Young people in Hong Kong do not know much about the Pearl River Delta (PRD), but they are keen to learn. The Hong Kong Federation of Youth Groups interviewed 544 people, aged between 18 and 39, for their opinions on the latest policy address, in which Chief Executive Tung Chee-hwa talked about the development of the PRD. More than 55 per cent of the respondents wanted to learn more about the region, while 46.7 per cent wanted to make a study trip there. James Mok Hon-fai, the federation's research and leadership supervisor, said some respondents had little knowledge of the PRD and its development. 'When I asked some students whether they had been to the Region, they said 'no'. But when I asked them if they had been to Shenzhen or Guangzhou, many said 'yes',' Mr Mok said. He added that many students were not even familiar with the term 'Pearl River Delta'. In view of this, Mr Mok said it was important to organise study trips to the region. Among the four 'pillar industries' - tourism, logistics, creative and finance, identified by Mr Tung as the keys to Hong Kong's future prosperity - tourism was the most popular. More than 24 per cent of the respondents said they would like to work in the field. Mr Mok said tourism was more popular among young people because many believed the industry did not require professional qualifications.
