Les hommes d'Etat et les penseurs de la dynastie Qin en Chine

What advice would a scholar of Confucian thoughts who lived during the qin period give to the First Emperor? How would the scholar respond to the arguments of the Legalists? Fundamentally, from the perspectives of qin-dynasty statesmen and thinkers, what issues were at stake?

In 221 B.C., the qin succeeded at putting an end to the period of chaos in "China" conquering all the polities under the control of different regional leaders. However, while the new ruling family had to maintain itself in power, it had also to face new challenges: the Empire should be unified and the state reorganized in order to establish peace and harmony.

The "authoritarian" methods of the qin government mostly influenced by Legalists' ideas could then be largely criticized by a scholar of Confucian thoughts who would probably provide the First Emperor with different advices to solve the issues which were at stake. In effect, Xunzi described for instance the qin's method of governing saying that "they employ them [the people] harshly, terrorize them with authority, embitter them with hardship, coax them with rewards, and cow them with punishments" .
Using this Xunzi's quotation, I will attempt to imagine what advices this scholar would give to the First Emperor concerning his manner of governing in order to reestablish order within the empire and ensure its prosperity as well as its resilience.
