Origin of idioms

? Su Shi's question of having a broad vision and accumulating more and contributing more comes from Su Shi's famous saying about reading and writing. If you have good knowledge, you can get it in a proper way, but if you accumulate it in a proper way, you can get it in a proper way. ? In my understanding, here? Accept an appointment? , not only refers to take little, mainly refers to take it carefully, take it carefully, take its essence and discard its dross. So-called? Take? It is the recognition and acceptance of what this book says, what it says and what it expresses. ? Take? Not expensive, but expensive, should be based on? How good is less than more? . Looking at the reading experience at home and abroad, if extensive reading is very important, then careful reading is more important. Some books, even excellent books, are often not full of words and truth, but full of loopholes, refined and rough. Therefore, we have to consider the whole situation without analysis. We must seriously think about it, distinguish between good and bad, get rid of the rough and the fine, and get rid of the false and keep the true. The more you read, the more careful you must be. Otherwise, take it blindly without analysis, and then what? A letter is better than no book? Light is useless, but heavy is harmful. It won't cost much to know your nature. The truly learned people are not those who remember a lot of dead knowledge, but those who have accumulated the essence of knowledge. People of insight in ancient and modern academic circles attach great importance to their studies? Broad vision, appointment? . See it has a choice, take it has a choice, aim at it, just take it. In the Tang Dynasty, Han Yu criticized some people for reading and writing in the same way. Selective but imprecise, vague? . Wang Anshi advocated: Is reading important? Think about it. Take it carefully, okay? .

Yuan Mei, a good reader in Qing Dynasty, explained Du Fu's poems in Poems with the Garden? Reading is like breaking thousands of volumes, and writing is like a god? Say: Cover up its body, take its spirit, and don't use its dross? Reading is like eating, people who eat well will grow up, and people who don't eat well will have phlegm tumors. ? Einstein had an incisive remark when talking about reading: find out what can lead you to the depths in the books you read, and throw away everything else, that is, throw away everything that goes beyond your mind and tempts you to deviate from the main point. ? Undoubtedly, this is an insightful article based on personal experience, which is thought-provoking and worth learning. To be knowledgeable and refined, we must first be able to understand the essence. Read the book carefully, ponder it over and over again, and know its essence. Zhu's in the Song Dynasty? Skinning, fleshing, pulping? The method is quite insightful. He said: the essence of books? It's like looking for a package several times, huh? Need to be peeled again? Peel off its skin and see its meat; Remove its meat and look at its bones; Remove its bones and see its bone marrow. ? Understand? Skin, meat, bones, bone marrow? Where it is, we can know fairly well and take its essence. Otherwise, it will rarely be taken blindly. Here, the author reminds me of four metaphors of English writer Coleridge about reading. He said: Some people? Like a bag that filters soybean milk, the soybean milk flows away, and the rest is bean dregs? ; Is anyone here? Like an hourglass of time. It was filled with water and flowed out, leaving no scars at last? ; Is anyone here? Like a sponge, everything is absorbed, squeezed, and what comes out is intact, even dirty? ; There are others? Like a drudge in a gem deposit, throw the slag aside and pick up pure gems? . This metaphor is very appropriate and enlightening. Some people can't read Accept an appointment? Tao, or like? Bags? , take the rough and extract the fine; Still like it? Hourglass? , leaving no trace; Still like it? Sponge? , absorb everything. You can imagine the effect of reading like this. We should study like drudgery in a gem mine, find out the defects and eliminate them? Slag? , only take gems. Extensive reading: refers to reading a lot, reading a lot and understanding things; About taking: refers to slowly taking out a small amount.
