The spring rain moistens things silently. The establishment of the emotional bond between teachers and students enables teachers to accurately grasp the pulse of students' thoughts, such as why they are tired of studying, why they are addicted to internet cafes, why they run away from home and other psychological problems that can not be solved for a long time in the original school, and all of them can be quickly solved through sincere communication between teachers and students and sincere guidance from teachers. First, special education targets meet the needs of students, parents and society. At all times, education is based on achievements; Xu Xiangyang, on the other hand, changed from choosing the best to choosing the worst, which created the precedent of choosing the worst education in China and became the educational highlight of the world because of the particularity of the educational object. As we all know, traditional education characterized by exam-oriented education is like a huge machine that keeps running. While constantly cultivating a batch of outstanding students, it also produces a batch of "poor students". These minors are difficult to learn by themselves, to be taught by teachers, and to be managed by parents, which has become a worry for teachers and parents. If they are not educated in time, they will also become a hidden danger in society. However, traditional education is limited by its own system and management mechanism and cannot solve this problem. At this time, the selective education initiated by Xu Xiangyang came into being naturally and inevitably, which filled the gap in education, brought hope to "poor students", brought good news to parents and brought benefits to society. Therefore, selective differential education conforms to the needs of contemporary education, students, parents and society, and its roots are deeply rooted in the fertile soil of society.
