The Qin Dynasty took legalism as its ruling ideology. Therefore, heavy punishment and heavy law are highly respected, while other theories, especially Confucianism, are suppressed and eliminated. But to tell the truth, Confucianism flouts the law. It's time to clean up.

On Dong Zhongshu's advice, Emperor Wu of the Han Dynasty deposed a hundred schools of thought and respected Confucianism alone. Since then, Confucianism has really stepped onto the stage of the ruling class.
