Tong Dizhou studies hard. At the beginning, the school was not allowed to read in the classroom. He looked under the street lamp. The foreigner said that he could not do the experiment. After many experiments, he succeeded and won the praise of the professor.
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.
