Gambling stands for any activity that gaining opportunity to win prizes.It can be classified into three models: lottery, hors-racing and casino.Although individual differences exist among three models, some similarities come with at the same time. The word ”gambling” presented at the first time according to the law of Macao, which were published in May 1982. Western nations and citizens are much familiar to gambling industry, thus it results in mature development. In the eastern society, however, gambling generates both sides of negative and positive impacts. As the results, the arguments occur in the society enormously. Few countries allow three models of gambling and few limit those all at once in the world. Most countries open the market for some gambling models partly and in the sequences of lottery firstly, horseracing secondly and casino finally. Due to the promotion of economics and production in late 20 century, people have open attitudes for gambling generally, even though it causes conflicts between governmental policies and civil cultures. Lottery and horseracing are able to raise funds for welfare at high percentages. In wealthy and multiple societies, gambling is acceptable easily; in contrast, it is difficult to be identified with those societies under the circumstances of backward economics, slow social mobility and high ethics. The latter are more lack of financial supports for developing welfare than the further.
