Sun Fu has made extraordinary achievements in his life, and his scholarship highlights the Confucian way. He believes that "writing is the way to use" and enlightenment is the most effective means to improve people's civilized quality.

Sun Fu's research highlights Confucianism. This Tao is not the so-called mysterious universe ontology of Taoism, but the highest principle of all social, political and ethical principles. He inherited the theory of Han Dynasty and established a set of orthodox theories from ancient Fuxi and Yanhuang to Yao Shunyu, and then to Duke Zhou and Confucius and Mencius. He believes that Confucius made "the rule of the world, the way of governing the country, and the preparation for rejuvenating the country."

This theory puts the elite political and moral theory advocated by Confucius and Mencius above the imperial power, making the way of spreading Confucianism the fundamental principle followed by all people, including the emperor. Confucianism became the emperor's teacher, which greatly improved the social status of Confucian scholars and constituted a strong constraint on the autocratic imperial power.

This is the most valuable and progressive highlight at the beginning of the rise of Neo-Confucianism. Although this kind of moral preaching can't fundamentally change the monopoly of imperial power, it has an objective value evaluation system in theory, which can hinder the emperor's improper behavior to a certain extent and help the people live and work in peace and contentment.

On the relationship between Tao and Wen, Tang Hanyu advocated "Wen carries Tao" and Liu Zongyuan advocated "Wen carries Tao". Sun Fu further said that "writing is the use of Tao": "Writing is also the use of Tao; Tao is the foundation of teaching. " All the articles of poetry and songs "have many purposes, but they all belong to Tao and are called articles." This criticizes the bias of Taoism in abandoning literature and respecting Taoism, and admits that the great use of literature serves the advocacy of Taoism. In his view, the so-called Confucian Six Classics are all the works of saints, and they all clarify Confucianism and Taoism. The Six Classics has a very high status because of the spread of Confucius.

Therefore, Ming Dow can't live without the Six Classics, but at the same time, he should point to the Six Classics and be reasonable. Sun Fu attached importance to the thought of the Six Classics Theory, which opened a precedent for the later Song studies, that is, Neo-Confucianism, and dared to break through the old theories of predecessors, thus carrying forward the innovative ideas and concepts in Song studies, which was also an ideological emancipation movement worthy of recognition at that time.

Sun Fu has been engaged in education for decades and achieved fruitful results. Because he believes that education is the most effective means to improve people's civilized quality, if Confucianism wants to be carried forward, it must first be educated: "Confucianism, which lasts for a long time, is also the foundation of education." Without enlightenment, people will be confused with animals, and the world will not be people's world. He criticized that it was useless for Xuan Di to despise Confucian scholars, which led to the confusion of discipline and customs, which led to the decline of the Western Han Dynasty.

Sun Fu further proposed that education should be based on imperial academy: "Scholars are the root of education and the source of courtesy. The reason why the king is prosperous, the reason why human relations are right, and the reason why Liang Jun is good. " Obviously, this links imperial academy's enlightenment with the political clarity, and puts it in the fundamental position of governing the country and calming the world. This view is very wise.

Therefore, as an outstanding educator, Sun Fu has made outstanding personal achievements all his life.
