Aerial photo taken on May 22, 2018 shows the Cloud Lake Holiday Resort in Guian New District in southwest China's Guizhou Province. As one of the country's pilot zones, Guian New District is a national demonstration area of inland opening-up economy. Guizhou is one of the least developed regions in China, but it has become a pioneer in big data in China due to its climate, power supply and network infrastructure. (Xinhua/Ou Dongqu)
