What is the influence, reason and performance of China's policy of valuing literature over martial arts in the Northern Song Dynasty?

It is the basic national policy of the Song Dynasty to emphasize literature and suppress martial arts, that is, to "emphasize culture and education and despise military affairs" (Volume 18 of the Long Edition of Continuing to Administer Resources and Administer as a Mirror). Reason: In 960 AD, Zhao Kuangyin, the general at the end of the Zhou Dynasty, staged a mutiny in Chen Qiaoyi near Kaifeng. Wearing a yellow robe, he easily seized power from orphans and widows in the post-Zhou Shizong era and began the rule of the Song Dynasty. However, Zhao Kuangyin was not the initiator of this way of seizing power. Long before Zhao Kuangyin, Guo Wei (that is, Emperor Taizong of the Later Zhou Dynasty) and Li Shimin (who personally killed his younger brother at Xuanwu Gate) used this mode to ascend to the throne. In order to prevent such incidents from happening again, the rulers in the early Song Dynasty formulated the following important systems and implemented them as basic national policies. These basic national policies were also pursued by the emperors after the Song Dynasty, and their influence ran through the whole Song Dynasty.

Impact: At the beginning of the founding of the People's Republic of China, due to the existence of old generals, the negative effect of the policy of valuing literature over martial arts was not obvious. We can still defeat the weak southern countries militarily, including the Northern Han Dynasty. However, in the war against Liao in the early Song Dynasty, clues were revealed. Before the war, Song Taizong gave the generals a plan, but he didn't trust them. The so-called "secret law of light power" made them "unable to participate in World War I". Restricting and containing them eventually led to the failure of the campaigns of Gaolianghe and Shuangqigou. It is really strange that celebrities come forth in large numbers under such a regime and such an atmosphere. In the Song Dynasty, there were really few famous soldiers. Like Yang Ye in the early years of the Northern Song Dynasty, he was forced to die; Although Cao Bin was known as the first famous soldier in the early Song Dynasty, he could only obey orders. His son, Cao Wei, was ostracized by Ding Wei in the Song Dynasty and had to die in obscurity. Although Di Qing has outstanding achievements and is a Council member, he can only be transferred in the end because he is a military commander. Nothing is more unjust than the death of Yue Fei, a famous anti-gold star in the Southern Song Dynasty, and why the word "unwarranted" prevailed in the world.

Performance: the first step is to deprive the central and local officers of military power through a glass of wine; The second step is to send civil servants to local posts and deprive us of the administrative power of our times; The third step is to appoint someone to be a transshipment ambassador and deprive our time of financial power. In this way, the problem of arbitrary military personnel and separatist regime in the buffer region since the end of the Tang Dynasty was initially solved. Moreover, various restrictions on military commanders, such as the most prominent "more defensive method", have been described as its negative effect "only change for the better, the terrain of Shan Ye is unknown, the officers and men are unknown, the officials and the people are unfamiliar, and they have retired" (Zhang). As a result, soldiers don't know what to do, and the result of overcorrection is to develop into a ridiculous "military phobia" in the future.
