Here's an article in a Dutch newspaper, brought to you in English courtesy of Google Translate (which explains the choppy read), about a journalist who traveled to China in 2008 & 2009 to trace his adopted daughters' roots and then wrote a book about it called Why China Gave Me Two Daughters:
Wedding-editor Martijn Roessingh adopted two Chinese girls. In 2001 Linde from the northern province of Shaanxi, and in 2004 from Guang Dong Jiang. Now they are nine and six years old, they start asking questions about their background.
The official records of the children tell little and also that information is not always true. Therefore he travels late 2008 and early 2009 to China to see if he could trace their backgrounds. His book "Why China gave me two daughters" on the population policies of China and its quest appears today.
[The photo above illustrated the article, and it says its a poster in China glorifying the One Child Policy.]
If anyone has a link to this story originally in English, I'd appreciate it if you'd give me the link.
