     A little knowledge can make a difference at a time of life or death. Do you know what

to do if you find yourself in an earthquake?

If you are inside: 

● Quickly move under a strong desk, a strong table or along a wall. You can also go into

a small room like the bathroom. This will protect you from falling things.

Do not get into a lift.

● Don't stand near windows, large mirrors (镜子), heavy furniture or fireplaces.

If you're outside:

● Move away from buildings and streetlights. These could fall on you.

● Squat (蹲下) and protect your head until the shaking stops.

After the earthquake: 

● Check, take care of injuries and help make sure people around you are all right.

● Watch out for aftershocks.

● Protect yourself by wearing long pants, a long-sleeved (长袖的) shirt and strong shoes.
