Bullshit. You have just said that there are ways to confirm if someone is using a fake ID, like the fingerprints, so getting new IDs won't help them at all since they would be cross-referenced in the databanks. There's no freaking way they'd escape with that. Besides, one could simply kill and steal the ID o someone else if such cross-references weren't done, and it would be the same, it's not like people keep the same face all their lives. And while they aren't approaching the topic for obvious reasons (CCP), there are millions of people in that situation right in China, though those may be able to provide the parents, or maybe not, if they are dead or without IDs as well. So this explanation for such a crazy control is bullshit propaganda trying to avoid the CCP fury.
