On June 15, 2017 (May 21, 2017 in the lunar calendar), Xuzhou kindergarten exploded. At 16:50 on June 15, 2017, an explosion occurred on the east side of the gate of Chuangxin Kindergarten in Feng County, Xuzhou City, Jiangsu Province.

On June 16, the case was solved, and the alleged offender Xu Moumou was killed on the spot. The Ministry of Public Security working group, together with the local public security organ, identified Xu Moumou, male, 22 years old, from Quanshan District, Xuzhou City after on-site investigation, investigation and visit, video surveillance retrieval, physical evidence inspection and DNA comparison. After Xu Moumou was suspended from a school due to autonomic nerve dysfunction, he rented a job near the crime scene. Homemade explosive device materials were found in his rented house, and words such as "dead", "dead", "extinguished" and "absolutely" were left on the wall. It took less than 24 hours from the incident to the crack. Here, I pay tribute to all the police officers who are fighting on the public security front! The cause of the explosion in the kindergarten was exposed. TA said famous comments. On June 15, 2017, a serious explosion occurred outside a kindergarten in Feng County, Xuzhou, Jiangsu. The explosion killed 8 people and injured 65 others. This vicious incident immediately aroused great attention from all walks of life! The national level has always paid attention to the personal safety of minors. Since these years, some criminals who hate society have chosen to take revenge on students on campus, and bloodshed is not uncommon. In this regard, setting up police officers on campus during the school day also plays a certain preventive effect. However, how to prevent bloodshed from happening again, the focus is not only on campus, but also outside the school. Some netizens suggested that the relevant state departments immediately carry out a large-scale investigation of potential safety and health hazards around the campus. Education, industry and commerce, health, fire protection, urban management and other departments cooperate with each other. They feel that although doing so for a long time may cost the people and even waste administrative resources, it is okay to occasionally do it once or twice. - From a famous online commentator and columnist: Lu Guoping is now self-media developed, and as soon as an emergency occurs, everyone has it on their mobile phones, as if the incident happened on their mobile phones. But the fatal injury of self-media is that the information is inaccurate. In this incident, self-media initially only said that the Xuzhou kindergarten exploded, and after a while, it was mentioned in Fengxian County, and said that it happened outside the kindergarten, and the cause of the explosion: the explosion of the gas tank at the food stall, and said that this was the statement of an anonymous official of the Xuzhou Municipal Party Committee Propaganda Department. But the official Weibo "Xuzhou Release" did not have such a statement, and the vice minister of the Ministry of Public Security immediately led a team to Fengxian County to "guide the work", indicating that the officially known incident was by no means a safety accident like the explosion of the gas tank. - From scholars and media people: Cheng Helin
