Guangzhou is a capital city of Guangdong province. I remember last time, there was a thief stealing money from a people in the bus. The bus driver noticed this situation, he closed the door and called the police. It means he protected people's money. Even you are alone when you are got trouble, you also can all the police in hotline 110, they you will find you and help you.   Si cuan is a place where earthquake often appear in China. Scientists developed a program to help people. It can countdown of 10 seconds advance to warn people. You can know this information from your computer, cell phone, even where you live where there will be a broadcast to inform you. It give a few time to people for save themselves.   Young people go for work around 8:00 am every day. Many people go to bus station and subway this time. But you will also find that many old people go for tea by transportation in the same time. Young people need to go for work on time, otherwise they will lose money because of late. If old people can go out late a little bit will be much better, because they no need on time.   In last year, government announced a new rule about garbage. We need to sort the garbage to 4 types, such as recyclables, kitchen waste, hazardous waste, and other waste. We putted all garbage in the same box before. now we need to know which kind of garbage is belong which box, then put it in.
