Emperor Wu of the Han Dynasty adopted Dong Zhongshu's suggestion of "ousting a hundred schools of thought and respecting Confucianism alone" in order to achieve the unity of thoughts. Influence: Confucianism as the orthodox thought of feudal rule established the orthodox position of Confucianism in feudal rule and adapted to the needs of society at that time. In the early Han Dynasty, the country was poor, and the ruling thought of Taoism was suitable for the development of society at that time and played a very good role in restoring production. However, by the time of Emperor Wu of the Han Dynasty, with the development of economy, the enfeoffment forces in various places also grew, which affected centralization and social contradictions changed. Therefore, the ruling ideology has changed accordingly. Implementing "ousting a hundred schools of thought and respecting Confucianism alone" and realizing ideological unity are conducive to the strengthening of centralization. After Confucianism was established as the orthodoxy of authoritarian dynasties, it lasted for more than two thousand years. In order to ensure the implementation of the policy of "ousting a hundred schools of thought and respecting Confucianism alone", Emperor Wu of the Han Dynasty vigorously promoted Confucian education, repeatedly issued letters to seek talents, set up imperial schools in the central government, set up official schools in local areas, and trained officials and educated the people with Confucianism. Since then, the study of Confucianism has become increasingly popular. However, the exclusive situation of Confucianism, which lacks contention, makes academic last stand, thus imprisoning people's thoughts, which is actually a kind of cultural autocracy.
