In the last years of the Northern Song Dynasty, there were no guards, and the Jin soldiers surrounde

Ask a historian this question.

This is just a trap of the Northern Song Dynasty, in fact, the Northern Song Dynasty did not have 800,000 troops, just to attract the 150,000 troops of the Jin State, and then break through it in one fell swoop.

This is because the military strength of the Northern Song Dynasty was relatively weak, and it was related to the emperor's rule, because the emperor was mediocre and incompetent, so this situation occurred.

I think this is because the purpose of the Jin Kingdom is to plunder gold, silver, jewelry, beautiful women, etc., so it did not unify the Central Plains.

The main reason was that the Jin State also had to face many opponents at that time, and the Jin State simply did not have the energy to unify the Central Plains.

In the end, the reason why China was not unified was because of the policy at that time and the fact that they only attacked and did not protect the rear, which led to the fall of the back, so that they did not unify the Central Plains, and they were not Central Plains people.

Because there are many other small countries in the Central Plains, and the geographical location of the Central Plains is relatively complex, the Central Plains region is not unified.

This is because this battle is very difficult to overcome, and the terrain is relatively complex, and the strength of the enemy army is also relatively strong, so it is very difficult to unify the Central Plains.

Because they have been fighting wars and have not developed their own internal affairs well, they have led to a shortage of food and the people are living in great misery.

Because it is not so easy to unify the Central Plains. At this time, their internal consumption is very large. There is not enough capacity to agree.

After the fall of the Northern Song Dynasty, the Northern Song Dynasty royal family crossed the Yangtze River and established the Southern Song Dynasty regime, because of the Yangtze River natural danger, it was difficult for the Jin State to defeat the Southern Song Dynasty, and in the later period of the Jin Dynasty, the Mongol military power appeared in the north. The Jin State had no time to unify the Central Plains.

At that time, there were still Mongolia and Liao in the north, and the Jin State had to deal with these two countries in addition to the Northern Song Dynasty, so its energy was still limited, and at the same time, its strength was not very strong.

A: Because the Jin State also faced the threat of the Mongol army, there were not many troops to unify the Central Plains.

It was because its own strength was not very strong at that time, and if you wanted to achieve reunification, you would need to put in a lot of effort in the process, and you often didn't need to make some decisions in uncertain situations.

Because their ability at that time was not enough to unify the Central Plains, and the rulers only cared about pleasure.

The reason is simple. Although the Northern Song Dynasty had perished, its vitality and strength still existed, and the Southern Song army also frequently attacked northward, stabilizing the front line of the Huai River, Qinling and Dasangguan. The two sides are basically equal.

In an all-out struggle with the Song Dynasty, the Jin State left the pasture nomadic tribes of the north. The rise of the machine threatened the territory of the Jin State, and the Western Xia regained its vitality, and the Jin State did not have the strength to defeat the Southern Song Dynasty, so it could only maintain the status quo.

That's because there were many countries at that time, and it was also because the strength of the other side was very strong.

Because the armed forces of the Central Plains were particularly strong at that time, the Jin State was not the opponent of the Central Plains at all, and the water and soil were not adapted, so there was no unification.

It was because his military capabilities were not particularly strong at that time, and he did not have particularly good experience in this area, so he did not unify the Central Plains.

Because his strength is not strong, his strength is not so strong, and he cannot defeat everyone, so he did not unify the Central Plains.

The first time the Song Dynasty took the initiative to attack Jin, called (), but the Song Dynasty quickly defeated the end of the burning shed.
