When I was studying, the teacher had a history lesson-The Spring and Autumn Period of Sixteen Countries, in which many names of Hu people were as difficult to remember as those of foreigners, so remembering names became a stumbling block in the history lesson at that time. In order to overcome this difficulty, one day, Guo Moruo made an appointment with a good classmate and hid in a dark study room. The two of them studied hard and played a game until they memorized the whole history textbook.

In the later days, even during the annual leave, Guo Moruo insisted on studying hard every day. During the annual leave of one year, he read the Historical Records written by Sima Qian from beginning to end, analyzed, revised and evaluated them one by one, and made notes beside them. Even in "Biography of Boyi", there is a sentence that was misinterpreted by the annotators of past dynasties, and he found and corrected it in the process of reading. Guo Moruo regarded some incisive remarks and rare materials as treasures, and spared no time and energy to copy them down with a brush, put them on his desk and read them at any time.

Guo Moruo wrote many poems and articles about the great wealth in his life. But he has a writing habit, that is, he never asks others to copy it for him, but always does it himself. Even in his later years, when he was nearly 80 years old, he wrote the book A Study of Li Bai and Du Fu. Because of poor eyesight, someone suggested that others copy it, but he still disagreed. Many of his books have been changed several times before and after, and he carefully pondered, tempered, revised and copied word by word.

Hua is a famous mathematician in China. He studied hard since childhood and became a famous scholar.

1950 In February, Hua quietly boarded a small mail boat with her family and left the United States where she had lived for four years. When he set foot on the land of his motherland, the radio broadcast his Open Letter to American Students. The letter wrote emotionally: "Although Jincheng is not as happy as going back to his hometown, Xanadu is good, but it is not a place to live for a long time, so come back!"

Hua returned to Tsinghua University as the head of the Department of Mathematics. Soon, he was appointed as the director of the Institute of Mathematics of China Academy of Sciences. He cherishes the great time provided by the party and the state for scientific research. He goes to school with crutches during the day, uses a chopping board as a desk at night, does math research under the lamp, and often writes late into the night. Sometimes, in order to prove a problem, he often gets up late at night, picks up the newspaper at the beginning of the morning, and makes calculations and arguments in the surrounding blanks. In his room, on the desk, on the bed and on the floor, there are piles of calculus papers everywhere. He weaves success and honor with perseverance and diligence.
