Why did Zhu Di send troops to conquer Vietnam, which was called the biggest war boasted by cowhide in history?

The Ming Dynasty was the largest dynasty in China in history. After the establishment of the Ming Dynasty, the army of the Ming Dynasty attacked the city slightly, which further expanded the territory of China. At that time, Vietnam, as a subordinate country of China, claimed the territory of China and refused to pay tribute to China, which made the Ming Emperor Zhu Di very angry, so he declared war on Vietnam.

This war is also known as the biggest braggart war in the world. At that time, the Ming Emperor Zhu Di claimed that he had sent 8, troops, while the Vietnamese Emperor even exaggerated that he had sent 7 million troops. As a result, both sides were particularly embarrassed when the two armies met. Because in the actual war, the two sides sent less than 1 thousand troops.

This embarrassed the commanders of both sides, so the war ended in nothing, and the history books recorded it as a joke. In fact, the Ming dynasty at that time was very powerful and fully capable of destroying a small country like Vietnam. However, the Ming dynasty at that time did not intend to destroy such a country, but let them learn a lesson. After this war, the dispute between Vietnam and the Ming dynasty was over.

In fact, many wars in history exaggerate numbers, so as to show one's military power and make opponents feel scared. Moreover, this method can also deal a better blow to the enemy's morale before the war. However, the war between the Ming Dynasty and Vietnam was so boastful that even today it is still a figure that ordinary people can't understand. It is no wonder that it will be recorded as a joke by historians and become the talk of everyone after dinner.
