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.
1399, Judy, the prince of Yan, led his army south, crossed the river from Sanchakou, Tianjin, and attacked Cangzhou. 1402, invaded Nanjing, the capital of the Ming dynasty, and ascended the throne of the emperor. After Judy acceded to the throne, she admired the Sanchahekou he passed when he fought in the world. He thought it was a treasure trove of geomantic omen and asked his minister to give them names. Finally, Judy chose the word "Tianjin", which means "the son of heaven crossed the land of Tianjin", hence the name Tianjin.
Soon, Judy moved to Beijing, Tianjin became the gateway of Beijing, and its military status became increasingly important. In the second year of Yongle in the Ming Dynasty (A.D. 1404), Wei was established in Tianjin, which was a military establishment of the Ming Dynasty. Tianjin * * * has three Wei Dynasties, with a strength of 1.6 million. Therefore, people also call Tianjin Tianjinwei. Building a city is building a city, and Tianjin, as a complete urban history, started from here.

Tianjin is called Tianjin for short, also known as Jingu and Jinmen. Tianjin began with the opening of the Grand Canal in Sui Dynasty. At the intersection of the South Canal and the North Canal, which is now the Sanchahekou of Jingang Bridge, it is known as the "Sanhui Haikou" in history and is the earliest birthplace of Tianjin. After the mid-Tang Dynasty, Tianjin became a land and water terminal for transporting grain from south to north. The Jin Dynasty set up "Zhigu Village" in Zhigu, and the Yuan Dynasty set up "Haijin Town", which was a military town and a water transportation center.
"Wei" is a military institution in the Ming Dynasty, under the command of the military governor and directly under the military governor's office. Although Wei's organizational system has no administrative authority, it has certain land (castles and wasteland reclamation), a large number of personnel (soldiers and military families who wasteland reclamation) and political affairs (military and political affairs and wasteland reclamation).
With the increase of population, the development of business and numerous affairs and disputes, the health center has been unable to manage this commercial city with mixed military and civilian. The Ming court set up officials, offices and schools in Tianjin, or moved foreign officials and offices to Tianjin as directors.
1949 after the founding of new China, Tianjin, as a municipality directly under the central government, has developed its economic construction and social undertakings in an all-round way, further consolidating its position as an important comprehensive industrial base and commercial center in China. Since the reform and opening up, Tianjin's port advantages have been continuously enhanced, and its foreign exchanges have been further expanded. In the new century, Tianjin has become a modern international port metropolis and an important economic center city in northern China.
