Since ancient times, this place has been a place where soldiers have fought, changed the history of the Song Dynasty, and was later recovered by Zhu Yuanzhang himself
The Song Dynasty can be regarded as a very strange dynasty in Chinese history, if it is economic and cultural, the Song Dynasty can be regarded as one of the best in all dynasties, but when it comes to military, everyone will think of the title of "Big Instigation". It is true that in history, the military strength of the Song Dynasty was indeed worse than that of the Liao or Jin States of the same period as his, but we may overlook the fact that the Song Dynasty was established under the premise of losing the Sixteen Prefectures of Yanyun. So where are the Sixteen Prefectures of Yanyun?
The present Yanyun Sixteen Prefectures are simply the present-day Beijing Municipality, most of Hebei and part of Shanxi. The ancient Yanyun Sixteen Prefectures were actually called Youyun Sixteen Prefectures or Jiyun Sixteen Prefectures, which were the places where soldiers fought since ancient times. Before the Song Dynasty, this area was the dividing area between the Central Plains Dynasty and the northern steppe peoples, and it was also a good place for the Central Plains peoples to resist the northern peoples and raise horses and herd horses.
During the qin shi huang period, he attached great importance to the sixteen prefectures of Yanyun, and in order not to expose the central plains to the eyes of the steppe peoples, the Great Wall was built there from the beginning of Qin Shi Huang.
The reason why Yanyun Sixteen Prefectures were lost was mainly due to one person, and this person was Shi Jingyao.
Shi Jingyao was the envoy of the Later Tang Dynasty at that time, and he was also a famous emperor in history. In 939, Shi Jingyao, in order to be able to defeat the Later Tang and complete his dream of becoming emperor, borrowed the power of the Khitans. Of course, there is no free lunch in the world, and the reason why Shi Jingyao let the Khitan send troops was to cede it to the fertile Yanyun Sixteen Prefectures of the Khitans, and in addition, in order to express his sincerity, Shi Jingyao even brazenly called the Liao Taizong Yelü Deguang, who was ten years younger than himself, his "father emperor".
After the establishment of the Song Dynasty after the sixteen states of Yanyun, it was always exposed to the iron hooves of the Liao state, and in the more than three hundred years of the founding of the country, it was constantly threatened by the nomadic peoples in the north, and finally it was destroyed by the powerful Mongol nation.
It was not until Zhu Yuanzhang established the Ming Dynasty that the Sixteen Prefectures of Yanyun, which had been wandering, were retaken by the Central Plains Dynasty.
In short, every inch of China's land in successive dynasties has been guarded by blood, whether it was before or now, any country that wants to seize any inch of our land, as Chinese, we are resolutely opposed, and anyone who betrays his own interests will never have a good end.
