Mary: What should I do if I get troubled in China ?
Lilei: In China , when you in trouble, you can call 110 for help. The policeman will arrive in the first time. When your neighbor's house is on fire, you must call 119. When you call 120, an ambulance will come.
Mary: Wow, the emergency numbers are not the same as our country.
Lilei: Really?
Mary: In American, the emergency number is 911. It provides comprehensive services, including police, fire and ambulance.
Lilei: It's more convenient than China . You needn't remember so many numbers.
Mary: You are right. As far as I know, the emergency numbers are different in different countries. In England , it's 999 and it's 000 in Australia .
Lilei: That sounds interesting. But they are all very easy to remember.
Mary: And the calls are for free.
