The Hong Kong press first reported on a potential child abuse case in 1986. Media reported on a six-year-old child, Kwok Ah-nui, who had allegedly never been outside the family's 200-square-foot Kwai Hing Estate flat. In fact, neighbours reported that the daughter had been taken to the children's playground on rare occasions. It was suspected at the time that the mother, Wong Yuen-siu, was mentally unstable, a claim that was backed by her constant swearing in public.
