Zhu Di was the son of Zhu Yuanzhang, the founder of the Ming Dynasty, and after the early death of the crown prince, Zhu Di was once considered the future heir of the Ming Dynasty. However, Zhu Yuanzhang's final decision surprised everyone, and he chose to pass the throne directly to his grandson Zhu Yunjiao. This move caused dissatisfaction among Zhu Di, the King of Yan, and later directly rebelled and regained the throne. Zhu Di passed through a small town when he raised his army, changed its domineering name to it, and now becomes a first-tier city.
This place is today's Tianjin, and the source of the name Tianjin is Zhu Di. Zhu Di was appointed by Zhu Yuanzhang to garrison Yandi, so he was known as the King of Yan, and was the most capable of Zhu Yuanzhang's sons. Zhu Yuanzhang once praised Zhu Di as the most like himself of all his sons. Although Zhu Yuanzhang liked Zhu Di, he did not think that Zhu Di was a qualified emperor, because at this time the world was already too peaceful, and he needed a benevolent emperor to preside over the overall situation, and Zhu Di lacked such benevolence in his personality.
After Zhu Yuanzhang's death, Zhu Di disobeyed Zhu Yunjiao, rebelled, he led a large army from Yandi to Nanjing, passing through this place in Tianjin in the middle, he thought this place was good, so he gave this place a name called Tianjin, heaven is the meaning of tianzi, at this time Zhu Di has thought that the throne is within reach, and this time there is a clear record of 1400 years, this year, on the map of China, there is the name Tianjin.
And this name did give Zhu Di good luck, he successfully seized the throne and became the third emperor of the Ming Dynasty. The name Tianjin has also been used, and during the Qing Dynasty, Tianjin was known as Tianjin Prefecture and was an important treaty port. After the founding of the People's Republic of China, Tianjin was assigned to Hebei Province, but it was later found that this was not conducive to administration, and Tianjin was set up as a municipality directly under the central government. Tianjin is a city with a deep history and is one of the most important cities in China.
