This is an interesting article that discusses how one Chinese adoptee, Jenna Cook, who was born and abandoned in China and subsequently adopted by an American couple, has been trying to find her birth parents in China using media notices and DNA. This story is also relevant for many Australians who were adopted from other countries and I think we will be seeing more use of DNA testing for these kinds of adoption cases.
Jenna Cook put up 800 posters in Wuhan, China, in her efforts to find her birth family. Behind her, a passerby is reading the poster.
