This is because the examples given by everyone are all wars fought by the north against the south, and the north won. But in fact, there are not a few wars between the south and the north, but everyone didn't pay attention. Many times, fighting in the north and fighting in the south is won by the southern base.

First, many reasons for the victory of the Civil War are based on the fact that the North is based on the South.

If nothing else, let's talk about the establishment of Liu Bang, Emperor Gaozu and the Han Dynasty. How did Liu Bang establish the Han Dynasty? Liu bang crouched in Bashu, waiting for the opportunity. Where is the land of Bashu? Bashu is in the south. It was because Liu Bangxian had the land of Bashu as a base that he slowly developed and grew up. If Liu Bang hadn't sneaked into Chencang, the land of Bashu, how could he have a chance to win the world in the Central Plains!

And this incident indirectly proves that the so-called north-south struggle is just that some people can't see the situation clearly. Whether the Han Dynasty was established in the north or the south obviously seems to be inextricably linked. Liu Bangxian occupied Bashu, then marched into Guanzhong, and began to conquer the world in the East.

Second, many times it is not a dispute between North and South, and the criteria for judging North and South are different.

Let's talk about the Three Kingdoms period. In fact, it is very slow to distinguish between south and north or north and south during the Three Kingdoms period. If Cao Cao attacked Liu Bei, it was really a dispute between the North and the South, but there were times when the South fought against the North! As the final winner of the Three Kingdoms, Wei was once attacked. Wu and Shu joined forces to fight against Cao Wei, and Zhuge Liang led troops to the northern expedition several times!

Zhuge Liang led troops to the Northern Expedition, but if it was not for the major mistakes in decision-making and the failure of talented generals, the strategy of fighting in the south and the north would not have failed. Besides, Zhuge Liang's northern expedition, Wei's soldiers also won and lost, and Wei did not really win.

The Ming Dynasty really lost to the North, and the Ming Dynasty became the winner. Therefore, there are not only south to north in history, but also north to south. There is no saying that any kind of play is sure to win.
