Yanjin Dou Sha Guan.

Dou Sha Guan, formerly known as Shi Men Guan, is located outside Dou Sha Guan Ancient Town in Yanjin County, Zhaotong City, Yunnan Province. It was built on the mountain and is strategically located. It sits on the highest point of the Five-Foot Road built in the Qin Dynasty. The Five-Foot Road was an important thoroughfare from Sichuan to Yunnan in ancient times, and Dou Sha Guan was the key to the Five-Foot Road. Stepping onto the Five-Foot Road, one can't help but feel the vicissitudes of history. The large bluestone mill is smooth and shiny, and the deepest horseshoe print is about 6-7 cm. For tourists, it is a nostalgic sightseeing road, and for locals, it is a shortcut connecting Dou Sha Guan Ancient Town and neighboring villages, which is used by schoolchildren and villagers every day. At different locations on the Five-Foot Road, one can see large cliff crevices on the steep cliffs on the opposite bank of the Guan River. The ancient Bo people placed stone coffins there to bury the dead, and there are still remains today. Looking down and up, the Five-Foot Road, river, railway, national highway, and expressway are all in the same frame, hidden among the lush mountains. Dou Sha Guan Ancient Town was damaged by an earthquake in 2006 and was fully restored in 2008, preserving and enhancing its ancient appearance. The prosperity of the tourism industry has brought new life to the ancient town. From Yanjin County, take the Mashui Line to Dou Sha Guan Ancient Town, 28 kilometers.
