Question

Is it true or false

Answer 1

As the knowledge you have, the best way to say Li Shiming is:

Li Shimin was one of the founders of the Tang Dynasty.

Answer 2

In fact, Li Shimin is not the founder of the Tang Dynasty. The founder of the Tang Dynasty was his father Li Yuan. Of course, in the war with the Sui Dynasty, Li Shimin made a tremendous contribution. The first emperor of the Tang Dynasty was Li Yuan.
