Compared with On Qin and On Six Kingdoms, A Fang Gong Fu has the same feature: it takes the rise and fall of Qin and Six Kingdoms as the topic, and urges the dynasty to take a warning in view of the promising political situation at that time. The originality of each argument lies in:

Regarding the death of Qin, Jia Yi revealed for the first time in history that the root cause of Qin's death was "benevolence and righteousness are not applied, and the offensive and defensive trends are different". Of course, we must seize the world by violence. However, if we use violence against violence and take the people as the enemy, we will be in a "lonely" position in the sea of Wang Yang, and our demise is just around the corner. This argument is very refined and profound, and the rise and fall of later dynasties have proved Jia Yi's profound knowledge and foresight.

(2) The uniqueness of Su Xun's The Six Kingdoms lies in that, unlike many previous writers who always discussed it from the perspective of lashing Qiang Qin's atrocities, for the first time, he discussed it from the perspective of the internal causes of the collapse of the six countries, and his analysis of the internal causes was all-round, involving politics, economy, diplomacy, military and other aspects, showing his unique views everywhere.

(3) Although Epanggong Fu is a "Fu", it accounts for half of the discussion. It can be said that the paper is written in the form of fu, which is original in itself; Secondly, its originality lies in that the author chose a concrete and vivid thing as the angle of argument, and regarded Epang Palace as a symbol of the arrogance and extravagance of the Qin Dynasty, as a witness of the oppression of the people by the Qin Dynasty, and as a symbol of the collapse of the Qin Dynasty. This way of argument is even more unique.
