Learn and practice from time to time

Confucius’ famous sayings. The words come from "The Analects of Confucius·Xue Er": "Confucius said: 'Learn and practice it from time to time, isn't it also said to be (pleasant)?'" Wang Su noted: "Recite and practice it from time to time, learning will not waste your work, so it is joyful." Wang Shi's "learning" and "xi" have the same meaning, which seems to refer specifically to recitation. However, Confucius taught people to learn the "six arts", including etiquette, music, archery, charioteering, calligraphy, and mathematics. "Recitation" is only "one end" (see Liu Baonan's "The Analects of Justice"). Huang Kanshu "Shi Xi" said: "Every study has three seasons." One refers to the year, the second refers to the season, and the third refers to the morning and evening. The contemporary Jiang Boqian believed that "learning is to know the new, and learning is to review the past" ("Introduction to the Thirteen Classics").

When solved in the past. This sentence can be combined with the chapter "Reviewing the past and learning the new". Yang Shuda, a recent scholar, commented: "Those who review the past but cannot learn the new are learning without thinking; those who do not review the past but want to learn the new are thinking without learning." ("The Analects of Confucius") Confucius first advocated paying equal attention to learning and thinking, and he regarded Confucius as It has a profound influence on my disciples. For example, Zixia talks about learning and thinking carefully and "The Doctrine of the Mean" talks about learning and thinking carefully, both of which believe that learning and thinking cannot be neglected.
