Aerial panorama photo taken on May 22, 2018 shows a tea plantation tourist spot 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/Cai Yang)
