The 14-year-old Zhang Lei was riding home when a man suddenly jumped out from the roadside,
pulled him off his bike and rode to run off. Zhang was fairly scared, but he didn't run after the robber.
Instead, he found a telephone quickly and called the police at 110.
"Safety is the most important in such a situation, "Zhang said, remembering what his teacher had
told him in his first-aid class (急救课). "An adult is much stronger than you. It is not safe to run after
an adult."
Zhang is a student at Shenzhen Bao' an Middle School in Guangdong. His school is the first in China
to have first-aid education. The students at the school must take the class once a week.
Teenage safety has become a serious problem recently. According to a 2009 survey, about 16,000
teenagers die in all kinds of accident in China every year.
Bao' an School said that the first-aid classes are to teach students skills so that they can save
themselves in unusual situations.
Sun Yan, 12, described her favorite first-aid lesson."I performed as a stranger knocking at a door. A
classmate stood inside the door and asked several questions before letting me in. Then we changed roles
and did it again. "Sun said,"We learned a lot while having fun at role-playing."
"The teacher told us not to go out alone, especially at night. We would hit their eyes or noses if
someone tried to do bad things to us. Then we should quickly run into a crowded place," said Wang
Ying, a 13-year-old girl.
