The students let the teacher lie on the table, tied the teacher to it with a rope, and gave the teacher a ball. This posture is uncomfortable, and the teacher's saliva is constantly flowing out and struggling. Then the student hung the teacher to punish him. The teacher was tied with a rope and had difficulty breathing. In the end, the teacher was tied to the pillar, his hands tied behind his back, and he hung his hands high, the teacher to drop his head. The teacher could not hold on, and finally begged for mercy.
