Andy was born in China 17 years ago. In 2007, she went to the USA with her family. As a high school student, she has found many differences between Chinese and Americans:
About money
Americans like to spend more than they have, so many of them are always in debt(欠债). But Chinese usually spend less than they have, so many of them always have money left in the bank.
The American kids themselves make their own money. Most Chinese kids always ask their parents for money.
