First, quantity: reading and memorizing the prescribed learning content according to the prescribed time is called "quantitative" reading method. Xu Teli studies very hard. He never reads all the lines and gulps them down. Instead, chew it like an olive, savor its taste, and understand the idea, layout and writing skills of the article. For example, when he studied Shuowen, he suffered from the difficulty of remembering seal script. He made it a rule to learn a few words every day, write them in his hand before going to bed at night until he became proficient, and at the same time think about the meaning of the words. He often said: "reading is unrealistic and insatiable, and he can neither understand nor remember." If you want to remember on the basis of understanding, you must be regular and do what you can. "
Second, perseverance: that is, study hard and persevere. He often walks, wakes up at night and keeps on studying. Usually, he always copies famous sentences extracted from books such as Chinese, history and nature into cards and puts them in his pocket. I take them out to read and remember as soon as I have time. Over time, almost all the contents in these books can be memorized. What's more, he began to teach himself a foreign language at the age of 60. After several years of hard work, he finally learned the languages of Britain, Russia and Japan.
Third, diligence: as the saying goes, "a good memory is not as good as a bad writing." Xu Teli took notes on key paragraphs and sentences in the book, some circled the book, some memorized it, and accumulated dozens of reading notes over time.
