Why is Luoyang called Du Dong?

Because many dynasties in our country established their capitals in Xi 'an, relatively speaking, Luoyang is in the east of Xi 'an. In addition, many dynasties built their capitals in Luoyang, so for the convenience of distinction, people generally call Luoyang the East Capital.

Luoyang was called the East Capital only from the Sui Dynasty. In terms of area, Luoyang in the past was much bigger than Luoyang now. Later, Luoyang and Chang 'an were also called the second Beijing of the East and the West, and they were called the second Beijing of the East and the West for a long time, about two thousand years.

The economy in the middle and lower reaches of the Yellow River is generally developed. The capital of Luoyang can not only consolidate the economic rule, but also strengthen the political rule of the whole country. Therefore, in view of this, Yang Di designated Luoyang as the eastern capital, and the opening of the Beijing-Hangzhou Grand Canal also made Luoyang the center of the country.

The capital-building concept of Luoyang city in Sui and Tang Dynasties

Luoyang City in Sui and Tang Dynasties was designed and built by Yuwen Kai. Yu Wenkai perfectly combined the planning and design of Luoyang city in Sui and Tang Dynasties with Luoyang landscape, and truly realized the planning concept of harmony between man and nature.

During the Sui and Tang Dynasties, the southernmost axis of Luoyang City's Imperial City was facing the Longmen Gate, which made the south gate of Miyagi City (Wei Zicheng) and Imperial City (Taiwei City) face the Longmen Gate and Gate. Miyagi is located in the highest place in the northwest of the capital, symbolizing the Polaris in the center of the sky. Therefore, Miyagi in Luoyang City in Sui and Tang Dynasties is also called "Wei Zi Palace".
