Why did the Tang emperor call Taiyuan "the land of Longxing"?

The reason why the emperors of the Tang Dynasty called Taiyuan "the land of Longxing" was mainly because there were many emperors in Taiyuan.

First of all, Li Yuan, the founding emperor of the Tang Dynasty, set out from Taiyuan to conquer the world. Tang gaozu was appointed by Yang Di to stay in Jinyang (Taiyuan). After Yang Di was trapped in Yangzhou and killed by Yu Wenhuaji, there was chaos in the Sui Dynasty. Li Yuan who stayed in Jinyang set out from Taiyuan. With the help of generals such as Li and Li Yuanji, he finally invaded Luoyang and made his grandson Emperor Yangdi, while the real power fell into the hands of Prime Minister Tang Yuan. Li Yuan later forced the little emperor to meditate, established the Tang Dynasty, and became the founding emperor of the Tang Dynasty, namely Tang Gaozu.

? Li Yuan has many sons, of which Li Shimin is the most successful. Li Shimin, the second son of Li Yuan, made great contributions to the establishment of the Tang Dynasty. He was made King of Jin to govern Taiyuan. Manage Taiyuan and compete with Prince Li for inheritance rights. Later, in the change of Xuanwu Gate, Li Shimin killed Prince Li and Li Yuanji, and successfully became the second emperor of the Tang Dynasty, namely Emperor Taizong. Emperor Taizong was a wise king. Under his rule, the country was rich and the people were safe, creating a "rule of chastity."

? Li Zhi, the third emperor of the Tang Dynasty, was named King of Jin by Emperor Taizong at first, and Li Zhi was the seventh son of Emperor Taizong and Li Shimin. However, as if by God's arrangement, Li Zhi, King of Jin, succeeded in becoming the third emperor of the Tang Dynasty.

? Wu Zetian is also from Taiyuan, and once worked as a queen.

? Li Longji, the emperor of the Tang Dynasty, was also called the King of Jin, and later became the sixth emperor of the Tang Dynasty, namely Emperor Xuanzong of the Tang Dynasty. Xuanzong of the Tang Dynasty made great efforts to govern and created the prosperous time of the Tang Dynasty-Kaiyuan. He was a very successful emperor in the Tang Dynasty, and he and Emperor Taizong Li Shimin were wise kings in the Tang Dynasty.

It is precisely because most of the emperors of the Tang Dynasty came from Taiyuan that the emperors of the Tang Dynasty called Taiyuan "the land of Longxing".

? Yang Di, the second emperor of Sui Dynasty, was also awarded the title of King of Jin before he became a prince. Later, the king and the Prince competed for the right of inheritance, and Prince Yong Yang was abolished. Yang Guang became a prince and successfully became the second emperor of the Sui Dynasty.
