First, the cause of the epidemic is well known, and the epidemic is highly contagious. Educational institutions are crowded places, and it is inevitable that teachers will vent their anger when giving lectures to students. If one of the teachers has an epidemic, then the whole class can't run away. Therefore, some parents temporarily prevent their children from attending various remedial classes for the sake of their children's health and safety, which is also one of the reasons leading to the closure of educational institutions.
Second, students object to the clear stipulation of the Ministry of Education that schools should attach importance to students' quality education, not just for grades. After the child enters adolescence, he has some aversion to learning. Parents may give their children various remedial classes, which may make them feel particularly distressed. Therefore, some children are unwilling to attend remedial classes, and choose to go out to play with friends after finishing their homework. They may think that their due tasks have been completed and don't want to add any additional tasks.
Third, parental factors Some parents are unwilling to let their children suffer. Students are very tired after a day of textbooks at school, and they have to attend remedial classes on weekends and sundays, so children will not have a day off in a week. Every child is the darling of parents, so some parents don't want their children to suffer so much. They don't want to raise their children too well, as long as they are in the upper middle class.
