On Ruoergai grassland, where the Red Army marched during the Long March, young Tibetan woman Ngorcog works as a licensed drone pilot. Once relying on horses and trucks, the plateau now taps the low-altitude economy. Drones deliver emergency supplies during disasters, monitor grassland ecology and support tourism. Local Tibetan female pilots are trained, and drone courses are offered to schoolchildren, planting seeds of modern technology on the historic land.
