When Emperor Wu of the Han Dynasty was building the Great Wall, he chose Yongji County in Yulin County, that is, the two counties of Pingxiang and Longzhou in Guangxi, and set up Yongji Pass to make the town south.
This Yongji Pass is the initial prototype of the Friendship Pass, which was later called "the important town in southern Xinjiang".
