Part-time cab driver Bobby Lui Hon-kin insists he is not a fighter, but he is being modest. Mr Lui has, in fact, been fighting for the past 30 years - against injustices big and small. From asking for a bigger unit at Lei Cheng Uk public housing estate due to his need for wheelchair access to complaining about broadband cable installation and poor TV reception, the 43-year-old has not backed down from a fight. Perhaps his most significant battle was to badger the MTR into providing better facilities for the handicapped. 'When the MTR first started operations in the early '80s, there were hardly any special arrangements made to help the physically disabled like myself. It was a real hassle for us to get on the escalator to get to the platform,' he said. 'We began writing complaint letters to them, along with many other charity organisations. Eventually, they gave in and designed special wheel access facilities.' But Mr Lui doesn't just fight big battles. When he signed up to a broadband service, he noticed how his connection would slow down every now and then. He complained to the firm, Hong Kong Broadband, but was told that nothing could be done. His complaints that the poor connection violated the contract he signed appeared to fall on deaf ears. But Mr Lui persisted, making up to 20 telephone calls to both the company's officials and the Telecommunications Authority. His persistence paid off and the firm fixed his line. Another small battle was against i-Cable. He complained that the firm's cables running through his building were interfering with his TV reception. After going to the authorities, i-Cable fixed the problem. 'I don't want people to see me as a saviour of society or anybody. It's only that I believe in the theory that if you don't speak out, you'll never get justice,' said Mr Lui. Born into a family with eight children, Mr Lui suffered from polio as a child and has had to use crutches all his life. He joined the Hong Kong Physically Handicapped and Able-bodied Association at the age of 13. 'Though I've never held any official position, I'm one of the veterans after being actively involved in the organisation for so many years,' he said. 'At first I wanted to join something just to broaden my social network, but after a while, I began to realise it was a good way to help fight for the rights of disabled people. 'But in the end, I think I'm just being selfish because I'm also one of those who'll benefit from the outcome.' Although he believes disabled people should enjoy certain privileges, Mr Lui says he doesn't see himself as unlucky. He refuses to rely on charity, and has had a wide range of jobs, from electronics technician to freelance magazine typist and editor, to taxi driver. 'I don't see myself as being particularly adaptable. I always believe that to survive, you must continue to do things that can help you keep up with the world.'
