In terms of work intensity, middle school teachers are definitely more tired than primary school teachers, because the schoolwork tasks in middle schools are heavier and the teaching pressure is greater.

In terms of work difficulty, middle school teachers will be heavier than primary school teachers, because junior high school children will be in a rebellious period and more difficult to discipline besides teaching.

In terms of working hours, primary schools usually finish classes at four or five. At this time, if there is nothing else, the teacher can get off work, but middle schools often study by themselves in the morning and evening. Basically, self-study in the morning is after 7 o'clock, and self-study in the evening will last until 10, which consumes the teacher's energy.
