Adultery and corruption in China

As China prospers, it is seeing a resurgence of the common problems of a rapidly prospering society. The incidence of corruption in the society has increased rapidly to the extent that it is impacting the growth; China has launched a major campaign against corruption and is cracking down severely on corruption (with death penalties being enforced for people caught in corruption cases). The other major issue that has surfaced is that many of these richer people have adopted the practise of having mistresses. The Chinese Government seems to have tried to break both of these tendencies by using one against the other:

Corruption and mistresses don't make good bedfellows. Authorities in southern China are using information obtained from mistresses of government officials to crack down on corruption, state media reported Thursday. At least 80 percent of government officials arrested for corruption in the city of Dongguan in Guangdong province were exposed thanks to their mistresses, the China Daily said.
Beijing has been trying to rein in corruption for several years. A law that went into effect last year mandates that government officials found to have mistresses be dismissed from their posts. In recent years, the country has seen several highly publicized corruption cases involving officials who steal -- in part to provide for their mistresses.

Seems like an interesting way to ferret out this information; it also seems to be apparently working.
