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).
Yueban
Between 155 and 166, the Xianbei or Syanbi (Ch. , Wade–Giles Hsien-pi, Hsien-pei), a former vassal tribe of the Xiongnu, united under Tian-Shih-huai conducted a series of campaigns against Northern Xiongnu, eventually defeating them and forcing them to flee west, which started a series of Xiongnu migrations (93 CE - circa 380 CE) westward to southern Siberia and Central Asia. (The Xiongnu have often been linked to the Huns that later invaded Europe from the Eurasian steppe, although the link has never been conclusively established. Likewise the Yueban of late antiquity have sometimes been known as the "Central Asian Huns".)
