AT THE TENDER age of 14, Luk Chun-wa has experienced a 'sex change' - he became a female nurse in an online game because 'it helps to be a girl'. But when the PLK Centenary Li Shiu Chung Memorial School student and his friend Kong Chun-hin, 13, actually met a male nurse at Queen Mary's Hospital, both were very impressed. 'This is definitely a breakthrough,' said Chun-hin of Queen's College. 'I used to think of all nurses as being like Florence Nightingale,' he said. Organised by the Equal Opportunities Commission (EOC), Career Challenge is a programme being undertaken by about 100 Form Two and Three students. These were divided into 11 groups which, in the last two months, have spent half a day with career 'mentors', observing them at work and sharing experiences. The mentors included a film director, artists, legislators, a hospital worker, an academic and a public affairs consultant. The EOC devised the programme after a survey in April indicated strong occupational stereotyping among students. At Queen Mary's Hospital, eight students met Danny Law Wai-keung, operations manager at the accident and emergency department. After a tour of the department, the students and Mr Law had a chat. 'I loved medicine as a child,' he said. 'I began reading about it in Primary Four or Five,' Mr Law recalled. 'So when in Form Six a friend suggested we apply to nursing school together, I said OK.' There was little opposition from his family although nursing was, and remains, a predominantly female job - in Mr Law's 20-year career, the ratio of females to males has remained at roughly 10 to 1. In response to a question about male nurses being labelled careless, Mr Law said the criticism was more often directed at individuals rather than a gender group. 'There are individual variations,' he said. 'But this is such a tough job that those who aren't devoted won't go into it.' Audrey Eu Yuet-mee, a barrister and legislator, told nine boys and girls that she went to law school in 1972. 'There is no direct relation between gender and ability to work in a certain field,' she said. 'But at that time, girls had limited education opportunities because of the larger families and lack of financial resources.' Ms Eu admitted that some people did see female barristers in a different light. She has suffered little discrimination, but she added that people have different interpretations of the same thing. 'When I first started, some said that I could win a case easily - all it took was a smile at the judge. Some took this as a discriminating remark, but I thought it would be pretty good if I could win a case with just a smile!'
