What are the basic characteristics of Confucianism?

Confucianism basically adheres to the legislative principles of "pro" and "respect", maintains "rule by courtesy", advocates "rule by virtue" and attaches importance to "rule by man". Confucianism has a great influence on feudal society and has long been regarded as orthodox by feudal rulers. Confucianism, also known as Confucianism or Confucianism, was founded by Confucius, initially referring to the state of etiquette, and then gradually developed into an ideological system centered on the order of benevolence, which was the most influential school in China and the mainstream consciousness in ancient China. During the period of Emperor Wu of the Western Han Dynasty, Dong Zhongshu absorbed the factors that were beneficial to absolute monarchy, such as Taoism and Legalism, reformed Confucianism, and added the idea of "divine right of monarch" and unified unification, which was objectively beneficial to the strengthening of feudal centralization, social stability and the consolidation of Confucianism. Since then, Confucianism has gradually become the dominant orthodoxy in feudal society. Throughout the past two thousand years, Confucianism has been able to dominate, on the one hand, because its ideological core, that is, the philosophical concept of harmony between man and nature, the ethical concept of "three cardinal guides and five permanents" with "benevolence" as the core, and the political proposition of unified unification, have fundamentally adapted to the needs of feudal autocratic rule.
