Liu Che was a very successful emperor in the Western Han Dynasty. He created a "prosperous period of Hanwu", which pushed the Han Dynasty to its peak and became another unified dynasty.

Liu Che, the Emperor of the Han Dynasty, advocated the Confucian theory of practical application. He adopted Dong Zhongshu's idea of "ousting a hundred schools of thought and respecting Confucianism alone" and advocated the Confucian theory of putting practical things into practice. Therefore, Emperor Wu of the Han Dynasty established imperial academy and adopted a series of measures to make Confucianism the ruling ideology of the dynasty.

In the early Han Dynasty, Huang Lao's theory of "governing by doing nothing" was carried out to let the people recuperate. At the beginning of the Han Dynasty, the economy recovered rapidly, and there was a prosperous time of "ruling by Wenjing". However, by the time of Emperor Wu of Han Dynasty, Huang Lao's theory of "governing by doing nothing" could not meet the needs of ruling. Emperor Wu of Han Dynasty adopted Dong Zhongshu's opinion and praised Confucianism.
