1. In the stairs, people should behave in a civilized manner when going up and down the stairs. When there are many people, don't crowd, boo and fight, and don't make strange phone calls on purpose to create an atmosphere of tension or panic. 2. Students who go downstairs try to avoid the crowded crowd and try to walk on the edge of the crowd when they have to. 3. When you find a crowded crowd coming in the direction where you are walking, you should avoid it immediately, don't panic, don't run, and avoid falling. 4, go with the flow, don't go with the flow, otherwise it is easy to be pushed down. When you or the person in front suddenly falls down, you should call for help immediately and tell the person behind you not to approach forward. 6. If you are unfortunately overwhelmed by the crowd, try to get close to the corner, curl your body into a ball, and buckle your hands behind your neck to protect the most vulnerable parts of your body. 7. If you are trapped in a crowded crowd, you must stand firm first. Don't lean and lose your center of gravity. Hold the wrist of the other hand with one hand, spread your elbows and lay flat on your chest. Lean forward slightly to form a certain space to ensure smooth breathing and avoid suffocation and fainting when crowded. Don't bend down to pick up your shoes or tie your shoelaces even if your shoes are trampled off. If possible, grab something solid and reliable and walk slowly or stop as soon as possible, and leave the scene quickly after the crowd passes.
