How do abandoned babies find their biological parents when they grow up?

Since it is a station, it must be difficult to find, because they can go everywhere in the southeast, northwest and northwest. Try asking people around you if they remember what happened back then. If no one knows about it, put it in a newspaper or put it online, preferably on TV. In fact, having said that, her parents had already abandoned her, so why should she persist now? It's really hard to find her after such a long time apart. I hope your wishes will come true. The most important thing is to open your mind and if you can't find it, let it be. You must also love your wife. Her life experience is very pitiful, so you love her even more. Finally, I wish you a long life and a happy journey thousands of miles away.
