An American woman searching for her Chinese roots returned yesterday to the staircase of a Shamshuipo building where she was dumped as a newborn baby 38 years ago. Tearful Marv Kreider was shocked by the rundown state of the old urban area and wondered what made her mother leave her there. Ms Kreider, a Los Angeles massage therapist, said: 'Did she just go off me and then walk away? I feel like she knew somebody here.' Ms Kreider was found on the first floor of 192 Fuk Wing Street. A flat there has been empty for years. She was placed in the Po Leung Kuk home for two years until an American couple adopted her and took her to Chicago. Ms Kreider said for years she imagined that she was abandoned in an open place. But she was overcome by tears after seeing the dark, smelly staircase. 'Having lived in your fantasy for so many years, it's kind of hard when reality really slaps you,' she said. Ms Kreider has been writing to the Po Leung Kuk for information since 1990, but has found few details on her case, which dates back to July 1958. A library search also failed to throw up any clues. Ms Kreider said she grew up with the couple's two natural children, but was anxious to know her own origins. An elderly man in the building said a couple who had lived in the vacant flat had emigrated to the US in the early 1970s. He said they had had a maid who gave birth to an illegitimate child. Another man said a woman in her 20s had been to the building two years ago looking for an abandoned baby. Ms Kreider is considering advertising for information to help her search.
