I visited my aunt in the countryside near the city last week. I was surprising to see that great changes had been taken place in the countryside. In the past they were poor due to the lack of knowledge and experiences. Despite the fact that they spared no efforts to search of every possible means to make money, which seemed that all they did was in vain.
Now their family’s income reaches as many as 100, 000 yuan each year. Not only they have a house, a car and computers, they can also afford a trip abroad. When asking what else they need most, they said that if they have learned a little English , they would have been able to do business with foreigners directly. To their delight, my cousin can use that he has learned from university to help them in overseas trade.
