We know that the Yangtze River originates from the Tanggula Mountains on the Tibetan Plateau, the roof of the world, flows through 11 provincial administrative regions, and then flows into the East China Sea east of Chongming Island in Shanghai. With the Yangtze River estuary, Shanghai has taken advantage of its unique geographical advantages to develop port trade and gradually developed into an international metropolis known as the "Pearl of the Orient". As early as the Tang and Song Dynasties, Qinglong Town in Shanghai had become a well-known estuary seaport, developing maritime trade as far away as Japan and as close as Taizhou and Wenzhou. During the Song Dynasty, the imperial court also established a municipal shipping agency in Qinglong Town, which could receive more than 15,000 yuan in commercial taxes every year. Qinglong Town, with its many shops and merchants, has become the most developed market town in Shanghai.
