Chongqing, Chongqing Municipality, China

The central urban area of Chongqing, or Chongqing proper, is a city of unique features. Built on mountains and partially surrounded by the Yangtze and Jialing rivers, it is known as a "mountain city" and a "city on rivers". The night scene of the city is very illuminated, with millions of lights and their reflection on the rivers. With its special topographical features, Chongqing has the unique scenery of mountains, rivers, forests, springs, waterfalls, gorges, and caves. Li Bai, a famous poet of the Tang Dynasty, was inspired by the natural scenery and wrote this epigram.
Specifically, the central urban area is located on a huge folding area (similar to the landscape of Appalachian Mountain in USA), and the Yuzhong District, Nan'an District, Shapingba District and Jiangbei District are located right on a big syncline. And the Southern Mountain of Chongqing (Tongluo Mountain) and the Zhongliang Mountain are two anticlines next to the syncline of downtown.
