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).
Former Zhao
By the 280s, a huge number (approximately 400,000) of Xiongnu herdsmen resided in the Ordos Desert and Bing, a political division including modern-day areas of the whole Shanxi province, southwestern part of Inner Mongolia and eastern part of Shaanxi province, after Cao Cao moved them there and split them into "five departments" (五部, pinyin Wǔbù). The Southern Xiongnu continued their nomadic lifestyles of the steppes with horse breeding and to some extent agriculture. In spite of significant loss of Chinese sedentary population, the Chinese portion of the population in the state is estimated to be around 1,500,000. In addition to the Southern Xiongnu nomads, the state numbered 1,000,000 of other nomadic tribes, mainly Jie, Xianbei, Di, and Qiang, for a total of approximately 1,400,000 nomadic population, or 200 thousand yurts.
