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).
Xiongnu
The "Records of the Grand Historian" (vol. ) state that when the Xiongnu noted down something or transmitted a message, they made cuts on a piece of wood; they also mention a "Hu script".
Xiongnu were a nomadic people. From their lifestyle of herding flocks and their horse-trade with China, we can conclude that their diet consist mainly of mutton, horse meat and wild geese that were shot down.
