"No one can be left behind" comes from The Analects of Wei Linggong. Its main meaning is to express that everyone should be educated, and there should be no classification, let alone class and rich and poor.

Confucius was the first person to put forward heuristic teaching, and he also made great achievements in educational thought. Many educational methods are still in use today, such as "learning from the country to help the world", "teaching students in accordance with their aptitude", "reviewing the past to learn the new" and "drawing inferences from one example to another". In addition, Confucius also attached great importance to children's education and enlightenment education.

Confucius' educational thoughts mainly include:

1, knowing means knowing, and not knowing means not knowing: this is the basic quality of seeking truth from facts;

2. Teaching students in accordance with their aptitude: different educational methods are adopted according to different personalities to enhance the teaching effect;

3, a threesome, there must be my teacher: only by humbly asking others, can we constantly improve ourselves;

4. Be diligent in thinking: be diligent in learning and asking questions to acquire knowledge;

5, review the old and learn the new: always review the knowledge you have learned before, in order to learn new knowledge well;

6. Don't be ashamed to ask questions: encourage everyone to learn with an open mind and ask for advice with an open mind.

Confucius (55 BC1September 28th-BC 1 1 April)? Zi, surnamed Kong, was born in Lu (now Qufu, Shandong) at the end of the Spring and Autumn Period. His ancestral home was Song (now Xiayi, Henan). He was an ancient thinker, educator and founder of Confucianism in China. He initiated the atmosphere of private lectures and advocated benevolence, righteousness, courtesy, wisdom and faith.

Confucius constructed a complete ideological system of "virtue and virtue": he advocated the virtue and virtue of "benevolence and courtesy" at the individual level. The ideological system of virtue and Taoism is based on the theory of goodness of human nature ("one yin and one yang refers to the Tao, and those who follow it are also good, and those who succeed are also people"), aiming at establishing the human pole ("three-pole Tao"), and connecting with human nature, heaven and tunnel, and the golden mean will become a complete methodological ideological system in due course.

The most important economic thoughts of Confucius are "emphasizing righteousness over profit" and "enriching the people". This is also the main content of Confucian economic thought, which has a great influence on later generations.

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").
