Du Yijun, a 21-year-old Fudan University student, was one of the 36 people who died in the crush on New Year's Eve on the Bund(外滩) in shanghai.
On the night of December31, 2014, a holiday celebration turned into a terrible tragedy. “Overcrowding(过度拥挤) and the failure of the police to contro1 the crowds were the main reasons it happened,” the authorities(官方) said.
For the last three years, light shows on the Bund have been successfully held for New Year's Eve celebrations, but this year the light show was canceled and there were fewer police on hand. But the crowds came anyway.  About 300,000 people were on the Bund by 8:30 that evening and more kept arriving until people suddenly became noisy and angry around 11:30. Some people fel1 on lhe stairs and were stepped heavily on and died.
In shanghai,the authorities have reacted(作出反应) to the Bund tragedy by canceling big events. But this isn't really necessary. Better planning and better crowd contro1 can make sure the celebrations are safe.
However, if you're going to a place where there wi1l be a big crowd, you should take notice of where the exits(出口)are, and if there are too many people, move away from the center of the crowd. And most importantly, if the crowd seems too big and makes you feel uncomfortable,,Just leave. No celebration is worth losing your life over.
