"The so-called knowledge in the case of things, words with my knowledge, in front of things and poor. Cover the soul of the human heart, know everything, everything in the world is unreasonable, and there is no shortage of knowledge because it is reasonable. Taking "University" as the starting point, scholars can be familiar with everything in the world and benefit from its known reasons, so as to achieve the ultimate. As for the hard work for a long time, once suddenly enlightened, everything is fine and thick, and the use of the heart is unknown. This is called the case of things, and this is called knowing. "

This passage emphasizes "knowledge" through "things" and emphasizes two points: first, cases and unqualified, and second, whether to dabble in or get to the bottom of it. At first I explained, "I am poor in things"-I want to explore the principle of things. And so on. It shows that the human mind has cognitive ability, and so on. Everything is animistic and has its internal principle. Because there are endless things to explore, people can get endless knowledge from them.

The first two sentences clarify the relationship between knowledge and rationality, and based on this theory, the usage and standards of teaching are explained below. -"Because of its well-known principle, it is beneficial to the poor." In order to achieve the ultimate. "This sentence can be understood from two aspects: on the one hand, starting from the appearance of things, going deeper and deeper, analyzing the meaning of things and exploring the essence of things; On the other hand, starting from the known principles, tracing back to the source and comprehensively restoring the origin of things. These two aspects, one emphasizes depth and the other emphasizes breadth.

As for the effect, it depends on the strength of kung fu and the length of time. "For a long time." Emphasizing the accumulation of quantity, "suddenly enlightened" means that the quantitative change reaches a certain level and qualitative change occurs. Here, I have a clear understanding of what I have, including inside and outside, framework and details. At this time, I have been enlightened and my heart is much clearer. That's it, that is, I not only understand things, but also clarify my mood, so that knowledge can really be integrated into my own blood and become a part of my body.

In university, the teacher's role has changed from imparting knowledge to researching knowledge, so what the teacher teaches in class is actually the known theory, which is the tip of the iceberg. Most of the rest is still submerged in the sea and students need to explore it themselves. For example, the teacher is known to tell us the conclusion of an experiment in class. What we need to do is to query all kinds of materials after class, understand the process, background and practical application effect of the experiment, and even understand other similar experiments to compare and analyze the scientific nature of the experiment, so as to understand the theory more deeply, or to question and supplement the experimental conclusion at a higher level.

In short, college students should get rid of the idea of "taking it for granted" in middle school and rely on their own resources to learn things.
