First, understand the general idea. When you remember something, you must first understand its general content. Take reading as an example, you should read through it or browse it first. If it is memorizing music, you should listen to the whole song first. Only by understanding the whole picture can we have a deep understanding of the local. This is also "synthesis".
Second, after the local analysis has a general understanding of things, it is necessary to gradually analyze them in depth. For example, for a paper, it is necessary to find out its argument, divide it into several paragraphs according to the structure, find out the main meaning one by one, that is, find out the "information point" and make careful analysis and thinking, so as to reach the level of compiling an article outline.
Third, the key to finding is what Han Yu said in Xue Ji. Find the main points, key points and difficulties of the article, explain them clearly and remember them firmly. Only on this basis can we understand and remember its less important or subordinate contents. Is "a majestic mountain, there must be a main peak;" The dragon has nine chapters, but he won one. " Fourth, mastery is to understand and remember all kinds of local contents, think repeatedly and understand comprehensively. This is more conducive to deepening memory. Whether you really understand what you have learned in practice depends on whether you can use it in practice. If you get stuck in the actual work, it means you don't really understand. There are specific standards for real understanding. One is to be able to explain it in words and phrases, and the other is to be practical. In the process of practical application, we will continue to deepen our understanding. When we understand what we have learned, we should make full use of these analytical and comprehensive methods to promote understanding and improve the efficiency of memory.
