Stampede accidents have always been the most common on campus. Successive stampede accidents have stung people's eyes again and again. From June 5438 to February 2009, a stampede occurred in private Yucai Middle School in Xiangxiang City, Hunan Province, causing 8 deaths and 26 injuries. Why is this happening? It was because a student bent down to tie his shoelaces at that time that the people behind him pounced on him, which caused such serious consequences. Small hidden dangers that often seem inconspicuous, due to lack of safety awareness, can lead to such a big disaster. Security should not be underestimated. In addition, in "Seeking Truth from the News", a demonstration was specially made for us, telling us to protect our head and chest when we fall. In the demonstration, the balloon was used to simulate our most vulnerable chest in the stampede accident. As long as we don't have any protective posture, as long as our bodies are squeezed, balloons will burst. Similarly, if it is our breasts, it is likely to be life-threatening. So pay more attention to safety and don't waste your life in vain.
