First of all, from Song Taizu, the emperor ruled the world with scholar-officials, and Song Taizu also carved his ancestral precepts, not killing scholar-officials. The Song Dynasty respected literati very much, which can be seen from the fact that both men and women in the Song Dynasty could read books. Because of the preferential treatment for literati, officials in Song Dynasty were very loyal to the imperial court, and many literati warriors loyal to serving the country appeared. Secondly, people in the Song Dynasty especially advocated honesty. Wen Tianxiang's loyalty to serve the country, Yue Fei's loyalty to serve the country, and Lu Xiufu's devotion to the sea and martyrdom reflect the integrity of the Chinese nation and their dedication and blood. People in the Song Dynasty took this as an example, and the national luck in the Song Dynasty continued.
Moreover, there were not only national laws but also family rules in the Song Dynasty, and the peace of a small family ensured the peace of the royal family in the Song Dynasty. In addition to family rules, the royal family also received higher treatment. When they reach the age of seven, they can be awarded officials and enjoy wages and subsidies according to their status. In addition, penalties and hard labor are reduced, concubines in the harem are not allowed to participate in politics, parents are not allowed to grant officials, and ministers are not allowed to enter the harem privately. Song dynasty didn't ask much about the status of a queen. Liu E, for example, can still be a queen if she is a commoner or has a second marriage. Treat eunuchs, in addition to being responsible for the daily life of the emperor, they can also be generals who lead troops to fight. Many eunuchs granted official positions, but they did not reach the scope of rule. There are clear legal provisions for officials in the court and concubines in the harem, which have been implemented to a great extent.
In Song Dynasty, justice was valued over profit, which greatly promoted economic development and guaranteed people's living standards. At that time, the economic prosperity was absolutely the highest in the world, far ahead compared with other dynasties. The only weakness is that it attaches importance to Confucianism and obeys the will of the people. Even if its neighbors openly provoke war, it is unwilling to wage war. There is also the fact that the emperor at the end of the Song Dynasty was too pedantic and far from virtue, which led to the final decline of the Song Dynasty.
