The Forbidden City in Luoyang is called Wei Zicheng. Wei Zicheng, also known as Wei Zi Palace, is the main palace, political center and national symbol of Sui, Tang and Wu Zhou empires, located in the northwest corner of Luoyang, the capital of God. Founded in the first year of the great cause of the Sui Dynasty (605), [1] was used by the Tang Dynasty, the Five Dynasties and the Song Dynasty, and lasted for more than 530 years after seven dynasties [2]. It is the palace with the most dynasties in the history of China.

Weizi Town was the most magnificent palace group in the world at that time, and its architectural form was shocking, which affected the palace construction in East Asian countries. Especially the Tang Ming and Paradise built in the era of Wu Zetian made it unique and became a great miracle of the world. Weizi Town covers an area of about 4.2 square kilometers, which is six times that of the Forbidden City in Beijing in Ming and Qing Dynasties. [3]

1988, the site of Luoyang City in Sui and Tang Dynasties where Wei Zi was located was listed as the third batch of national key cultural relics protection units. In 2008, Luoyang City built the Luoyang City National Heritage Park in Sui and Tang Dynasties on the site of Weizicheng, and implemented the overall protection and exhibition project of Tang Ming, Paradise, Kyushu Pool and Yingtianmen sites in the park.

Weizicheng occupies an important position in the development history of ancient Miyagi in China, and it is a unique palace in the history of China. Its plane layout and architectural form laid the basic pattern of Miyagi in China, and it was a model of palace architecture after Sui and Tang Dynasties. It was imitated by the imperial palace in the Song Dynasty, Miyagi in the Yuan Dynasty and the Forbidden City in Beijing in the Ming and Qing Dynasties, and even influenced Japan, North Korea and South Korea and other East Asian countries.
