Architecture of Mongolia
The Xiongnu confederation ruled present-day Mongolia from the third century BCE through the first century CE, living in portable, round tents on carts and round yurts. The Xiongnu aristocracy lived in small palaces, and their villages were protected by huge walls. S. I. Rudenko also mentions capital construction built of logs. Archaeological excavations indicate that the Xiongnu had towns; their chief city was Luut Hot (Dragon City).
Wusun
The Wusun subsequently took over the Ili Valley, expanding over a large area and trying to keep away from the Xiongnu. According to Shiji, Wusun was a state located west of the Xiongnu. When the Xiongnu ruler died, Liejiaomi refused to serve the Xiongnu. The Xiongnu then sent a force to against the Wusun but were defeated, after which the Xiongnu even more than before considered Liejiaomi a supernatural being, avoiding conflict with him.
