Summary of the story of Qian Xuesen, the father of Chinese missiles;

In the library of Jiaotong University, there is a 96-point hydraulic test paper, which was made by Qian Xuesen. After such an ordinary test paper, there is a touching story. It turns out that when Qian Xuesen was studying at Shanghai Jiaotong University, his personality and study were excellent, and he got more than 90 points in all subjects.

In a hydraulics exam, Qian Xuesen answered all six questions correctly. His teacher, Mr. Jin, was very happy and gave Qian Xuesen a perfect score of-0/00. However, Qian Xuesen found that he mistyped a symbol "Ns" as "N" when answering questions. Qian Xuesen took the initiative to tell the teacher about this small mistake, and the teacher also changed the test paper of 100 to 96.

Teacher Jin has always kept his disciples' test papers in his suitcase, even during the war and migration. When Qian Xuesen returned to his alma mater in the 1980s, Mr. Jin took out this precious test paper and gave it to his alma mater. This small test paper also reflects a world-famous scientist's strict requirements for himself, meticulous in learning and scientific research, and open-minded and upright.
