In addition to teaching in the classroom, primary school teachers also have to prepare lessons, correct homework, manage students, etc. Therefore, the national education department stipulates that the class standard for primary school teachers is generally 14 to 18 lessons per week. , an average of 3 to 4 class hours a day, so as to ensure that teachers have time to prepare lessons, correct homework, discover problems in students' learning, and better guide students after class.

However, in some primary schools or teaching sites in remote rural areas, due to insufficient teaching staff and insufficient number of teachers, and at the same time, in order to complete the teaching tasks, teachers often have to "do a lot of work". Work at full capacity all day long. For example, some rural primary school teaching sites only have three grades: first, second and third. There are only three teachers in the school, "one carrot and one pit". There must be a teacher in each class of the three classes, which creates The three teachers work almost around the clock.

In terms of course arrangement, there is a morning reading class in the morning, followed by three main classes; there are also three classes in the afternoon, totaling 7 classes a day, so each teacher has 35 class hours. Sometimes labor, art, physical education, music and other courses will be taught by students of multiple grades together, so that teachers can be freed up for occasional turns.

Even so, each teacher still has more than 30 classes. Many teachers have been teaching in remote schools or teaching sites for three to five years, or even longer. They are silently dedicating their youth to the development of rural education, which is admirable!
