Students' academic performances is mostly determined by students themselves rather than the teaching quality of teachers, so basing their salary on students score is unfair. It is common that students who have the same teacher and the equal class hour achieve distinctive academic scores, with one students being the top students among the class and the other being the last among the whole grade. Therefore, students' exam results have little or even nothing to do with the teacher himself because they are mostly depend on the student himself.

It may even trigger the exam-oriented exam. A teacher's duty is far from just imparting knowledge. They are also mentor for the young generation, teaching their moral principles and how to be a good person.

A survey was conducted by a Chinese newspaper agency to learn about the current situation of the students with the highest score in the college entrance exam in ten years. To the reports surprise, none of them have achieved anything. A complete tragedy of exam-oriented education. Also, the
