Haihe River system consists of five main streams: South Canal, North Canal, Daqing River, Ziya River and Yongding River. In fact, this "nine rivers" doesn't really have nine rivers. In China's traditional concept, "nine" is the extreme number, that is, the largest number. Therefore, to sum up the tributaries of the Haihe River system and express them in one word means "nine".
"Three pontoons" and "two customs" are important fiscal and taxation departments of the government. At first, there was no iron bridge in Haihe River. In order to facilitate traffic, people set up pontoons. Because of its large scale, it is located in the north of Tianjin, also known as "Beidaguan". There is a ferry next to Beidaguan, called "North Wharf". This is the place where Judy, the prince of Yan in the Ming Dynasty, crossed the river when she launched the "Battle of Jingnan".
Tianjinwei at the bottom of Jiujiang, three pontoons and two passes. The ancients called it Haihe River, which is one of the seven rivers in China.
Extended data
Haihe River, also known as the ancient river, is the water of life and death in Tianjin. Standing at the top of the 4 15-meter-high Tianjin TV Tower overlooking the Haihe River, it is just a short blue line connecting Tianjin and Bohai Sea. It starts from Sancha River near Tianjin Jingang Bridge in the west and enters the Bohai Sea in the east. The main stream is only 74 kilometers long.
But it has five tributaries, and more than 300 tributaries extend in all directions, which constitutes the largest water system in North China-Haihe River System. The mainstream Haihe River is like the handle of a fan. North Canal, Yongding River, Daqing River, Ziya River, South Canal and other tributaries at all levels form a huge fan, spreading across the land of North China. Tianjin is the handle of this fan, only 34 meters above sea level.
The present elevation of Danjiangkou Dam, the water source of the middle route, is162m, which is more than150m higher than that of Tianjin, so the main canal of the middle route of South-to-North Water Transfer Project flows to North China from high to low. People say that Tianjin is located under nine rivers and is "the gateway to Kyrgyzstan when you are in Haihe River".
Overlooking the Acropolis, there are many tall buildings and lakes criss-crossing. The image of a modern city comes into our eyes, and we can feel the lingering between the city and the water, especially at night. The lights and water of the Acropolis complement each other and become colorful mud red, which is beautiful.
