"Every man is responsible for the rise and fall of the world." This famous saying was first put forward by Gu, a patriotic thinker and famous scholar in the late Ming and early Qing Dynasties.

Gu studied hard since he was a child. Enlightened at the age of 6, 10 began to read history books and literary masterpieces. 1 1 years old, his grandfather Li asked him to finish the History as a Mirror, and warned: "Now some people just browse the outline and other books to save trouble, thinking that everything is fine. I don't think this is worth taking. " These words made Gu realize that reading and studying is an honest thing and must be treated seriously and faithfully. Gu Qin was diligent in reading, and he adopted the measures of "self-examination reading": First, he set himself the number of volumes that must be read every day; Secondly, he limited himself to copying the books he finished reading every day. After he finished reading Purple Tongzhi Sword, one book became two books. Third, ask yourself to take notes and write down your experiences every time you read a book. Some of his reading notes were later incorporated into the famous book Rizhilu; Finally, every spring and autumn, he will review the books he read in the first half of the year, read them silently, and ask people to read them aloud. If differences are found, he will check them immediately. He stipulated that he would spend 200 pages a day like this and never rest until he finished reviewing.
