The change brought about by the Internet is revolutionary. The change involves not just good but also bad outcomes such as online gambling. The gambling net in cyber space, not limited by physical constraints, involves hundreds of thousands of people and billions of yuan.

The largest Internet gambling case, which China's public security department cracked, involved six rings of tens of thousands of gamblers and agents. The money involved is as much as 50 billion yuan ($7.3 billion) and the illegal gains confiscated exceeded 800 million yuan ($117 million).

Traditionally, gambling is considered a major source of evil: it arouses people's greed, breeds crime, and, when gamblers have lost everything, makes robbers and thieves of them. The gambling business makes money by exploiting an intrinsic human weakness.
