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 if Xi 'an is called the national capital, people will generally call Luoyang the eastern 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 plain economy in the middle and lower reaches of the Yellow River is generally developed, and setting Luoyang as the east capital can consolidate economic rule.
