The allusion of this sentence comes from the Book of Rites, which is a metaphor for people who are good at answering questions with the power of the clock. The original text is as follows:
Good scholars can learn from others and get twice the result with half the effort, so they are mediocre. Poor scholars and diligent teachers get twice the result with half the effort, so they complain a lot. People who are good at asking questions are like attacking wood. Those who are easy first, then their procedures, after a long time, tell each other to solve. People who are not good at asking questions are the opposite. Be kind to those who ask questions, such as ringing the bell. If you tap them gently, they will ring. If you hit them hard, they will ring. Wait for them calmly and then go all out. People who are not good at answering questions are the opposite. This is the way to learn.
Vernacular translation
Those who study well are relaxed, but the teaching effect is twice as good. Students learn from their teachers and attribute the credit to their good teaching. Those who don't study well, the teachers are diligent and the students have little effect. Students follow the teacher and complain that the teacher is not teaching well. People who are good at asking questions are like carpenters cutting hardwood, starting with the smoother parts and then cutting hard knots. At that time, students will understand it easily. People who are not good at asking questions are just the opposite.
A person who is good at answering questions is like ringing a bell. Jason Chung is weak, but the clock is strong. He made the loudest sound when he hit as hard as he could. People who are not good at answering questions are just the opposite. These are all ways to improve learning.
