Reading could help a person broaden their horizons, improve their knowledge, train their thinking ability and reading comprehension ability, thus increasing their personal content and cultivation, and improving their temperament. By reading different types of books, a person can understand different life experiences and ways of thinking, so as to better understand themselves and others and improve their social skills. However, it was not necessarily possible to change a person's temperament just by reading books. Temperament was a complex concept that was influenced by many factors such as genetics, environment, life experience, and so on. Therefore, even if reading books provided a lot of new knowledge and enlightenment, there was no guarantee that it would definitely change his temperament.
