After Reviewing the Essay, I Found Out the Death of Someone Three Years Ago

Chinese teacher Chen Mo discovered a murder in his composition. The student described in detail how a girl at the same school was bullied to death three years ago. The deceased was the biological sister of Su Qing, a transfer student in his class. When he started to investigate, the principal handed him a thick red envelope: "Teacher Chen, let the past pass quietly. This is the 'rational kindness'." The mother was seriously ill and needed money urgently, and the reporter's fate - the crazy former head teacher Shen Xiao, was still muttering to himself in the mental hospital. But Su Qing put her sister's blood-stained diary on his desk. Turning to the last page, there is only one line: "Teacher Shen, do you also want me to disappear?" Now, with ironclad evidence in hand, Chen Mo walked to the podium for the school-wide open class. The lights came on and he whispered into the microphone: "In today's class, we are going to read a...'Murder Essay' written three years ago."
