When it comes to the campus security, we have to take it seriously. It was reported that a school stampede in Kunming City had caused several deaths and injuries at a local primary school on September 26^th, which again shocked the people all over the country.

I felt very sorry about it. The stampede accident left me deep in thought. As students, what should we do to avoid it in future? Here are some tips.

Firstly, don’t rush out at the time after class or school. You’d better wait to leave until there are fewer people. Secondly, learn to walk on the right side when walking with a crowd of people. Stay alert and watch your steps. Besides, stand still and try to hold on to something when there is pushing and squeezing. Last but not the least, once a stampede happens, you should curl up your body and bend your legs to protect your organs.
