The Western Han Empire in the period of Emperor Wudi was the most powerful country in the world at that time, and it was also a relatively strong period in the history of China. There has been a saying that "the Han and Tang Dynasties flourished". The "Han" here mainly refers to the period of Emperor Wu of the Han Dynasty. People often compare Emperor Wu of the Han Dynasty with Qin Shihuang, because China's feudal autocratic centralized state was established by Qin Shihuang and consolidated by Emperor Wu of the Han Dynasty. During his 54 years in office, he implemented many new measures, which brought unprecedented prosperity to the Western Han Dynasty.

Liu Che, son of Emperor Jing of Han Dynasty and great-grandson of Emperor Gaozu, was born in Yunnan in 156 BC. At the age of 7, he was made a prince and 16 became an emperor. Although Emperor Wu of the Han Dynasty was still very young when he ascended the throne, he had a set of methods to govern the country. Shortly after he acceded to the throne, he issued an imperial edict, asking the prime minister, the censor, the county magistrate, the vassal king and others to recommend virtuous and upright people. In the form of imperial edict, many scholars were elected in various places, and more than 100 people were selected and sent to the central government. Emperor Wu of the Han Dynasty personally questioned their way of governing the country and ensuring peace. One of them, Dong Zhongshu, put forward in "Countermeasures" that "anyone who is not a subject of six arts, Confucius' skills, are all unique, so he does not advance." "This kind of claim coincides with the desire of Emperor Wu of Han Dynasty to unify the whole country. So Emperor Wu of the Han Dynasty praised it, and Prime Minister Wei Wan also wrote a letter to Emperor Wu of the Han Dynasty, pointing out that virtuous and upright people sent from all over the country, some were legalists, some were strategists, etc., and these people not only failed to govern the country well, but also had their own opinions, which would disturb the court and were not suitable for use. Emperor Wu of the Han Dynasty accepted the suggestions of Dong Zhongshu and Wei Wan, and only retained some Confucianism such as Gong and others, and the rest were not appointed. This is the famous "Mohist school worships Confucianism alone" in history. Since then, Confucianism, as the ruling ideology of feudal society, has had a far-reaching impact on the whole feudal society.

Emperor Wu of the Han Dynasty was also keen and decisive in solving the whole social problems. He knows that to realize his political ambition, he must first increase production and enhance his economic ability. On the one hand, he stabilized the individual peasant economy and announced the policy of "emphasizing the foundation and neglecting the end"; On the other hand, it restricts the merger and illegal behavior of landlords. At the same time, he also paid attention to water conservancy construction, and successively built channels such as river diversion, Fen diversion and oblique diversion into Weihe River, which enabled shipping and irrigation of fields. In the 20 years after he ascended the throne, he carried out new fiscal policy and new economic policy; Organize the monetary system and directly control the casting and issuance of money; Scrap and sell all kinds of inferior copper coins, and uniformly implement "five baht". Implement salt and iron official camp and set up salt and iron officials. Control the big industries and big businesses that are related to the lifeline of the economy. The implementation of these policies enriched the finance of the Han Dynasty.

Because centralization has been greatly strengthened, the country's economic strength has never been stronger. In order to ensure the production and people's life in the northern border areas, Emperor Wu of Han Dynasty decided to change the new peace policy towards Xiongnu since the early Han Dynasty and launched wars against Xiongnu, which were launched three times in BC 127, BC 1265438 and BC 19. These three campaigns all achieved decisive victories, dealt a fatal blow to the Xiongnu nobles, basically solved the threat of Xiongnu, and ensured the people in the frontier to live and work in peace and contentment. However, these wars consumed the wealth of the country, increased the suffering of the broad masses of people and paid a huge price. In order to unite the western regions and resist the Huns, he sent Zhang Qian to the western regions twice to communicate with them, which opened up the "Silk Road" and opened up a new era of cultural and product exchanges between the Central Plains and the western regions. It not only promotes the development of economy and production in all parts of Asia, but also promotes the connection between Europe and Asia.
