Introduction to the Yinping Ancient Road: The Yinping Ancient Road crosses many regions in Gansu and Sichuan. In ancient times, the starting point of the ancient road was called Yinping in Wen County, Gansu Province. During the Southern and Northern Dynasties, there was also the Yinping State, so it was called the Yinping Ancient Road. During the Three Kingdoms period, Deng Ai sneaked into Yinping and attacked Shu, making the ancient road more famous.
