If only one or two sons of Tang Gaozu call one of them by his first name, it is really meaningless to connect these names together. And Tang gaozu's earliest four sons happened to be named after these names, and their ambitions were exposed.
Tang Gaozu's eldest son is called Cheng Jian, which means Cheng Jian. The second son, Li Shimin, took the intention of saving the world and saving the people; Li Xuanba, the third son, is an interesting name, because in the Book of Changes, there is a saying that "heaven is mysterious and land is cultivated", and the meaning of Xuanba can be said to be very obvious. As for Tang Gaozu's fourth son, Li Yuanji, getting natural means everything will be fine.
Yuan Li
Among the founding emperors in ancient times, Li Yuan has always been despised by people. Don't compare with emperors like Zhu Yuanzhang and Liu Bang, even the founding emperors of those small countries are better than him. Why would anyone think that? This is mainly due to Tang Gaozu's own reasons, because Tang Gaozu's world depends on his sons. In the process of establishing Tang Dynasty by Li Yuan, his sons were closely related to Jinyang's existence in the world.
In other words, in the eyes of most history lovers, Li Yuan's establishment of the Tang Dynasty was not so much his own idea as just the right time. Many people think that without the help of several sons, I'm afraid Li Yuan could not have taken the first step against Sui. So, is this really the case? I'm afraid not. Tang Gaozu Tang Gaozu is definitely smarter than people think.
