"24 turn" Panshan Highway 1927. It is a 24-bend highway, which was called elegant in ancient times and semi-pass by locals. Located in the southern suburb of Qinglong County, Guizhou Province, 1 km. It is a winding mountain bend made by cutting a road at the entrance of the post station of Guyaguan in Qinglong County. It is about 4 kilometers long, and each turn is only a few tens of meters long. Every turn is a 360-degree "turn back", hovering between the majestic and steep Jinglong Mountain and Mopan Mountain. During the Jiajing period of the Ming Dynasty, the poet Zhou Wenhua passed by, leaving a poem "The wind is high and the mountains are high, but it is difficult to accumulate horseshoes in the middle of the clouds". One is to save clothes and land, and it is to lock keys. "
