Wei Zi is suitable for this palace.

The origin of the Forbidden City comes from the purple stars in the sky. It is said that the ancient Emperor of Heaven lived on the Purple Star, so the Emperor of Heaven named his place after the Forbidden City.

The Forbidden City experienced two emperors and was the place where the emperors of Ming and Qing dynasties lived. The Forbidden City was built by Judy, the founder of the Ming Dynasty, and has 70 palaces.

The walls of the Forbidden City are red, which symbolizes wealth in ancient times. In ancient times, when getting married, only the wife's wedding dress could be red, and other concubines' wedding dresses could only be close to red, and they could not wear red wedding dresses.

The tiles in the Forbidden City are yellow, symbolizing the ancient royal family. Only the emperor can wear bright yellow clothes. If someone wears yellow clothes without permission, they may be considered suspected of rebellion.

If the Forbidden City is named after a color, it may be called the Red Forbidden City or the Yellow Forbidden City, but the ancient emperor had to be different and named it the Forbidden City.

Because emperors have the dream of immortality, they are very concerned about geomantic omen and astronomy. Knowing that Zixing was the residence of the Emperor of Heaven, they changed their residence into the Forbidden Palace.

In ancient times, almost every emperor did not want to die in his later years, but wanted to live forever. They began to pay attention to astronomy in order to find a way to live forever, because it was generally believed that there were immortals in the sky.

As a result, the emperor, unable to satisfy his long-lived wish, began to fantasize that he was the most distinguished person in the world. The highest fairy in the sky lives in Zixing, so the most noble people in the world live in harmony with the sky, hence the name of the Forbidden City.

The reason why it is called the Forbidden City instead of the Purple City is that the Forbidden City represents authority, and a forbidden word separates the emperor from the civilians, making the emperor look high.
