It means that people with moral cultivation are smart and eager to learn, and they are not ashamed to ask people lower than themselves. Learning is not boring, and educating others is not tiring.

Source: The Analects of Confucius, Gongye Chang, 15th. This section is about Confucius' evaluation of people at that time and around that time. This character's comments include how to learn and the overall cultural spirit.

This chapter of The Analects emphasizes two points:

1. Generally speaking, smart people are not very studious. Because they are smart, they will take their cleverness as their natural advantage, so naturally they will not study hard, and it is even harder to persevere in a certain field.

If you are talented and eager to learn, you will learn quickly and eager to learn. It is difficult for such people to think of great things.

Generally speaking, people in high positions are ashamed to ask questions. Only those who are simple-minded, respect the facts and have a thirst for knowledge will ask questions, because in their view, all this is natural, natural and simple.

Today, being eager to learn and not ashamed to ask questions has become an idiom. I believe this spirit of scholarship can be passed down in the Chinese nation.
