Because during the period of Emperor Wu of the Han Dynasty, Emperor Wu of the Han Dynasty and his Dou Fei family fought for power and profit. Dou's family believed in Huang Lao's theory. In order to consolidate centralization, Emperor Wu of the Han Dynasty decided to respect Confucianism. One of the famous representatives is Dong Zhongshu, who sorted out the Confucianism of Confucius and Mencius, and launched "Confucianism" with the slogan of "ousting a hundred schools of thought and respecting Confucianism alone". Dong Zhongshu's neo-Confucianism put forward a series of ideas to meet the needs of the times. Emperor Wu of the Han Dynasty vigorously promoted the development of Confucianism, fully affirmed Neo-Confucianism, used hundreds of Confucian scholars to participate in state affairs, and established the imperial academy, so that all scholars in the world studied Confucian classics, because Confucianism adapted to the needs of rulers, and its ethical theory could stabilize the people's hearts, thus contributing to the ruler's rule, which was also closely related to the prosperity of national strength and the stability of people's lives during the period of Emperor Wu of the Han Dynasty.
