The photo taken on May 25, 2014 shows the Danxia landform of Zhangye city in northwest China's Gansu Province. The unusual shapes and gorgeous colors show the stunning power of nature. Ancient Zhangye, originally called Ganzhou, was an important city on the ancient Silk Road. Now the Zhangye government plans to turn the city into a great place to live and travel.
