What is the reincarnation of Li Shimin?

During his reign as emperor, Li Shimin never claimed that he was the reincarnation of stars and immortals. Li Shimin's descendants emperors did not claim that he was descended from domestic and foreign stars.

Judging from the ruling idea put forward by Li Shimin when he was emperor, the people are the most important, the monarch is the least, and the country is the second, which shows that he thinks he is also an ordinary mortal, not the reincarnation of the stars as described by charlatans.
