I visited my aunt in a countryside near the city last week. I was surprised to see that great changes had been taken place in the countryside. Take my aunt's family for example. They supply preciously trees and flowers to the stores in the cities and have over ten workers working for themselves. Their family's income reached as much 100,000 yuan last year. Not only did they have a house, a car and computers, they can also afford a trip abroad every year. When asking what else they needed most, they said that they wanted to learn a few English so that they could do business with foreigners directly. To their delighted, my cousin can use he has learned from university to help them with overseas trade.
