What does it mean to "distinguish it by consciousness, and then understand its meaning"?

I judge the difference according to the meaning of the text (where there should be a pause), so I know the general idea of the Book of Songs.

This sentence is from Ming History.

Original: Chen Jitai, born in Linchuan. The family is poor, can't learn from the teacher, and has no books. When I take books from the side, I will read them secretly. The Book of Classics, which I got from my brother, has lost its four corners, and there is no sentence to read, so I distinguish it by consciousness and understand its meaning. At the age of ten, I saw the Book of Songs in my family's medicine cage and scurried away. When my father saw it, he was angry, and when he went to the field, he took it to the field, where he lived on high mound and never forgot it. After a long time, I returned to Linchuan, and I became famous in the world with Nanying. It is very sensitive, and it can be twenty or thirty songs a day, and it has made ten thousand songs. There is no one who is rich in life and career.

Chen Jitai is quick-witted and writes very fast. Sometimes he can write twenty or thirty articles a day, and there are as many as ten thousand articles in his life. History books call him "a rich man who has made a fortune through his life, and there is no one who has been successful in his career." He is highly accomplished in eight-part essay. He integrated the ancient books of classics and history, created his own way, made use of the topic, hired talents and expressed his opinions, and was called an eight-part essay master.

In the twenty-four histories, The History of Ming Dynasty is praised by historians for its proper compilation, informative materials, steady narration and concise writing, and it is a high-level historical book. This reflects that the editors have reached a high level in the examination and revision of historical materials, the use of historical materials, the mastery of historical events and the mastery of language. * * * Twenty-four volumes, in terms of the number of volumes, the chronicle of Ming History accounts for less than one-tenth of the book, and in terms of the number of words, it accounts for less than one-fifth of the book. From this, we can see that the proportion of biographies in the History of Ming Dynasty is very small, which is a feature of the compilation style of the History of Ming Dynasty. In biographical history books, this chronicle is a part of the narrative history in chronological form. Obviously, History of the Ming Dynasty takes this chronicle as the outline of the whole history, and it is listed before the whole book in a concise way, so that people can first understand the general situation of the history of the next generation when reading this history book, instead of making people know everything when reading this chronicle. This should be regarded as the originality of the overall design of the compilation of Ming History.
