What do you think of primary school? In class, some students raised their hands to go to the toilet, and then the math teacher said: lazy people shit more! And then the whole class laughed?
Because generally speaking, there is a rest after class, which is used to go to the toilet to drink water. Students go to the toilet, which disturbs the classroom order and interrupts the teacher's thinking. If you want to study hard, you have to sit and study for a long time A tomato clock is to concentrate for 25 minutes and rest for 5 minutes, so don't blame the teacher and be a good student who abides by classroom discipline.
