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).
Luandi
The Luandi was a clan that held some of the highest positions in the Xiongnu society, including the title of chanyu within the Xiongnu confederacy. In the confederation, Luandi was a paternal dynastic tribe, Huyan was an initially maternal dynastic tribe, and Xubu was a subsequently maternal dynastic tribe. They were the three most prominent tribes ("Houses" in N. Bichurin) in the Xiongnu.
