The first thing is to pay attention to personality differences. Confucius put forward for the first time in the history of China that people's natural qualities are similar, and the differences in personality are mainly influenced by acquired education and social environment ("similar in sex, far from learning"). Therefore, everyone can be educated and everyone should be educated. He advocated "no education for all", founded private schools and enrolled more students, which broke the monopoly of slave owners and nobles on school education and expanded the scope of education to civilians, conforming to the trend of social development at that time.
The second is to teach students in accordance with their aptitude. In terms of teaching methods, Confucius requires teachers to have the educational philosophy of "teaching without distinction" and "managing the country to help the world", the methodology of "teaching students in accordance with their aptitude" and "heuristic", and pay attention to early childhood education and enlightenment education. He educates students to have an honest learning attitude, be open-minded and eager to learn, review what they have learned from time to time, so as to "review the past and learn new things", broaden and deepen the extension of new knowledge, and "draw inferences from others".
The third is profound knowledge. His knowledge is completely accumulated and he is very eager to learn. He is also very confident in this: "In a city with ten rooms, there must be people who are as loyal as Qiu, but not as eager to learn as Qiu" (The Analects of Confucius, Gongye Chang). As a result of his eagerness to learn, he is not only proficient in the six arts, but also knowledgeable, and many rare problems can be solved when he gets his hands on them.
Fourthly, Confucius is the collator and master of ancient documents. According to his knowledge, Confucius divided it into six arts to teach people. However, at that time, Zhou declined, "rites and music were abolished, and poetry and books were lacking." So Confucius followed the ceremony of three generations, making fun with pens, deleting poems, prefacing books, performing the Book of Changes and cutting Spring and Autumn Annals. Thus, China's cultural purpose was established.
Finally, Confucius' attitude towards life and moral cultivation became an example for China people. His love for culture, commitment to Tao, concern for people, persistence in ideals, emphasis on self-cultivation and requirements for personality are all very positive. In particular, he was born in troubled times, giving up all rites and music. He rebuilt Zhou Wen's positive attitude, knowing that he could not do it, which highlighted the Confucian character of not being afraid of difficulties and was regarded as a saint by later generations.
