Where does 举一反三 come from?
In the 《论语》, Confucius describes how he taught: he wouldn't open the way for a student until the student had struggled to understand and couldn't find the words. And he added that if he held up one corner and the student couldn't come back with the other three, he wouldn't repeat the lesson. The image is a square object: anyone who has truly understood one corner can work out the others alone. That's where the idiom comes from, said today of someone who learns one case and carries it over to many others. In school and at work it's said above all in praise of someone who catches on fast and doesn't need to be told twice.
