Influenced by the prosperity of Buddhism and Taoism, Confucianism gradually lost its dominant position since Wei, Jin, Southern and Northern Dynasties. Han Yu himself advocates retro and opposes Buddhism. Strive for the dominant position of Confucianism instead of Buddhism or Taoism. It played a pioneering role in the later Neo-Confucianism in Song and Ming Dynasties.
Han Yu called Mencius the heir of Confucius in The Inheritance of Taoism, and thought that the loss of the sage's way after Mencius made Mencius have the same status as Confucius in Taoism, which greatly improved Mencius' position. Scholars who influenced Neo-Confucianism in Song and Ming Dynasties later included Mencius in the Four Books, which really improved Mencius' position in China culture.
In addition, Daxue was honored as one of the four books in the Song Dynasty and gained the status of an important Confucian classic. In fact, the discussion of universities has already begun in Han Yu.
