Sitting in wheelchairs, limping in special shoes and wearing glasses which stop them from seeing properly, thirty students from the City University of Hong Kong spent a day exploring the world of the handicapped. They were taking part in a one-day course, Journey into Compassion, to help them to understand the problems faced daily by the handicapped. Student affairs officer, Rebecca Chen said it would help create a caring campus community. Ms Chen was inspired by a magazine article on how doctors and hospital in the United States were able to appreciate the psychology of the patients better after they themselves were treated as patients. The idea is that the direct experience of the situation should be the first step to learning rather than study theory.
    Students were sent out in pairs, one handicapped and one observer, to complete a list of everyday tasks. This included borrowing books from a library, exchanging money at a bank and buying a ticket at a railway station. Social work student, Carina Lin, said she could never have imagined how simple task become real challenges for the disabled. “After sharing some of their experiences today, I have become much more aware of the needs and feelings of the handicapped”. Another student said that the experience has taught her to appreciate the ability of the handicapped. Many on the course seemed to have gained an insight into the psychology of the physically handicapped. But there was still much work to be done.
