From construction to cardboard: Samsui woman Yip Say Mui, 90, took to collecting cardboard around a market near her Redhill flat after retiring as a construction worker. She can make about $5 a day from two trips to the market -- once in the morning and another time in the evening. While she once stood at 1.58m tall, she is now permanently bent over - from carrying heavy loads all her life. Madam Yip died of throat cancer some months after these pictures were taken.
