Sue was born in a poor peasant family and entered a primary school as a drop-in student when she was a teenager. Due to his poor language ability, he ranked first in his class at the end of the semester. The next year, he changed to another school and became fluent in language. But I met a teacher who discriminated against children from poor families. He suspected that the good sentences in Su Bu's sketches were not written by himself, so despite the good sentences, he gave the group a "poor" word. This hit Sue's mind. He had an effective way to fight back, but he didn't attend class. As a result, I came last in the final exam. In the third year, he met an honest and amiable teacher, Mr. Chen, who had no discrimination against poor children. The teacher approached him actively, understood his inner anguish, patiently inspired and educated him to strive for a better future by relying on his inner efforts. The teacher also said, "I think your qualifications are not bad." As long as you work hard, you will definitely become a useful talent. " This gave him great encouragement. From then on, he began to concentrate on his studies. At the end of the school year, he won the first place in his class. Since then, he has been among the best in every exam. A few years later, he was admitted to middle school with excellent results. In the second grade, he met a teacher named Yang, and his math class was very attractive. This made Sue interested in mathematics. The teacher praised Su for his good foundation in arts and sciences and encouraged him to take the road of saving the country through science. With the guidance, encouragement and help of this teacher, Sue's enthusiasm and talent for learning mathematics were aroused. He solved a geometry problem in 20 ways, wrote a paper and sent it to the Zhejiang Student Homework Exhibition at that time. At this time, he met President Hong, who is also a geometry class. The headmaster Hong often watches Sue do her homework, nodding her head while watching, and always has a smile on her face. At this time, before leaving middle school to work in the Ministry of Education, the principal called Su to the office, encouraged him to study in Japan after graduation, and promised to give him help. Soon, I received a farewell fee from President Hong for 200 yuan, encouraging him to study hard for the prosperity of China. President Hong's financial support and spiritual guidance and encouragement became a turning point in Su's career. The three teachers Sue met were not only kind-hearted and did not discriminate against the children of the poor, but also very expert in cultivating talents. They all have an eye for talent. Teacher Chen saw at a glance that Sue's qualifications were not bad. They all cherish talents. Principal Hong gave Sue 200 silver dollars at a time. They are not only diligent and tireless in teaching others, but also know how to educate people. They can cultivate a young person's interest in a certain aspect. It can be said that if Sue hadn't met these three teachers, China today would be short of an outstanding mathematician.
