Noun explanation: Ziweiheng

Are you sure you are a noun explanation?

This seems to be an astrological area.

The north pole of Ziweiyuan is the center, based on the cluster near the North Pole, including the sky area within 50 degrees north latitude. In this range, the most obvious signs are the left and right walls. When night falls and the weather is clear, we will see the twinkling stars all over the sky. At this time, facing north, we can see the Ziwei Garden in the center of the sky.

The wall consists of eight stars on the left and seven stars on the right, which are connected by an imaginary line, symbolizing the palace wall. There are two doors on the wall. The front opening is the south gate, facing the bucket handle of the Big Dipper. On the back of the wall is the North Gate, facing the direction of Su Kui. Every star that makes up the Great Wall is named after the official name used by the Zhou Dynasty. Looking closely at these official names, they are led by the prime minister, some attendants and guards who are responsible for safeguarding the security of the palace, and the prime minister and assistant minister who are responsible for the indoor and outdoor affairs of the king. A second lieutenant was added. Because he is a judicial official sent by the state to take charge of the palace prison. There are two main constellations on the wall of Ziwei Garden, one of which is Shu Tian, and there are four bucket-shaped stars around it in the west. There is a string of little stars in the south, the first is the harem, the legendary queen mother, and further south is the illegitimate child, the emperor star and the prince. The other column is the six stars of Hook Chen, and the four little stars surrounded by Crookedstar are called Emperor. This is an extremely important star name, which should be used as the North Star in history. Among them, Hooke Chen Yi is the Polaris used in modern times, and it is also the most prominent and brightest star in these two series of stars. In addition, there are "four-star maids" and "five-emperor inner seats" serving the Emperor of Heaven, which represent the different positions of the Emperor of Heaven, and so on. Outside the wall of Ziwei Garden, there are some palace facilities, such as two kitchens, a heavenly kitchen and an inner kitchen, a bed for sleeping, a prison for holding prisoners, Wenchang Palace where civil servants are located, and the emperor's car when traveling.
