Why is Confucius the soul of China traditional culture?

Confucius was a famous thinker, educator and founder of Confucianism in ancient China. According to legend, there are 3000 disciples and 72 disciples of saints. Confucius led his disciples around the world 14 years. In his later years, he devoted himself to sorting out ancient documents, editing poems and books, defining rites and music, and making a preface to Zhouyi for Chunqiu. His thought takes "benevolence" as the core, and "benevolence" means "loving others", and advocates the implementation of "benevolent politics", which should be based on "courtesy" and "self-denial and courtesy as benevolence"; Put forward the idea of "correcting the name" and think that "Jun Jun, minister, father and son" should be worthy of the name; Pay attention to the combination of "learning" and "thinking". The so-called "learning without thinking is useless, thinking without learning is dangerous"; Advocate the atmosphere of teaching in private schools, advocate teaching students in accordance with their aptitude, "teach without distinction", "never tire of learning, never tire of teaching", and emphasize that "a gentleman learns to love others, while a villain learns to learn easily". Since the Western Han Dynasty, Confucius' theory has become the cultural orthodoxy of feudal society for more than two thousand years, with far-reaching influence. The existing book The Analects of Confucius records the questions and answers between Confucius and his disciples, which is the main material for studying Confucius' theory.
