Dong Zhongshu developed the part of Taoism, Yin-Yang school and Confucianism that is beneficial to the rule of monarchs and kings, and developed the new Confucianism as the basic theory of exclusive respect for Confucianism.
During the popularization of Confucianism in Han Dynasty, many social problems were solved. Confucianism tends to manage the country with benevolent policies, and politicians use this as a basis to limit the excessive concentration of land and establish a sound moral system.
Extended data:
Confucianism suffered a heavy blow after the unification of Qin dynasty, and Confucianism became the object of attack. Fortunately, the rule of the Qin dynasty did not last long, and the Han dynasty soon took its place.
By the time of Emperor Wu of the Han Dynasty, with the efforts of Dong Zhongshu, Confucianism really defeated Taoism and Legalism, and gained a dominant position in the ideological field for more than two thousand years.
It was Dong Zhongshu who made an all-round and multi-field adjustment to traditional Confucianism, so that Confucianism, which had been hit hard and neglected, could keep up with the development of the times and meet the needs of the ruling class, and eventually became a feudal orthodox thought, which spread in China for two thousand years.
However, Dong Zhongshu's transformation of Confucianism catered to the needs of rulers too much, and introduced many backward theological concepts into Confucianism, which laid a curse for the decline of Confucianism.
