For the original text, see Wei Linggong in The Analects of Confucius: "Confucius said,' Is there any kind of teaching?'" This means that the goal of education is regardless of category. Yes, as an initial auxiliary word, it has no real meaning. In the Yin and Zhou Dynasties before Confucius, education was the responsibility of the government, and only the children of nobles could enter official schools. Confucius started a private school in the history of our country. As long as you provide a certain tuition fee, you can receive education. "Teaching without distinction" means that I educate anyone who asks me for advice, no matter how poor, rich, expensive, cheap, virtuous or stupid. This concept of educational equality has made great contributions to the educational development of China and human beings.
