When many people start to look at history, they will have a doubt, that is, they do not know how important this "Yanyun Sixteen Prefectures" is to the Central Plains. Because many history books have records, it is precisely because of this Yanyun Sixteen Prefectures that the Song Dynasty has been constrained by the northern countries. But because of this, Zhu Yuanzhang's recovery of Yanyun for sixteen weeks would become even more powerful, and it only took him one year to recover this hard bone that the Song Dynasty could not chew down for more than three hundred years.
But does the land also recognize its owner? Obviously this is not the case, and since the land is there, there must be a way to recover it. However, the difference between the Song and Ming dynasties was still very large, one of which was that the emperor's ideology influenced the decisions of the dynasty. After the Song Dynasty destroyed the Northern Han Dynasty, the area south of youyun Sixteen Prefectures was unified, and the country tended to be stable and content with the status quo. However, because Song Taizu himself was "yellow robe plus body", he was always wary of his own martial generals, afraid that they would establish martial arts.
In fact, Han, Tang, Song, and early Ming did not control the Youyun area, but only Song never took it, because Song's strategy was wrong at the beginning, song military strength at its peak did not go first, but to fight the isolated city of Taiyuan, a dozen years, although taiyuan was taken, but consumed too much national strength, and the northern nomads used this time to strengthen their strength, an increase and a decrease led to Song has been in the ascendant, but also for the later subjugation of the country to lay the biggest curse.
The second is that the two sides face different enemies. The Song Dynasty faced the Liao State, and the Ming Dynasty faced the end of the Yuan Dynasty, which is certainly incomparable. At that time, the Liao army was strong and strong, the interior was stable, and it had the combat strength of the Northern Han Dynasty, and the geographical advantages of the north and northeast were favorable. At the end of the Yuan Dynasty, the combat strength of the soldiers and horses declined, and there were internal problems, and several other forces, such as Chen Youyu, were all anti-Yuan. In short, in the face of the objective situation of the Northern Expedition, those who were generals certainly considered more.
The most important point is that the Ming Dynasty and the Song Dynasty, their fundamental situation is also different. After nearly a century of rule over China by the Yuan Dynasty, the ruling class of the Yuan Dynasty set up horse farms throughout the country, which was an important force for building cavalry. The horses of the Song Dynasty were all in Yanyun Sixteen, which led to the initial lack of combat effectiveness of the army. Moreover, the Song Dynasty's strategy of emphasizing literature over military force also led to their own inability to cultivate a strong cavalry team
The Central Plains Dynasty had actually been thinking about how to fight against the cavalry of the northern nomads. In the Ming Dynasty, there were several people who found the correct answer, one was Zhu Yuanzhang, one was Zhu Di, and the other was Li Chengliang and Yuan Chonghuan. The answer they found, and the right thing to do in practice, was to build a more powerful cavalry. Therefore, the Song Dynasty lacked this innate advantage at the beginning, which can be said to be directly pinned down by the enemy.
During the Yuan Dynasty, the whole country raised horses, and Zhu Yuanzhang was able to organize powerful cavalry. There are also several canals that were repaired during the Yuan Dynasty. After Zhu Yuanzhang defeated Chen Youyu and Zhang Shicheng, he ruled over all the rich lands in the south, and the people, horses, money and grain were in their hands. After the Yuan court lost the two lakes, the money and grain could not keep up. War is fought with money and food. Although the Northern Song Dynasty ruled Shandong, Shanxi and part of Hebei, it also had money and grain, but it lacked horses, and the Liao state was in its prime, so it was normal to fight. The two Song Dynasties could not fight head-on, and the economic war was fought in a mysterious way, but unfortunately the economy could not hit the national territory.
