ok, got answer for one of my question:
"I was adopted from China at the age of six. And it makes me incredible happy to watch these girls. For the people out there who think it is absurd that the Chinese government lied about these girls should not pass judgement so fast. When I were in orphanage, I saw infants die, I saw the disabled children who would never get adopted, and I saw the ones who had got so old that they themselves would eventually be the ones to take care of new abandoned babies. The main aim for the people from the orphanage and the Chinese government is therefore to make sure to make the children as desirable as possible. Because the older they get, the harder it will be for them to get adopted at all. And the fact is that people who adopt do not often apply for twins. The world is not as sweet as candy, but in its all twistedness, amazing things like this happens: the girls found each other and they got wonderful families who do everything to stay connected. These girls are soo lucky! "
