According to the Anthology of Taizong in the Two Tang Dynasties, when Li Shimin was four years old, he met a physiognomist on an outing with his father Li Yuan. The physiognomist first praised Li Yuan as a noble man and then praised the people of the world, saying that he "Anyone who is twenty years old will be able to help the world and bring peace to the people." After Li Yuan searched for the fortune teller but could not find it, he changed his name to Li Shimin (that is, Li Shimin's real name may not be Li Shimin).
It can be seen that Li Shimin was not called by this name originally, but there is no record in the history books of what he was called before he was called Shimin. This is probably because he was destined to help the world and bring peace to the people, so he should have deliberately concealed his real name. . The eldest brother Li Jiancheng, the third brother Li Yuanba, and the fourth brother Li Yuanji, I don’t know how Li Yuan got their names. The eldest brother, the second brother, the third brother, and the fourth brother are not in the same row.
A good name will unintentionally play a positive, healthy, energetic and promising role in people. Maybe it was a story compiled to show that Li Shimin was the proud man of heaven, or maybe there was something wrong with it. In short, this good name really allowed him to climb to the highest position of power in feudal society, and became a wise king and holy lord. Compared with the effect of changing his name, it can be said that there is no greater benefit.
