One grade is divided into three grades, two in the new school and one in the old school. Relatively speaking, the proportion of children outside the city in the new school is higher, that is, the proportion of children coming in from the old school is higher, there are more children in the old school, and there are more people looking for the relationship with the old school. Because we all want to go to the old school, the children in the new school feel that they can work harder, so the academic performance in the new school is higher than that in the old school. In teaching, the teaching style of the new school is more open, and the tradition and atmosphere of the old school are stronger. There is no difference in management. The accommodation in the new school is better, but there is no heating in the dormitory. In terms of diet, the old school canteen is small, and children who go to school often can't eat.
