Cloud computing industry new icon of Zhongwei City in NW China's Ningxia

Aerial photo taken on June 26, 2018 shows the Baotou-Lanzhou railway in Zhongwei City, northwest China's Ningxia Hui Autonomous Region. Located at the southern border of the Tengger Desert, Zhongwei City was noted for using straw "checkerboards" to stop desert encroachment six decades ago when the Baotou-Lanzhou Railway, China's first desert railway, passed through Tengger near Shapotou of the city. By far, the desert city is developing cloud computing industry, which has become a new icon of the city. (Xinhua/Wang Peng)
