Chinanews, Beijing, July 20 - The first gene library for looking for missing family members has been completed in Beijing, which will help orphans to find their root.It is estimated that currently there are 500 thousand people in China looking for family members with whom they have lost touch for long.Lu Shunfang, a warm-hearted woman from Guanlin of Yixing County, Jiangsu Province, initiated the building of the gene library. Lu has lost track of her sister for year, and she has met many people with similar experiences in her journey of looking for her sister.In 2000, Lu organized several meetings to help these people, with more than 1,000 people attending each.Lu found that such meetings were not efficient enough for people to identify their family members, for they had to rely on their dim memories of appearance, voice, birthmarks, etc."Many people found wrong family members at the meeting, thus I thougt we should build a gene library, which would be more precise and more efficient," said Lu.Lu told her ideas to the Center of Forensic Sciences, and jointly, the gene library was set up.
