Why did the Han Dynasty have such a strong desire to conquer the outside world

Looking at the history of China, it is not difficult to find that although our country has a history of 5000 years and often changes dynasties, most of them are internal fights. The territory they fight for is the Central Plains, and the desire to conquer is not very strong. For example, after the founding of the Ming Dynasty, Zhu Yuanzhang listed a series of commandments in Huangming Zuxun, which were used to warn future generations against wanton expedition. The reason is that "the land is not enough to supply, and the people are not enough to command."

Of course, for a large agricultural country or a farming nation, it is too costly to launch a expedition in areas that are not suitable for farming, and the gain is not worth the loss. It is just a futile loss of soldiers' blood. However, there was a dynasty in which he had a strong desire to conquer the outside world. This dynasty was the Han Dynasty, especially in the period of Emperor Wu of the Han Dynasty. He attacked Xiongnu in the north, reached the western regions in the west, exterminated Korea in the East, and joined Baiyue in the South. Because the Xiongnu often harassed the border, he sent troops to fight directly, and drove the Xiongnu out of the grassland in several generations Chen Tang also sent troops to the Xiongnu, captured the Xiongnu camp, killed zhizhidanyu, and left behind such heroic words as "if the Ming Dynasty committed crimes against the strong men, they would be punished even if they were far away".

Why is the Han Dynasty's desire to conquer the outside world so strong? Let's talk about the official title system of the Han Dynasty. The Han Dynasty basically continued the system of the Qin Dynasty. In order to stimulate the blood of the soldiers, the Qin Dynasty used officials to promise that whoever killed more enemies would be able to confiscate the land. After Liu Bang became emperor, he once made such an oath as "not Liu's family, not king, not meritorious" The Xiongnu attracted the attention of the generals of the Han Dynasty. It can be said that the Xiongnu just hit the muzzle of the gun. No matter Chen Tangjiao attacked Xiongnu, or ban Chao, a famous historian in the Eastern Han Dynasty, he was unwilling to copy documents and join the army. With Dou Gu's attack on the northern Xiongnu, he made great contributions. Of course, there was a passion to die for his country, but it more clearly reflected the strong desire of Han Dynasty people to make contributions.

Of course, it can also be considered that the people of the Han Dynasty had enough to eat. After the establishment of the Han Dynasty, after the first emperor of Qin unified a series of standards such as national weights and measures, the strength of the Han Dynasty reached unprecedented prosperity. Under the conditions of excellent weapons, strong military advantage, and sufficient food and grass, the officers and men of the Han Dynasty had nothing to do but train or train, but they could not launch a war against other nationalities for no reason Warfare. In that sentence, when the Huns hit the muzzle of the gun, you said that you didn't know where the gap between you and the Han Dynasty was. If you didn't have to harass the Han Dynasty, you were directly driven out of the grassland of Mobei by the Han Dynasty, which made the territory of the Han Dynasty extremely vast.
