First, in the Spring and Autumn Period, Wang Guan failed to learn, and Confucius pioneered the art of private lectures, set up an apricot altar to teach his disciples, sorted out and took poetry, calligraphy, ceremony, Yi, Yue and the Six Classics of Spring and Autumn as teaching materials, and took the six arts of ceremony, music, shooting, imperial, calligraphy and mathematics as educational contents;

The second is to break the rich-poor level of education and outline "education without class" so that everyone can enjoy equal educational rights. There are many students, and the history books say that "two people are proficient in six arts";

Third, we advocate respecting teachers, saying that "if there are three people, there must be my teacher" and "if you are a teacher for one day, you will be a father for life".

His tireless teaching spirit, the teaching principle of teaching students in accordance with their aptitude, paying equal attention to learning and thinking, and his learning attitude of "not ashamed to ask questions" have been praised and used so far. Confucius was the first professional teacher in the history of China and the greatest educator in ancient China, so he was called "the most holy teacher" and "the model of later generations".
