Why is Emperor Wu of the Han Dynasty the emperor with the strongest historical cohesion in China?

Because Emperor Wu of the Han Dynasty was very commendable in employing people, governing the country and formulating foreign strategic policies, he also created many historical firsts.

First, employment. He appoints people on their merits, recommends good people, and values people who give advice directly. No matter what status or position, you can take the exam and select talents through the exam, which can be said to have created a precedent for the imperial examination system. In addition, as long as there are talented people, no matter who they are, General Wei Qing was born as a slave, Queen Wei Zifu was selected from handmaiden, and historians Zhang Tang, Du Zhou and Yu Zhao were all selected from small officials, so there were many talents in the period of Emperor Wu of the Han Dynasty, which was also an important reason for the prosperity of the Western Han Dynasty.

Second, the pattern of governing the country is dominated by Confucianism, which is also a contention of a hundred schools of thought. According to the current social situation at that time, he conscientiously summed up his experience and thought that Confucianism was the guide to governing the country. So he started Confucian education and founded imperial academy. Imperial College in Han Dynasty was the first formal institution of higher learning founded by the government in the history of feudal society in China. It was established in Hanwu for more than two thousand years, and it is a bright pearl in the history of education in China.

Third, foreign strategy: open up the territory. During the period of Emperor Wu of the Han Dynasty, Xiongnu often invaded the border, and he moved a large number of immigrants to the northwest, which laid the foundation for his long-term battle. He sent generals Wei Qing and Li Guang to the hinterland of Xiongnu, reaching the foot of Yinshan Mountain. North to Le Lang and other four counties in North Korea; The southwest is located in seven counties in southwest Yi. Southeast appeases East Vietnam; Destroy South Vietnam in the south and establish Zhu Ya County in Hainan Island.

Especially in the northwest, the Silk Road was opened, and Zhang Qian made two missions to the western regions, introducing China's technologies of smelting iron, sinking wells, making silk and making lacquerware into the western regions. Pumpkins, carrots, grapes, blood horses, walnuts and gastrodia elata were also introduced into China, thus establishing friendly relations between the Western Han Dynasty and other countries in the Western Regions. This is of great historical significance. Have a far-reaching impact on future generations.

In addition, he set an example in many things, for example, he personally went to the Yellow River to harness the river, which moved the people very much.

So an outstanding and great emperor like him has a strong cohesion in history.
