The ancient city site of Aolunsumu, also known as Zhaowang city, was once the capital of the Wanggu Tribe. The tribe has a close relationship through marriage with Genghis Khan, the founder of the Yuan Dynasty ( 1271-1368).

The ancient city wall was once 570 meters wide and 960 m in length, with four gates facing different directions. A barbican entrance - a semicircular enclosure between the outer and inner city gates – also stood outside the city wall to protect the city.

Cultural relics discovered at the site of the ancient city include a mansion, a Nestorian church, a Catholic church, a lamasery and a Confucian temple.
