The night view of Chongqing ranks first in the world. Among the widely recognized Beijing-Shanghai-Guangzhou-Chongqing ports, only Chongqing is mountainous, but it is mainly the night view of the islands on both sides of the sea and the Kowloon Peninsula. There are no bridges, while Chongqing is the intersection of Jialing and Yuzhong rivers of the Yangtze River, with many bridges. The upper reaches of the Yangtze River flow to the intersection of the two rivers and then to the lower reaches, with dozens of kilometers of coastline and twists and turns, which can be called Jiuqu 18 Bay. On both sides of the Yangtze River are Jiangbei District of Yuzhong District, Jiulongpo District, dadukou district, Banan District.
