On the one hand, Emperor Wu of the Han Dynasty adopted a policy of recuperation from the beginning to reduce the tax burden of the people, and then encouraged the development of agriculture and let the economy develop freely. Politically, the system is simplified, bureaucrats have multiple roles, and salaries are reduced. Diplomatically, he adopts a low-key and friendly policy, maintains good relations with most countries, and reduces the occurrence of wars.
At the same time, he was also an emperor with military talent and excellent military vision. He first annexed Korea to the east, then annexed Baiyue to the south, then marched into Dawan to the west, and finally defeated Xiongnu to the north. He achieved good results in all previous military campaigns, so he finally laid the basic scope of the Han Dynasty and created a prosperous situation of Hanwu.
On the other hand, he is very beautiful, especially when he often builds large palaces for his enjoyment. He went to Mount Tai many times to sacrifice to heaven, wasting people and money. At the same time, before he expanded his territory, the expenditure of the war troops was very large, which led to a deficit in the state treasury. In order to fill this hole, Emperor Wu of the Han Dynasty wanted to sell his official position, so he donated as much money as possible to the country to get any position. Although there is no real power, it leads to bureaucracy from top to bottom.
In this way, Emperor Wu of the Han Dynasty killed the goose that lays the golden eggs to gather wealth, and officials plundered the people, which led to the country becoming more and more corrupt and incompetent in economy, politics and diplomacy, the people being overwhelmed, refugees everywhere, and the population halved. That's why later generations have different views on what he did.
