From 65438 to 0985, after several changes, Yu Yi took the post of principal of Shanghai No.2 Normal School in a healthy spirit. It was a devastated school at that time. Stepping into the school gate, Yu Yi saw dilapidated school buildings and scattered teachers. Yu Yi made a series of decisions that shocked the society at that time: teachers practiced shift system, and students cut their hair and wore school uniforms. And resolutely face all kinds of discussions inside and outside the school; What society allows, schools can't all allow; What is popular in society is not necessarily advocated by schools. She began to educate two generations of teachers' morality, invited retired cadres to do revolutionary traditional education, invited blind bands to tell how to be strong in life with wonderful performances, and invited teachers and students to discuss the images of contemporary teachers and normal students. It is planned to build a library experimental building, a gymnasium and an art building, open up a large lawn and plant trees and flowers, so that the school will have flowers in spring, shade in summer, fruit in autumn and green in winter, and become a pure land for educating people. Yu Yi has many dazzling honors: national model teacher, national excellent teacher worker and national model worker. But the most precious thing is the eternal teacher.
