The main reason for adjusting the class time in primary and secondary schools is to "reduce the burden on students". In recent years, the Ministry of Education has paid more attention to the sleep problems of primary and secondary school students. At the end of March, 20021,the general office of the Ministry of Education issued the Notice on Further Strengthening the Sleep Management of Primary and Secondary School Students, stipulating that the class time in primary schools should not be earlier than 8:20 and that in junior high schools should not be earlier than 8:00. Up to now, it has been implemented in some areas.
Starting from May 1, it is not necessarily a past tense to arrive at school at 8 o'clock. Because the Ministry of Education stipulates that the class time should not be earlier than eight o'clock, but the school generally requires students to come to school for self-study in advance. Therefore, the adjustment of class time in May 1 is not valid, and it is estimated that it will still be similar to the current class time. School classes are always at 8: 20 in primary school and 8: 00 in middle school, but don't forget to study by yourself early.
In short, the original intention of adjusting the class time in primary and secondary schools is good, so that students can have enough sleep. If you don't sleep well, it will not only affect your growth, but also make you feel bad in class.
