Generations of bridge builders create various engineering miracles in Guizhou since China's reform, opening-up

Aerial photo taken on Aug. 21, 2018 shows the Gejing Bridge, built in the Ming Dynasty (1368-1644), in Fuquan, southwest China's Guizhou Province. In southwest China's Guizhou Province, where endless karst hills dominate the land, modern transportation is made possible thanks to more than 20,000 bridges that cross over the valleys. The province easily justifies itself as a museum of bridges: among the world's 100 highest bridges, 46 are located in Guizhou. Over the four decades since China's reform and opening-up, generations of bridge builders have created various engineering miracles while battling technological challenges on tricky terrains.
