Being eager to learn and make progress is not a poem in ancient poetry, but a sentence in The Analects of Confucius. The whole sentence is sensitive and studious, and I am not ashamed to ask questions. A person's real knowledge lies in knowing what he knows and what he doesn't know. Know silently, never tire of learning, never tire of teaching.
The complete definition is: a smart and studious person is not ashamed to ask for advice from people with lower status and less knowledge than himself. Knowing is knowing, and not knowing is not knowing. This is true wisdom. Remember what you have learned silently, so that you are not satisfied with your study and don't know how tired you are.
