In the fourth year of Zhiyuan (AD 1267), a new city was built in the northeast of Jinzhong Zhongducheng (now Beijing). In the ninth year of Zhiyuan (AD 1272), it was renamed Dadu and became the capital of Yuan Dynasty.

Dadu in Yuan Dynasty, referred to as Dadu for short, is called cambaluc in Turkic, which means Khan's residence. Its city site is located in the downtown area of today's Beijing, with the ruins of Metropolitan Tucheng in the Yuan Dynasty in the north, Chang 'an Avenue in the south and the East-West Second Ring Road.

Extended data:

As the political center of the whole country, the capital of the Yuan Dynasty was built around the magnificent palace. The spectacular imperial city is located in the south-central part of the capital, with a wall width of 20 miles.

To the east of the imperial city is Miyagi, covering an area of about nine miles. Living in palaces and castles as far as the eye can see, relatives of the royal family and the country are surrounded by thousands of palace guards, eunuchs and maids, and live a life of drunkenness.

However, due to the incompetence of the last emperor, Yuan Shundi, this good day is coming to an end. After the peasant uprising broke out at the end of the Yuan Dynasty, the world was in chaos, people were distracted, and most areas were often isolated from the south, which led to the inability to transport food from the south to the north in time.

Later, there was a serious famine in the city, and the people bore the brunt. Many poor people struggle to death, and the dead fill the ditch.
