I think Li Shimin was one of the best emperors in ancient China. When he was eighteen, there was a local official. When he first met Li Shimin, he said that his country was "an enlightened person, and SHEN WOO was like Wei Wu". Look, Li is talented at such a young age. Mao Zedong commented on Li Shimin: Since ancient times, you can't be the son of Emperor Taizong. At the age of 20, he rebelled with his father in Taiyuan. 1 year, captured Chang 'an and established the Tang Dynasty. In the following seven years, the Tang Dynasty launched six great battles to unify China, and Li Shimin personally commanded four times, with outstanding achievements. His military talent and fighting courage, not to mention the emperor, are no less than those of famous soldiers in previous dynasties! Tang Taizong was not only a politician, but also a poet and calligrapher. The reason why poetry and calligraphy in the Tang Dynasty have such a high historical position and reached the peak of China culture is directly related to Li Shimin! Li Shimin respects Confucianism, Taoism and Buddhism, and even allows Nestorianism to enter China. He studied history, legislated, created the imperial examination, established the system of equal land and the system of three provinces and six arrests, which set a model of political system for later dynasties. From the perspective of personal ability, Li Shimin is worthy of the word "all-rounder". Since the Qin Dynasty, no emperor has been so comprehensive and excellent.
