Historical origin

In ancient times, the ancients who pursued order not only planned the sky in an orderly way, but also corresponded the stars with the ground areas one by one. This correspondence is called "dividing stars" in astronomy and "dividing fields" underground. The theory of dividing line originated in ancient times. The reason why the celestial body area corresponds to the geographical area is to cooperate with the astrological theory for astronomical observation.

According to the twelve stars, such as longevity, fire, wood analysis, astrology, mystery, bow, girder, stone god, quail head, quail fire and quail tail, the ancients divided the positions of States and countries on the ground. As far as astronomy is concerned, it is called fractional star; On the ground, it is called the dividing line. The reason why the celestial star region corresponds to the geographical region is because its original purpose is to cooperate with astrology theory for astronomical observation.

Han Dynasty is the first great development period after the reunification of China, and it is also an important period of economic and cultural exchanges between the North and the South. By the Han Dynasty, this division had been described in detail in Geography of Hanshu. After the Han Dynasty, the division of astronomy changed from a practical "astrology" to a strict system carrying people's world outlook.

Twenty-eight books, Huainan Xun and Shi Ji Tian suan, respectively correspond to the geography of the thirteen States of the Eastern Zhou Dynasty and the twelve States of the Emperor Wu of the Han Dynasty. Later dynasties changed between the 13th Division and the 28th Division.

In the ancient context of China, "number of stars" and "numerous stars" refer to "constellations", that is, the combination of stars (possibly one or more). There were "twelve stars" in the pre-Qin period in China, namely astrology, occultation, Li Wei, Loulou, Liang, Shi Shen, quail head, quail fire, quail tail, longevity star, fire and wood analysis, which are similar to the western zodiac.
