The Nangong was built during the reign of Emperor Guangwu of Han Dynasty (25 ~ 57), the Bei Gong was built during the reign of Emperor Hanming (58 ~ 75), and the Eastern Palace and the Western Palace were successively built during the reign of Emperor Hanhe and Emperor Lingdi (89 ~ 189), which shows that the palace construction in Luoyang lasted for a long time.

The main entrance of the Nangong in Luoyang in the Eastern Han Dynasty, that is, the main entrance to the south of Beijing, is located to the east of Luoyang City. Bei Gong is located in the northeast of Luoyang, and the two palaces in the north and south are all on the north and south walls of the capital, seven miles apart. These palaces are much smaller than those in Chang 'an in the Western Han Dynasty, but they are also very elegant. According to "Three Auxiliary Huang Tu", the palace building takes "Mulan as the curtain and Wenxing as the pillar; Jin Pu Yu Hu, Hua Yun Bi Yan, carved jade, re-porch Lou threshold, clear Zodan, left city right flat; Gold is the wall belt, and it is surrounded by jade and jade, and the wind makes it sound exquisite. " It can be seen that the Eastern Han Palace is also very exquisite and rich.

The ancient city of Luoyang experienced frequent ups and downs. At the end of the Eastern Han Dynasty, the city declined with the war. Later, in the Northern Wei Dynasty, the capital was built here, and the palace city flourished again.
