Ye Shi, a famous political commentator in the Song Dynasty, pointed out that there was only one reason for the "blood loss" of the Han nationality: the monarchy was too concentrated. In his book On the Beginning, he said: "Power belongs to the upper class, soldiers are soldiers, the source of wealth, and a place is guarded by everyone." "The only thing you can do is to work hard, but you can become rich and relaxed with hard work."
Ye Shi believes that power is highly concentrated in the central government, which is conducive to internal governance, but it is defeated by external defense. Under the strict control of the imperial court, the whole country is forbidden to talk about military affairs. The national army only obeyed the monarch, and the people were unarmed, so they had to "sit back and watch Land Rover go deep"
Ye Shi further pointed out that to change this situation, the central government must implement decentralization and give local autonomy. In this way, they can each take responsibility for the country. "The people are also people, and this is also the case."
It can be said that as an authority, Ye Shi is not fascinated, and his words are basically to the point. If any nation wants to build a strong country, it should be "soft inside and firm outside"-those who are solid outside should be strong, and those who are comfortable inside should be soft. However, the rulers of China often do the opposite, which leads to frequent foreign invasion and national humiliation. It is also the reason why the Han nationality is strong in Tang Dynasty and weak in Song Dynasty that the "dual system" in Tang Dynasty is loose at home and tough at abroad. The Song Dynasty was "tight inside and loose outside". How is it possible that the whole country is talking about the discoloration of arms?
Although Ye Shi made suggestions to Emperor Zhao and Song, it didn't help in the end. Because Emperor Zhao and Song played a small abacus, insisted on "keeping the inside and not keeping the outside" and exchanged money and land for peace in order to seek political security.
And Gu 'an's regime will not last long. At the expense of giving up the North, the Song Dynasty lingered on 152, destroying the Jurchen State of the Jin State, but a more powerful foreign enemy, the Mongolian Empire, rose. This foreign enemy is more powerful and greedy than ever before. They not only want the Central Plains, but also insist on taking the whole China south. Under the iron riding of the Mongolian Empire, the safe and conservative Southern Song Dynasty was finally annexed.
