First of all, from the perspective of education, spring and autumn holidays can provide students with richer learning opportunities. At present, the curriculum content of primary and secondary school students is heavy, and students need to spend a lot of time on their studies, mainly during the semester. If the spring and autumn holidays are added, students can participate in various forms of extracurricular activities, such as popular science education, social practice and artistic experience, which will help improve students' comprehensive quality and practical ability and better cultivate their all-round development.

Secondly, from the perspective of students' physical and mental health, spring and autumn holidays are also necessary. Nowadays, students spend most of their time in a state of intense study, both physically and psychologically. If there is not enough rest time, it will lead to physical and mental fatigue, inattention and other problems. The increase of spring and autumn holidays can give students more time to relax, rest and participate in various activities that are beneficial to their physical and mental health, which is helpful to promote the all-round development of their physical and mental health.

However, the joining of the Spring and Autumn Holidays will also bring some negative effects, the most obvious of which is the lag of teaching progress. The increase of spring and autumn holidays will interrupt the teaching progress, and students need more time to adapt to the learning state, which is not conducive to the tense teaching progress. At the same time, the increase of spring and autumn holidays will also bring some time burden to students, especially for those students who need to make up lessons, this holiday needs more time to make up lessons.

So, on the whole, I think it is necessary to increase the spring and autumn holidays. Although the increase of spring and autumn holidays will have a certain impact on the teaching progress, in the long run, it will help to improve students' physical and mental health and comprehensive quality. At the same time, in view of the negative impact of the Spring and Autumn Holidays, we can strengthen the quality of classroom teaching and take various measures to make up for the lag of teaching progress.
