Introduction to the origin of Tianjin's name

1. The name of Tianjin was named by a prominent king (Zhu Di) in the Ming Dynasty.

2. 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, Zhu Di, was made a prince and stationed in Beiping, which is now Beijing. After Zhu Yuanzhang died, he passed on to his eldest grandson Zhu Yun. In 1399, Zhu Di, the prince of Yan, led his army south, crossed the river from Sanchakou, Tianjin and attacked Cangzhou. In 142, he invaded Nanjing, the capital of the Ming Dynasty, and ascended the throne of the Emperor. After Zhu Di ascended the throne, he was very appreciative of the Sanchahekou, which he passed when he was fighting for the world. He thought it was a treasure trove of geomantic omen and asked his ministers to give their names. Finally, Zhu Di chose the word "Tianjin", which means "the land where the son of heaven crossed Tianjin", hence the name Tianjin.
