Chen Gang, a teacher of Polytechnic University, was defeated in a department-level cadre election and felt the darkness of society. He believes that universities should be the place where academics are supreme. It should not be the same as the power struggle in society, but should be based on the interests of students. Chen Gang himself is a very capable person, so he should not get used to this phenomenon in colleges and universities, and he wants to attract attention from all sides with his own death, so as to strengthen the management of colleges and universities.
