Jiangsu high school three-five-step jump is to concentrate five specific examination subjects in one week. This new policy has increased students' study pressure. This policy is formulated by the Ministry of Education based on the consideration of students' mental health, with the aim of reducing students' academic pressure and providing students with better rest and adjustment time. Due to the intensified competition for further studies, students study too much and prepare for exams too much, which leads to an increase in psychological and physical problems. Therefore, the Ministry of Education decided to put high school winter vacation ahead of time, giving students a period of time to relieve stress and adjust their state. Jiangsu decided to have a holiday because of five consecutive jumps. Five consecutive jumps, that is, five consecutive jumps during the winter vacation, are generally aimed at excellent universities or scientific research institutions.
