The hexagram of Meng (蒙) also states: 'It is not I who seek the young and ignorant, but the young and ignorant who seek me. At the first divination, I inform them. If they ask a second or third time, it is profanation, and I do not inform them.' It is not the teacher who begs the student to study hard, but the student who comes to the teacher. Only when the student asks does the teacher provide answers. Otherwise, if the teacher keeps teaching, the student will become increasingly annoyed and develop a growing aversion to learning. 'It is not I who seek the young and ignorant, but the young and ignorant who seek me'—this is the fundamental principle of education. Therefore, Confucius did not reject anyone; he taught universally, without discrimination. However, he would only teach those who 'presented themselves with a bundle of dried meat.' In fact, Confucius did not care about the dried meat itself, which is equivalent to today's tuition fees. Rather, he believed that if a student was unwilling to offer even a small tuition fee, they lacked sincerity in learning. 'At the first divination, I inform them. If they ask a second or third time, it is profanation, and I do not inform them' means that when a student asks a question for the first time, the teacher should assess the student's situation and provide an appropriate answer. If the student repeatedly asks the same question, it indicates a lack of reverence and is a form of profanity. In such cases, the teacher should not answer. We all admire Yan Hui, considering him Confucius's most appreciated student. In fact, Yan Hui's father was also a student of Confucius. When Yan Hui studied under Confucius, he was very young and intelligent. He found it strange: What could my father learn from such a teacher? I already understand almost everything the teacher says. So, he began asking questions. At first, Confucius was very patient and gave him answers. But one day, Confucius became furious: 'What are you here for? To learn or to test me?' Yan Hui did not expect Confucius to get so angry. He went home and did not dare to go out for a whole week, reflecting on himself and losing weight. From then on, he rarely asked questions. Do not think that Yan Hui's questions decreased; in fact, his questions increased. However, he would first think for himself, then consult materials if he couldn't figure it out, and only when he had no other recourse would he seek Confucius's advice. Confucius was also happy to tell him. This is what makes a good student. Learning must be proactive: proactively discovering one's own problems, proactively finding suitable teachers, and proactively asking appropriate questions. Regardless of whether one understands or not, one should pause temporarily, think carefully, ask others first if unsure, and only as a last resort ask the teacher. This is the reasonable process.
