Wu Keda stabbed student librarians（武科大图书馆管理员砍杀学生）

Today, I saw a harrowing news: Wu Keda Castle caused a campus librarian who divides students died. Event is roughly the following manner: October 20 9 am, Wuhan University of Technology Library, 5th Floor, a self-study room, a 38-year-old male librarian began to sing the same song over and over again, breaking the quiet atmosphere. A student asked him not to sing so as not to affect your learning.Surprisingly, the administrator suddenly fly into a rage, pulled out a fruit knife, against the will of a boy and a girl stabbed. More than 20 knife cut the girls, leading to death of girls, boys were injured. Down in a pool of blood after the two students, administrators and stabbed himself in the abdomen, also while shouting "I do not tell you that." The suspect is said to be suffering from mental diseases.
 I also as a university teacher, first of all live life to the passing deeply regret. The behavior of such strongly condemned. Bitter experience, I think we have to think: Wu Keda librarians student stabbed the real source of tragedy, what is?

今天，我看到一则让人心痛的消息：武科大青山校区图书馆管理员砍杀学生致1人死亡。事件大致经过是这样的：10月20日上午9时许，武汉科技大学图书馆5楼一自习室内，一位38岁的男性图书管理员开始反复地唱同一首歌，打破安静气氛。有学生要他不要唱歌以免影响大家学习。谁知该管理员突然暴跳如雷，掏出一把水果刀，对着一名男生和一名女生便刺。砍了女生20多刀，导致女生死亡，男生受伤。两学生倒在血泊后，该管理员又用刀刺伤自己腹部，还一边喊着“我看你出不出来”。据说疑凶患有精神性疾病。

我同样身为大学老师，首先对逝去的鲜活生命深深地感到遗憾。对这样的行为表示强烈的谴责。痛定思痛，我觉得，我们不得不思考：武科大图书馆管理员砍杀学生惨案的真正根源是什么?
