflected by it is generally bounded by twelve stars. The earliest story contained in it is that the astronomical phenomenon on the day when King Wu was attacked was that the old star was in quail fire, so the division of the week was quail fire. After the Warring States period, there was also a 28-night dividing line such as Huainanzi Astronomical Training. Later, due to the interconnection of twelve stars and twenty-eight lodges, the two divisions gradually coordinated and communicated after the Western Han Dynasty. Specifically, it is to regard a star as the dividing line of a country, a star as the dividing line of a state, or conversely, regard a country as the dividing line of a star and a state as the dividing line of a star. For example, Wang Bo's Preface to Wang Tengting: "Zhang Yu is the old county, and Hongdu is the new house. The stars spread their wings and meet Lu Heng. " In other words, Nanchang, Jiangxi is located on the dividing line between Yisu and Suye. Li Bai's Shu Dao Nan: Panting, we brushed Orion and crossed the well star. Then, we held our chest with our hands and groaned, and collapsed to the ground. Betelgeuse is the dividing line between Yizhou (now Sichuan) and Yongzhou (now most of Shaanxi and Gansu), and the Shu Road spans Yizhou and Yongzheng. Visiting a well means that Shu Dao is on the extremely high mountains of Yi and Yong countries, and people have to raise their heads and touch the stars in the sky to reach it.

It should be pointed out that this division is purely superstitious. The so-called relationship between heaven and earth is completely determined by human beings, so it is inevitable that there are differences between families in past dynasties.

Twelve stars and twenty-eight lodgings, the country and state are divided as follows (in the Book of Jin, Tian Wen Zhi).
