Mianning County is located in the northern part of Anning River Valley, with mild climate and rich products, which is suitable for human survival. According to the bronzes, pottery and stone tools excavated in the county, at least in the late Bronze Age from the spring and Autumn period to the Warring States period 206 years ago, the residents of this area had large tribal groups, and some of them had entered the farming society.

In the sixth year of Yuanguang (129 BC), Emperor Wu of the Han Dynasty sent Sima Xiangru to decide Xiyi. The leaders of Qiong, Zuo, ran, Si and Yu were all invited as ministers. The boundary of Han Dynasty extends to Mo and Ruoshui in the West. Today, the southeast of Mianning County is a part of Qiong at that time, and the northwest is a part of Zuo.
