Enter the exhibition halls of the Hong Kong Central Library this month and the first thing that grabs your attention is a large photograph of a young girl lying on the floor, her father looking down at her. Wang Kaijai, the girl in the photo, is only four years old and, already, she has Aids. This touching image is just one of 250 photographs that make up Positive Lives, an exhibition showing how ordinary people around the world are living with HIV and Aids. Positive Lives has been touring the world for more than 10 years and is being shown for the first time in Hong Kong. It was launched here on May 1 and actors Shawn Yue Man-lok, Niki Chow Lai-ki, Julian Cheung Chi-lam and Patricia Liu Chuk-ki were there to support the event. 'I hope all my fans will come to support this exhibition,' said Yue. 'It's not only a chance for young people to learn more about Aids, but it also makes you realise that positive thinking is the only way to overcome the difficulties you face.' Chow said that when she was younger it was taboo to talk about Aids, but with society opening up it had become easier for today's youth to learn about it. This is one of the reasons she is encouraging young people to visit the exhibition. Cheung agreed. 'Young people are our future; they need to learn the realities of the world today.' Besides opening the exhibition, the celebrities also handed out prizes to the winners of a poster competition organised the Hong Kong Aids Foundation. The winner was 15-year-old Mok Suet-fan from Po Kok School. The runner-up was 10-year-old Lau Hei Tung from Kowloon True Light Primary School. The foundation has been giving talks about HIV and Aids in schools for years and became involved with the Positive Lives project two years ago. Since then they have visited more than 200 schools, showing a selection of pictures from the exhibition. Vivian Leung, one of the foundation's education officers, said students often thought that Aids had nothing to do with them. But, she said, the exhibition could help change this. She said one of the pictures that students react to the most shows a 17-year-old Cambodian boy called Lundi. In the photograph he stands in a field holding a fishing net and looks just like any other boy. It's only when you read the caption that you discover both his parents have died from Aids. He now lives alone and supports himself by fishing from midnight until 6am. He then goes straight to school. Ms Leung said this picture made students realise how lucky they are and how Aids could affect them one day. This sentiment is echoed by Kevin Ryan, the project director of Positive Lives, who is himself HIV-positive. 'HIV doesn't care if you are young or old, straight or gay, European or Chinese, Christian or Muslim, black or white,' he said at the launch. 'Today, 10,000 people will be infected with HIV, tomorrow the same will happen, and the next day. It's a worldwide problem so we all have to care about it.' Positive Lives runs from 9am to 8pm until May 24 at the Hong Kong Central Library in Causeway Bay. Admission is free. For enquiries call 2560 8528.
