温故知新

- To review what one has already learned and gain fresh understanding from it; revisiting the old reveals something new.
Where does 温故知新 come from?
The phrase comes from the Analects of Confucius, in the chapter "Weizheng" (On Governance). There Confucius says: "One who can gain new understanding by reviewing the old is fit to be a teacher of others" (温故而知新,可以为师矣). It is not a narrative tale but a maxim by Confucius himself on learning: merely memorizing what is already known is not enough; true knowledge means returning to what one has learned and drawing fresh insight from it. For this reason it became one of the most frequently cited teaching principles of the Confucian tradition.
