Yesterday, a concerned parent told Liaoshen Evening News that he placed a tape recorder in his son's pencil box to help his son in study. But on the tape, the teacher is caught making degrading remarks to her students for as many as 29 times. The relentless insults continue and don't stop at the students. The teacher also insults their parents.
Is this an individual incident, or is there a bigger problem? Why did the incident happen?
