The Anning River Basin is located in the northern part of China's Sichuan-Yunnan Copper Belt. The abundant copper resources there are just connected with Yandao copper mountain, which making the Lingguan Road on the north line of Southwest Silk Road become a copper belt. This feature should not be a coincidence, but the reason why the copper resources themselves can provide necessary resources for the ancestors' migration at both ends of the road. Based on this, the expansion of the development of the copper industry in the Anning River area has also contributed to the connection of Lingguan Road on the north line and the Wuchi Road on the south line of the Southwest Silk Road，which further integrated the southwestern border areas across the Jinsha River, as well as laid a foundation for the consistency of certain civilizations of the Southwestern Minority Groups for Han Dynasty. The copper industry represented by Qiongdu south mountain copper mountain and Lingguan Road mountain in Anning River area of the two Han Dynasties was used to develop and consolidate the southwest border, making it initially melted into the Chinese civilization and providing important resources and financial protection.
