You can also become an Oxfam Campaign Partner to help launch campaigns and enhance public awareness of poverty. Teen volunteer: Andy Ning Tin-on, 19, is a first year student at The Hong Kong University of Science and Technology. He joined the Oxfam Club in 2002 when he was a student at Queen Elizabeth School. He is now a volunteer facilitator at the club. 'I have learned many new things from Oxfam. For example, many female workers on the mainland - who work at least 12 hours a day - are being severely exploited. 'Money is deducted from their salaries if they spend too long in the toilet. They work even when they are sick as otherwise they risk being fired. 'But I believe everything in this world can be changed, and the most efficient way to do this is to educate teenagers. 'In 2002, members of the Oxfam Club staged a drama performance. My friend and I also set up a market at my school selling products from a mainland shop which practises fair trade. We sold a variety of products including accessories made by mainland women. We raised about $2,000. 'Recently, we helped Oxfam Club members organise a carnival outside the Kwai Tsing Theatre as part of our public education activities. It was a lot of work, but it is important to let young people know more about poverty-related issues. 'During an Oxfam Club field trip to the Philippines in 2002, we visited a smelly landfill site where people were earning a living by picking up garbage. When a garbage truck arrived, these people - who were mostly children - cheered and rushed towards it to see if they could find anything valuable. 'We need to have empathy. As consumers, we should make our decisions carefully and not do things based merely on our own interests.'
