First of all, the question "Why do foreigners only adopt girls from other countries" is too absolute. The world is so big and there are so many countries, there will inevitably be countries that adopt their own girls.
Secondly, the media prefer to pay attention to the adoption of children from other countries by their own people to show their gratitude. Of course, for adoptive families, it is indeed out of goodwill, but it has been infinitely expanded.
Third, not all adoptive families are happy, so foreign media also have the problem of burying the truth.
Fourth, this country has different populations. For a populous country, how can we care so much about outsiders when our own people have never taken care of them?
Fifth, why can't we see that among the so-called girls adopted by foreigners, there is the most controversial refugee problem at present, such as the world police with large territory, small population, rich resources and developed.
To sum up, except for Denmark, Switzerland and other countries recognized as peaceful countries in the world at present, other countries do not exclude local media and use the goodwill of some people to promote the world!
