When I was in junior high school, I was lucky enough to attend a teacher's math tutorial class. His teaching purpose is to cultivate students' mathematical literacy and independent thinking ability, but I can't find her contact information. (It should be a well-known retired teacher. At that time, a large class taught 100+ people and there were 6 classes. Counseling targets are junior high school, senior one, senior two and senior three. )
I am a student in Xinxiang No.2 Middle School. Currently studying mathematics at Hangzhou Normal University.
