I get all of that. What puzzles me is "If an adoption isn't approved by the end of the 4 years, the kid returns to the bio family, either to the parents or to some other members of the extended family." Maybe I'm misreading, but it sounds like if someone doesn't take the kids permanently in a certain length of time, they go back to the bio family regardless of fitness. And I don't understand why, if the bio family was fit in the first place, the kids were still up for adoption, and what happens at the four year mark that didn't happen before then. I mean, I'm assuming they don't just say, "Well, we tried to find them a safe permanent home, but that didn't work out, so I guess these people can take them."
