Did Tianjin immigrate from Anhui? Is there any historical basis?

Why is this big city called Tianjin?

In the early years of Qing Qianlong, Wang Ling, a poet who came to Tianjin from Jianjiang, wrote the first Zhi Zhu Ci describing Tianjin folk customs. The poem says: "Tianjin is named after Changling." Changling refers to the Ming emperor Judy buried in the Ming Tombs. Tianjin was named in the second year of his reign (Yongle II, AD 1404). At that time, it was not named after a place name, but after a military establishment. It was Tianjin Wei.

Judy is the son of Zhu Yuanzhang, the founding emperor of the Ming Dynasty. When Zhu Yuanzhang was emperor, in order to consolidate the influence of Zhujiajia, he divided China's land into plots for his next generation, which was called "Fenfan". Every piece of land in China is under the jurisdiction of his Zhu family. Originally, he was afraid that people with other surnames would rise up against Zhujiajian and take the throne of Zhujiajian. I didn't expect the relatives of Zhujiajian to rise up and fight for power and power. Judy was made a prince in Peiping (now Beijing). He secretly expanded his clothes and strengthened his power. After Zhu Yuanzhang's death, he did not pass the throne to his son, but to his grandson Zhu Chonglian (Wen Jian). Judy, the prince of Yan, is ambitious. He was not satisfied with his nephew being emperor, so he wanted to overthrow Zhu Chonglian himself. Zhu Yunwen and his ministers are also ready. Seeing that these princes are ambitious, they try their best to weaken their strength and power. This is the so-called "cutting vassals". Yan took the lead in resisting the emperor at that time and resisted by force, calling himself "Jing Nan".

Judy sent troops from Beijing, successfully crossed the river in zhi gu, and captured Cangzhou (zhi gu is the old name of Tianjin, and it is said that crossing the river was chosen in this North Pass), and then led troops to capture Nanjing (the capital of the early Ming Dynasty was in Nanjing), when all the rebels were pacified. Judy, the prince of Yan, became emperor herself. The Prince of Yan established his capital in today's Beijing, and gradually built the Forbidden City in Beijing. Judy, the prince of Yan, became Emperor Yongle. Thinking that Tianjin (then called zhi gu) was a military important place with both sea and inland river, I wanted to send troops to zhi gu to farm and guard. Recalling the successful crossing of the river in Zhigu and the establishment of Tianjinwei. Wei means safe community, with 5600 people per Wei. "Tianjin" means ferry. Emperor Yongle thought it was the "Tianjin Beam of the Son of Heaven", that is, the ferry of the emperor. After crossing this ferry, the road is ahead.

At present, Tianjin History Museum also has a collection of "Building the Monument of Sanguan Temple". The inscription says "will help Cangzhou", which refers to Judy's experience and explains the origin of Tianjin's name.
