In ancient China, it was generally said that the expedition to the east, the expedition to the west and the expedition to the south, but why should the Northern Expedition be used in the north?

The origin of the word "cutting" can be traced back to the famous King Wu, who attacked from west to east, which was called King Wu's cutting in history. The word crusade involves the difference between subject and object for a period of time. Generally speaking, crusaders are guests, and crusaders generally brag. In the ancient history of China, the northern Central Plains was in a dominant position for a long time, and many dynasties centered on the north. So the north generally says "logging".

On the contrary, as a part of the imperial court, the south is usually controlled by the north. However, because the south is far away from the Central Plains, there are many indigenous people and local separatist forces in the south. Feudal dynasty, southern turmoil. The north will send troops to the south. This kind of military action is usually called the southern expedition. There are too many examples of the southern expedition, which have existed in almost all dynasties, such as the famous Zhuge Liang southern expedition.

Only the Northern Expedition is more impressive, and almost every Northern Expedition has been written into the history books. In ancient history, the advantage of the north over the south has a long history. Throughout the ancient history of China, the only successful Northern Expedition was Zhu Yuanzhang's expulsion of Yuan Shundi. In the history of dynasty change, the north has advantages, but with the decline of dynasties, the advantages of the north are no longer obvious. There are also many powerful dynasties in the south. In order to compete for the control of the Central Plains, they will play the banner of the Northern Expedition. There is no way to do this!

This is the formation reason and historical basis of ancient northern and southern expeditions in China. We know that after Zulu's Northern Expedition, the north fell into the control of the Hu people. During the Western Jin Dynasty, many people immigrated to the south. People who come to the south of the Yangtze River always want to restore the Central Plains, and often lead troops to cross the river for the Northern Expedition. For example, Judy's northern expedition, but the northern expedition is generally difficult to succeed.
