Senior one and senior two are not divided into majors. More than 200 students were divided into nine classes, two of which scored high in the exam, class 6 and class 9 respectively, but they were kept secret at that time. Students don't know their exam results, and they don't know which class has the highest exam results. I was assigned to Class 6, and it took me two years to know that this was a class with high test scores. The most outstanding achievement of Class 6 is Chen Tianquan, who was admitted to Shanghai Middle School. During middle school, he studied some college courses and was able to read math books in English and French. In the math analysis exercise class, he often finishes the problem quickly, and the exercise teacher Wu Wenda gave him another problem, which was biased. Once in the class of analytic geometry exercises, he came up with a strange trick to make the result of an exercise extremely concise. Teacher Cheng Qingmin was surprised. After thinking for a moment, he affirmed his result and praised it. Chen Tianquan published a paper in the second grade. I remember that the topic is Riemannian integrability on typical topological domains, and the contents of the paper are all things that I haven't learned in the course. Mr. Cheng Minde later recommended it to other professors and commented that "Chen Tianquan has mastered all the basic knowledge in related fields". After graduation, Chen Tian was all assigned to Inner Mongolia University. After the reform and opening up, he resumed his degree. Became the first doctoral supervisor in Inner Mongolia Autonomous Region, and then transferred to Tsinghua University to teach.
