What is the origin of the name Tianjin?

Tianjin was called Haijin Town, Zhigu Village and Tianjinwei in ancient times.

Tianjin's present position is an alluvial plain formed by sediment before the diversion of the ancient Yellow River. The ancient Yellow River diverted into the sea three times near Tianjin, near Ninghe County 3000 years ago, near Huanghua in the Western Han Dynasty and in the southern suburbs of Tianjin in the Northern Song Dynasty. During the Jin Dynasty, the Yellow River diverted southward, and the coastline of Tianjin was fixed. At the latest in the Warring States period, ancestors had already worked and lived here.

In the Western Han Dynasty, Emperor Wu set up a salt official in Wuqing. The opening of the Grand Canal in Sui Dynasty made the Sanchahekou at the intersection of the South Canal and the North Canal the earliest birthplace of Tianjin.

In the Tang Dynasty, a salt field was opened in Lutai and a salt warehouse was set up in Baodi. After the mid-Tang Dynasty, Tianjin became a land and water terminal for transporting grain from south to north. Haihe River used to be the boundary river between Song and Liao Dynasties, and it was divided into Song and Liao Dynasties in the north and south.

In the Song Dynasty, many military strongholds were set up in the south of Haihe River, such as Nanhe, Shawo and Liu Du, to prevent the Liao army from going south. The Jin Dynasty set up a military town "Zhigu Village" in Sanchakou, when streets were formed near the Tianhou Palace.

In Yuan Dynasty, after the opening of Cao Hai, zhi gu became a water transportation hub. Therefore, the reception hall and Linqing Wan Hu House were set up in zhi gu, and the granary and Tianhou Palace were built. 13 16, Haijin Town was established in Zhigu, which was then a military town and a grain transportation center.

Extended data:

Tianjin, which came from ancient times, was once a closed country. The Yellow River, with the highest sediment concentration in the world, entered the sea through Tianjin three times in history and deposited on the Tianjin Plain with amazing land-making ability.

Up to now, there are still some berms in ancient forests and other places in Tianjin. Archaeologists say these are the remains of the ancient coastline. The ancestors of Tianjin have thrived on this land and experienced countless historical opening and closing and changes of the times.

The origin of Tianjin's name began in the Ming Dynasty in China. After Zhu Yuanzhang, the founding emperor of the Ming Dynasty, ascended the throne, he divided his sons into kings and stationed them all over the country.

His fourth son, Judy, was made a prince and stationed in Peiping, which is now Beijing. After Zhu Yuanzhang's death, he passed it on to his eldest grandson Zhu Yunwen. In order to compete with Zhu Yunwen for the throne, Judy launched the Jingnan War in the history of China.
