Explanation:
One of the most important developments of the Songdynasty was the fact that Confucianism became reinvigorated with new ideas, known as Neo-Confucianism. These ideas also encouraged the development of a more organized bureaucracy. Bureaucrats were selected through imperial examinations, and this led to a scholar elite that belonged to the government. This government developed the equivalent of a modern cabinet.

This was particularly prominent during the Song dynasty, and it attempted to unite the more abstract parts of Buddhism and Daoism with the pragmatism of Confucianism.
