The given surname has existed since the time of the five emperors. The emperor gave a surname to the minister who made great contributions. This is the honor of the minister and can also benefit from it. For example, Jiang Bin in the Ming Dynasty was given the surname by the emperor? Zhu? This is the royal family name. This shows that the emperor trusts him and regards him as his family, which is naturally beneficial to him. Let's look at Li Shimin. Li Shimin's father is Tang Gaozu. According to historical records, Xiao Ye was given by Emperor Gong of the Western Wei Dynasty who acceded to the throne in 554 AD before his birth!
From this point of view, Li Shimin was not born in that year, and his father Li Yuan was only 12 years old. Some people say that this surname was given to Li Shimin's great-grandfather Ye Li, but in fact. Ye Li is dead. Therefore, at that time, Xiao Ye's surname was given to Li Shimin's grandfather, Li Fang, Tang Gaozu's father! From then on, Liu Yun in the history books became Xiao Ye Cloud, while Tang Yuan became Xiao Ye Yuan.
When Emperor Wendi of Sui Dynasty became Pu, he always wanted to restore his China surname. Finally, after the death of Yu Wenyun. Liu Pu Rujian got the opportunity to help Yu Wenchan, then 6-year-old Zhou Jingdi. Pruliujian took this opportunity to restore the surname of the Han aristocrat. Liu Rujian changed back to Emperor Wendi of Sui Dynasty. Xiao Ye also changed back to Tang Gaozu. The year was 579 AD! In 579 AD, Li Shimin was not born! Therefore, the Li family named Xiao Ye. Li Shimin did not attend. His original name is Li Shimin, and he has always been Li Shimin!
