The administration of Qin Dynasty was mainly based on Confucianism and Legalism. At the beginning of the founding of the People's Republic of China, Qin advocated Confucianism and implemented cultural and educational policies based on Confucius' thoughts of benevolence, propriety and filial piety, so as to standardize social order, strengthen state management and improve national quality. Later, because the folk customs of Qin adopted a hundred schools of thought, Confucianism could not completely solve the current practical problems. In addition, Confucianism contains the content of opposing autocratic regime, and Qin Shihuang gradually turned to legalism, and strengthened his rule and control by implementing the policy of emphasizing the rule of law and rewarding and punishing severely. The thought of governing the country in Qin Dynasty was based on Confucianism and Legalism, which influenced and supplemented each other. Although legalism became the dominant ideology in the late Qin Dynasty, Confucianism still maintained a certain influence in the political, cultural and educational fields of the Qin Dynasty.
