An American woman who adopted two Chinese girls but only found later that they were sisters is searching for their biological parents in China.

The Changde City Welfare Center in Hunan Province, from where the girls were adopted, said their parents might be from the Pengshui or Qianjiang districts of Chongqing, the Chongqing Economic Times reported yesterday.
"We are sorry for bringing you trouble due to our birth. But we believe you are always concerned about us and we miss you so much," wrote the sisters, now aged 15 and 11, in a letter intended for their biological parents.
The American woman, who was only identified as Bonnie by the newspaper, adopted the elder sister in 1998 and the younger one three years later. She had no idea that they might be related.
The elder sister, Chang Aijie, had undergone surgery to remove a tumor soon after she was born while the younger girl, Chang Xiaofang, was in perfect health, the welfare center said.
Growing up in New Hampshire, the girls became more and more alike until Bonnie eventually suspected they might be sisters and took them for a DNA test.
The test proved her suspicions correct.
