Wei Linggong, the original sentence is "Confucius said:" There is no class in teaching. "No matter who can be educated, some people are not excluded from education because of the rich, the poor, the humble, the foolish, the good and the evil. This kind of educational thought was advocated by Confucius, who clearly put forward the idea of "teaching without distinction" on the issue of educational objects. " "Teach no class" means that foreigners, regardless of nobility, civilians, national boundaries and China people, can enter school and be taught as long as they are willing to study. Option d "It's a pleasure to have friends from afar" comes from the Analects of Confucius? Learning, isn't it a pleasure to have friends coming from afar?
