It's along the same lines but DNA sequencing has very serious consequences in countries that have a history of strict filial piety such as China.

In these countries a family is not just the basis for raising children - families can often act as a sort of "corporation" where everyone is cooperating to enhance the wealth and future prospects of the group.

There was a lot of confusion around family relationships during WWII with the occupation of the Japanese and again after WWII with the Chinese Communist Revolution as children were adopted when their parents went missing or were killed in the war.

If people inside a family are found not to be related to one another there's a serious potential for the social fabric to start breaking down.

Widespread paternity testing will destroy the social fabric of China?

That's quite a stretch.

"destroy" might be an overstatement, but reproduction is _very_ important to people and changes in its dynamics have large ripple effects

look at birth control for an example

AFAIK, the family unit there is not so strictly around genetic lineage. I could adopt a child in with the intention of having him be my successor. He is my son then, without the genetic lineage.

Hell, in Japan at least they even do that adopting adults.
