Explanation:

This question refers to the text "Legalism, an Ancient Chinese Philosophy," by Bridgette Byrd O'Connor. According to the text, Li Si lived in the Qin state during a time in ancient China where rulers were trying to restore order and bring back glory to the Chinese people. Li Si was an adapt of legalism; he created rules and reorganized the state in order to create structure. However, the adepts of Confucianism were not happy about some of the measure Li Si took. One of the reasons why they disapproved of him was his banning history education and calling for book burning. Confucians also believed in order and structure, but not through such rigid ways.
