Looking for people who would have known my sister before her adoption

My sister, Reese, was born October 8, 2004, in Taiyuan, Shanxi Province, China. She was then known as Dang Kai Jin. I am looking for anyone who may have volunteered through the China Care Foundation in their Taiyuan or Beijing Children's Homes or visited these homes. She has been in both as one point or another, and was also in foster care. I am looking for these people to gain more information, and possibly pictures, of Reese before we adopted her. She has a port-wine stain birthmark on the right side of her face, as well as on her lower extremities. She also has glaucoma in her right eye. If you think you may have met/seen her, please PM me.
