Li Shimin is recognized as a great monarch in history, but I admire Emperor Kangxi even more. Although Li Shimin is an all-rounder in civil and military affairs, he can not only strategize, but also go into battle in person and lead troops to kill the enemy. However, his main enemies are all Han Chinese. After all, the war between them is just a civil war between his own people for power and interests. From the national point of view, his victory is only the selection of leaders within the country. Emperor Kangxi did not. When he sat on the throne of the emperor, he faced not only the threat of internal dignitaries, but more importantly, he had to deal with the anti-Qing wave of Han people. Compared with thousands of Han people in Qian Qian, Manchu people fell into the sand in the sea. In such a difficult situation, he showed his true colors as a hero. His strategy of governing Han people with Han people is still regarded as one of the greatest political means. Emperor Kangxi was brilliant and made great achievements in foreign countries. In addition to Ao Bai, Pingsan Francisco, recovering Taiwan Province Province and personal expedition to Gerdan, he realized the unification of China and reached the peak of the feudal society in China. His achievements are indelible, and what is more commendable is that he has been diligent and consistent all his life. In contrast, Tang Taizong, who was fatuous in his later years, seemed to lack stamina.
