Wuchi Road was built by China during the Warring States Period to connect the Central Plains, Sichuan and Yunnan. Li Bing, the prefect of Shu County, Qin State, used the primitive method of accumulating wages and burning stones to cut mountains and dig wells, which opened up this road.

Because the road is five feet wide, it is called "five-foot road".

The proposal of the "Southern Silk Road" is based on Sichuan, which is distributed in Yunnan, Myanmar and India, and a large number of similar cultural factors have been discovered. These cultural factors include not only Sichuan culture, but also a large number of cultural factors in India and even West Asia, which predated the Silk Road which left the western regions through the northwest of China. Because the Silk Road, as a symbol of ancient cultural exchanges between China and the West, has been generally accepted by Chinese and foreign scholars, it is called the "Southern Silk Road" (hereinafter referred to as the "Southern Silk Road"), starting from Sichuan and passing through Yunnan to Myanmar, India and Pakistan to Central and Western Asia.
