When Pressed Down

　　After major earthquakes, aftershocks may happen. The situation may become even grave. One must improve the situation he is in and manage to keep away from dangers. Keep away from unsteady or collapsing objects, suspending objects and other dangerous objects; move away the debris and enlarge the space around one. Note: don't move anything forcefully, so that the person buried down won't invite further collapses; manage to support the collapsed walls with bricks so that one won't be pressed down again during the aftershocks; don't use indoor facilities casually, including power, water sources etc; don't use open fire; cover the mouth and nose when one smells the flavor of gases or toxic gases; don't shout aimlessly, keep energy, ask for rescue through knocking.
