Reading is, of course, word by word, and reading one line at a time is definitely not acceptable. A history book should be read at least once. I remember when I was in the fifth grade of primary school, I read a young version of the general history of China at least seven or eight times. At school, all my extracurricular books were history books, such as global history, European history, financial history, World War II history ... Reading history makes people wise, and I hope you can do the same. Hope to adopt.
