There are about 600 to 800 stories about Sue's hard study.

At the age of 9, Su's father took a cart of rice as tuition, walked 50 kilometers of mountain roads and sent Su to Pingyang County, where he became a high school placement student. From the mountainous area to the county seat, Sue is really an eye-opener, and everything is novel. When he first saw the minced meat in the steamed bread, he often changed his meal ticket into money to buy "meat steamed bread" to eat. A month's meal ticket has been used up long ago, so I have to go hungry.

When he saw the tiger stove boiling water, he felt very interesting. He threw the eggs he brought from home into the pot, and a pot of boiling water turned into a pot of egg drop soup. The boiler man was so angry that he grabbed him and hit him Sue plays all day and often sits at the top of the list. At the end of the final exam, he came last in the class. However, his composition is not bad, and he "eavesdropped" in a private school.

It stimulated his interest in Chinese and laid a little foundation for his composition. However, the more Chinese teachers read, the less they think Su's composition is plagiarized. Therefore, he was awarded a low score. In this way, his stubbornness was even more aroused. The more the teacher says that he is not good, the less he studies hard. For three consecutive semesters, he was the last one. Besides, the teacher said he was a "fool".

Once, the geography teacher Chen Yufeng called Su to the office and told him a short story: "When Newton 12 years old, he transferred from a rural primary school to a city to study. This is not good, and his classmates look down on him. Once, a classmate bullied him rudely and kicked him in the stomach. He rolled in pain. That classmate is better than him in health and homework, and Newton is afraid of him at ordinary times.

But at this moment, he couldn't bear it, jumped up and fought back, forcing the classmate into the corner and pressing it against the wall. This classmate saw that Newton was furious and had to give in. There are only so many reasons for Newton to learn from this incident: as long as he makes up his mind, he can subdue it. He studied hard and soon became the first in his class, and later became a great scientist. "

Sue is grateful to Mr. Chen for not criticizing him and telling him stories. Teacher Chen saw him hang his head, touched his head and said, "I think you are fine." As long as you are willing to work hard, you will definitely get the first place. " He added: "You, work hard, scrimp and save, and you read the book well. What will you repay them like you in the future? " Sue couldn't hold back her shock any longer.

Tears dripped on my chest like broken pearls. For the first time, I felt that I had done something wrong. Since then, he has completely become a sensible child, stopped playing, studied hard and won the first place in the final exam.

Su, who founded China School of Differential Geometry, opened up a new direction of computational geometry research in his later years.

He has made outstanding contributions to affine differential geometry, projective differential geometry, general spatial differential geometry and projective yoke network theory, and established the internationally recognized China School of Differential Geometry. At the age of 70, a new research direction of computational geometry was founded and started in combination with solving the practical problems of mathematical lofting of ships.

Su's research direction is mainly differential geometry. Most of Su's research work belongs to affine differential geometry and projective differential geometry. In addition, he also devoted himself to the study of general spatial differential geometry and computational geometry. He founded the internationally recognized School of Differential Geometry of Zhejiang University.
