Ordos Plateau
In Chinese accounts, the Xiongnu first appear at Ordos in the "Yizhoushu" and "Shanhaijing" during the Warring States period before it was occupied by Qin and Zhao. It is generally thought to be their homeland, however when exactly they came to occupy the region is unclear, and it might have been much earlier than traditionally thought, as suggested by archaeological finds. As the Xiongnu expanded southward into Yuezhi territory around 160 BC under their leader Modun, the Yuezhi in turn defeated the Sakas (Scythians) and pushed them away at the Issyk Kul. It is thought the Xiongnu also occupied the Ordos area during the same period, when they came in direct contact with the Chinese. From there, the Xiongnu conducted numerous devastating raids into Chinese territory (167, 158, 142, 129 BC). The Han Dynasty started to fight the Xiongnu in the 2nd century BC under emperor Han Wudi, and colonized the area of the Ordos under Shuofang commandery in 127 BC. Prior to the campaign, there were already commanderies established earlier by Qin and Zhao until they were overrun by the Xiongnu in 209 BC.
Xichang
The Qiongdu were the local people at the time of contact with China. The county of Qiongdu is attested in the area from the Han dynasty. Under the Song, a local lord was given the title of "King of the Qiongdu" ("Qiongdu Wang"). The area formed part of the medieval Kingdom of Dali and was subdued by the Mongolians from 1272–4, after which it was incorporated into Yunnan of the Yuan dynasty. It was organized as the Jiandu Ningyuan duhufu, qianhufu, or wanhufu but continued to be often known as Jiandu. In the book of his travels, Marco Polo recorded that the people of Jiandu and its hinterland used no coins but rods of gold bullion reckoned in '. Small change was made using half-catty pieces of molded salt, each reckoned as one-eightieth of a ' of pure gold. Under the Qing, it was officially known as Ningyuan Commandery but also continued to be referenced under the old name Jianchang. In the 19th century, it was the center of Sichuan's production of "white wax".
