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).
Nanyue
The Western Valley (Xi'ou) lived in most of Guangxi and western Guangdong, with most of the population concentrated along the Xun River region and areas south of the Gui River, both part of the Xi River watershed. Descendants of Yi-Xu-Song, the chieftain killed resisting the Qin armies, acted as self-imposed governors of the Xi'ou clans. At the time of Nanyue's defeat by the Han dynasty, there were several hundred thousand Xi'ou people in Guilin Commandery alone.
