Art lovers and people with charitable hearts can get a glimpse of the 'invisibles' in Hong Kong from Wednesday at an exhibition organised by the Society for Community Organisation. Despite its glamour and affluence, the city is home to many vulnerable people who lead almost invisible lives, the group's director Ho Hei-wah said. 'Hong Kong is a very rich city but still there are so many people living in the streets. There are so many people with mental illnesses, children struggling with poverty and asylum seekers in the city,' he said. 'While we praise the success of the city as well as its wealthy and famous people, the lives of these people are almost unnoticed.' From Wednesday until March 27, photographs documenting the lives of vulnerable people will be showcased at the Schoeni Art Gallery in Hollywood Road, Central. A charity event will also be held on Wednesday and all donations will go to the society. The exhibition is part of the annual Hong Kong ArtWalk, which celebrates its 10th anniversary this year. On Wednesday from 5pm to midnight, visitors can visit as many as 65 galleries across the city to view an array of artwork as well as enjoy food and wine sponsored by some of the city's leading restaurants. Tickets are priced at HK$430 for adults and HK$100 for tertiary students. 'Hong Kong's art scene is vibrant and strong and ArtWalk remains the biggest one-night art event in town,' ArtWalk organiser John Batten said. It is the second time that funds raised by ArtWalk have gone to the Society for Community Organisation, which runs activities for lowincome groups. Last year, the event drew 2,000 participants and raised HK$477,000. Ho, the society's director, said the exhibition last year on cage houses was a big success. 'Many of the people who joined the event said they had never known that there were lives like that in the city, and that it was beyond their imagination,' he said. Ho said his organisation needed about HK$1.2 million in donations a year to fund its work. '[The ArtWalk] charity event has offered us a lifeline,' he said.
