and CLIFF BUDDLEFOR Chan Tin-sang and his wife Chu Kam-hing, it is a bittersweet victory. Their daughter has won a $6 million nest egg, but cash is a poor exchange for her damaged mind. Mr Chan, a driver earning about $10,000 a month, rejoiced at hearing the staggering payout six years after Pui-ki was knocked down by a Kowloon Motor Bus. 'I always believed it was going to be a victorious case,' Mr Chan, 48, said last night. 'It was human negligence, it was not a natural accident.' The couple plan to build a fund, starting with the $6 million awarded to their only daughter by Mr Justice Cheung, that will support her at least until she turns 60. 'If we are not around, she will be getting some money every month until she is old. This guarantees she will have enough to cover monthly expenses,' Mr Chan said. 'But money cannot change what happened. Pui-ki used to be a very lively young girl. Now she isolates herself from other people.' Pui-ki's life changed forever when, as a 10-year-old, she took two steps on to a Sha Tin road on April 22, 1989, and was hit by a bus. Her parents hovered beside her bed as she lay comatose for 12 days; it was three months before she could leave hospital. Before the accident, she had been a slim, lively child, popular with her classmates and of above-average intelligence. Now she has an IQ of 86, is obese, clumsy, emotionally unstable and changed schools because she could not face the taunts of classmates. Late yesterday, Mr Chan travelled from the family's home at Sun Tsui Estate, Sha Tin, to his daughter's new home at Princess Alexandra boarding school at Kwun Tong to bring her the good news. 'She hasn't asked how much we get. She's indifferent to money,' he said. 'I know it's a ground-breaking case. It will be good news for future victims who face financial difficulties; the amount of damages in Hong Kong has been very low,' Mr Chan said. Pui-ki began studying as a Form Two student at a special education school this month. She dreams of becoming a teacher. However, Mr Justice Cheung was told the most she could hope for was to earn $500 a month in a special workshop for the handicapped. 'We want Pui-ki to find a good job, stand on her own two feet and not have to rely on others,' Mr Chan said. 'The doctors have already told us she doesn't have much chance of working. I hope they're wrong. I hope there are miracles.' He said he and his wife, 47, wanted nothing from the payout: 'We have our health, we have our jobs, we can work.'
