What do you mean by "big knock means crow, small knock means crow"?

The meaning of "big knocking means ringing, and small knocking means ringing";

Knocking hard will make a loud sound, and tapping lightly will make a small sound.

The Book of Rites says: Be kind to the questioner, such as ringing a bell; Knocking small will make a big noise; If you knock loudly, it will ring loudly; Wait for them calmly and then go all out; People who are not good at answering questions will do the opposite.

This means that a teacher who is good at answering questions is like ringing a bell. If he knocks gently, the bell will be smaller. A heavy knock on the door will ring. When the bell rings, let its sound end. People who are not good at answering questions are the opposite. This is China's earliest book on the art of answering questions. It uses the metaphor of "ringing the bell", which is not only boring, but also vivid and meaningful. Three of them are worth pondering and learning from. You must be able to hear the bell, and you must understand when others ask you. Bells are a science.

Many people smashed into pieces, on and off. The first reason is that they can't hear the sound, and naturally they can't grasp the strength and orientation in their hands, so the bell can't be round, loud and vigorous. The process of waiting for questions is actually a process of listening. Teachers should grasp the correct questions and understand the meaning of the questions through listening. To achieve the realm of "goodness", teachers must practice "listening skills" to be able to hear, hear clearly and understand.

Talking and thinking are in line with the law. Recruit some talented people to help you. It is enough to have a small reputation, but it is not enough to be a general in command of the army. A man of noble virtue and close to versatile talents is enough to be a general in command of the army, but not enough to educate his subjects and become a beauty. People on the throne must learn if they want to educate their subjects and become beautiful customs!

Jade is not a tool; People can't understand Confucianism without studying. Therefore, the three kings in ancient times should take education as their primary task when building the country and ruling the people. In the chapter of Shangshu, it is said, "We should always try to learn the classics of my late king from beginning to end".

Even if there is something delicious, you don't know its delicacy if you don't eat it; Even if there is an excellent truth, you won't know the secret unless you learn it. So I didn't know my ignorance until I studied deeply, and I didn't know my ignorance until I taught and educated people. Only when you know that you are lacking in virtue can you reflect on yourself, and only when you know that you are ignorant can you encourage yourself. Therefore, teaching and learning complement each other. In the chapter of "Shangshu Duiming Names", it is said that half of the role of educating others is to increase one's knowledge of virtue. That's what it means.

In ancient times, schools were set up to educate students. Every school is called Shu, and every political party is set up to educate students. Every school is called "Xu", and there are universities in the country where the emperor or prince lives. Freshmen can enter school every year and take exams every other year. In the first year, students' ability to separate the meaning of scripture and to identify their own wishes was investigated. In the third year, we will examine whether students respect their teachers and can live in harmony with their classmates. In the fifth year, we will check whether students study extensively and respect teachers. In the seventh year, students' academic opinions and friends' choices are investigated, which is called "Cheng Xiao".

The ninth year, called "Dacheng", examines whether students can draw inferences from others, be knowledgeable, not be confused by the situation, and not violate the teacher's teaching. Then educate the subjects, change the customs, make the close people convinced, and the alienated people will join in. This is the outline of university education. "Historical Records" says: "Young ants always learn from it (young ants always learn from the soil and become great things, just as scholars always learn from it and become a road)." That's what it means.
