Friends who have seen the Chinese star map will find that in our star map, there is no star called 'Zi Wei'. Whether it is the former North Star 'Beijing Er' or the current North Star 'Gou Chen Yi', they all have their own names, but there is no star called 'Zi Wei', because Zi Wei itself is a phantom star.
Unlike other main stars, the core of the entire astrological chart, the Zi Wei star, is a phantom star, similar to our Tai Sui star. It is not a specific star, but it does have established operational rules. Zi Wei corresponds more to the Zi Wei Yuan, and if one must refer to a specific star, the Tai Chi Er in the Tai Chi star official of the Zi Wei Yuan might be more appropriate. This star had another name in ancient times, 'Di Xing', because at that time, Di Xing was the bright star of the northern celestial pole and had once served as the North Star.
The 'Shang Qing Ling Bao Da Fa' records: 'The Great Emperor of the North Pole, there is the Emperor's Seat in the Zi Wei Yuan. According to the 'Tian Wen Zhi', the southern pole enters the earth thirty-six degrees, and the northern pole exits the earth thirty-six degrees. The heavenly shape leans to the side, half above the ground and half circling the earth, all stars and energies rotate counterclockwise, the southern and northern poles are the pivot, only this remains stationary, thus the heavens can turn. The world sees it in the north, but it actually resides in the center of the heavens, being the lord of all stars and the sub-lord of the three realms, next to the Supreme Heaven, responding to the primordial energy, this is the North Pole Zi Wei Great Emperor, governing the Zi Wei Palace of the Central Heavens. It is said that the Zi Wei Great Emperor is the great deity of all heavens, the emperor of all gods and all killings in the three realms, deceiving the mortal world, defiling the upper mysteries, deserving of severe reform.' The 'Book of Jin - Astronomical Records' states: 'Zi Wei, the seat of the Great Emperor, is the constant residence of the Son of Heaven.'
In the traditional Chinese astronomical system, the celestial sphere is divided into three enclosures and twenty-eight lunar mansions. The three enclosures are Zi Wei Yuan, Tai Wei Yuan, and Tian Shi Yuan, while the twenty-eight lunar mansions are divided into the four symbols: Qing Long, Bai Hu, Zhu Que, and Xuan Wu. The three enclosures are located in the central area of the starry sky, with Zi Wei Yuan being at the very center. The stars surrounding the Zi Wei Yuan resemble subjects surrounding an emperor in the central area, thus Zi Wei Yuan is the place where the Heavenly Emperor resides, giving rise to the place where the earthly emperor resides being called the Forbidden City. Although Zi Wei Yuan is not visually directly above the starry sky, its relative position at the northern celestial pole does not change much in the entire celestial sphere. Whether day or night, it does not sink below the horizon, while other stars rise and set.
