Chongqing, Chongqing Municipality, China

Chongqing is situated at the transitional area between the Qinghai-Tibet Plateau and the plain on the middle and lower reaches of the Yangtze River in the sub-tropical climate zone often swept by moist monsoons. It often rains at night in late spring and early summer, and thus the city is famous for its "night rain in the Ba Mountains". The municipality reaches a maximum width of 470 kilometres (290 mi) from east to west, and a maximum length of 450 km (280 mi) from north to south. It borders the following provinces: Hubei in the east, Hunan in the southeast, Guizhou in the south, Sichuan in the west and northwest, and Shaanxi to the north in its northeast corner.
Chongqing covers a large area crisscrossed by rivers and mountains. The Daba Mountains stand in the north, the Wu Mountains in the east, the Wuling Mountains in the southeast, and the Dalou Mountains in the south. The whole area slopes down from north and south towards the Yangtze River valley, with sharp rises and falls. The area is featured by mountain and hills, with large sloping areas at different heights. Typical karst landscape is common in this area, and stone forests, numerous collections of peaks, limestone caves and valleys can be found in many places. The Yangtze River runs through the whole area from west to east, covering a course of 665 km (413 mi), cutting through the Wu Mountains at three places and forming the well-known Three Gorges: the Qutang, the Wuxia and the Xiling gorges. Coming from northwest and running through "the Jialing Lesser Three Gorges" of Libi, Wentang and Guanyin, the Jialing River joins the Yangtze in Chongqing.
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.
