Introduction to Wuchi Road: Wuchi Road was built in the Qin Dynasty and is the best preserved ancient post road with the most horse hoof prints. The remaining ancient road is about 350 meters long and five feet wide. Each stone step has different widths and heights. There are more than 200 horse hoof marks on the road. This road is an important passage from Sichuan to Yunnan, to Myanmar and India, the "Shu Shen Po Road" (the ancient Southwest Silk Road).
