Nowadays, more and more people, especially in big cities, become interested in buying lottery tickets. According to chart 1, averagely 70 percent of those polled in the survey, held in three big cities, claimed to have dreamed of winning the big prize of five-million yuan. 85 percent of those polled in Guangzhou had had such a dream, compared with 65 percent and 60 percent, respectively, in Beijing and Shanghai.

The attraction of buying lottery tickets is obvious. The winner can get the biggest profit for the future with only a small investment. It realizes the beautiful dream of every participant-to be richer and to improve living standards. As is shown in Chart 2, should they win a big lottery, 81.3% of people would buy a new house, 61.9% would buy a car, and 61.7% would save the money for the education of themselves or their kids. And a great proportion of people say they would put the money in the bank or use it for investment or touring. Despite all the attractions brought by the lottery buying, it has also come under criticism. Some regard it as a kind of gambling, which is a potentially addictive behaviour.

In my opinion, buying lottery tickets is not so bad as some people think. Instead, it is good for society by creating new jobs and representing an important source of income for charity and sports causes. Of course, it is not a means of making money for individuals we should encourage, because the result is hardly predictable. Therefore, we should take a positive but cautious attitude towards lottery buying behavior.
