When it comes to swimming, Diocesan Girls' School (DGS) oozes confidence. The school has won the coveted Division One inter-school swimming title 16 years in a row. In today's finals at Kowloon Park Pool, rivals such as Heep Yunn School (HYS) are eager to spring a surprise and enjoy success that has eluded them for so long. 'I don't think it will be close for the overall honours,' said DGS teacher-in-charge Paulina Hui Lun Yin-kan. 'We will win the Grade B title so easily that the other results won't matter.' Despite the confidence displayed by DGS, team spirit at HYS remains high. 'We have won the Grade A and C titles in recent years and we will push them [DGS] all the way again this time,' said Cheng May-hung, teacher-in-charge of the HYS team. 'The last time we beat them overall was 16 years ago at Victoria Park. I was an HYS student then. We shocked them. They never thought we could beat them. If you are always the champion, victory will never be as sweet unless you have felt the pain of defeat. The HYS students in 2004 have a chance to feel the sense of achievement that we did,' said Cheng. The most decisive races will be the end-of-the-day relays. There could also be plenty of excitement if inter-school records fall. Many races today will feature senior and junior Hong Kong team members. Five schoolgirl swimmers went to the Olympics this year - Yvonne Yip Tsz-wa and Elaine Chan Yu-ning (HYS), Chan Wing-suet and Rosanna Sze Hang-yu (DGS), and Hannah Wilson (Island School). HYS has entered Yvonne and Elaine in the Grade A competition. Yvonne is the Hong Kong 100m and 200m breaststroke record holder, and Elaine owns the 50m freestyle mark. DGS has placed Rosanna, the Hong Kong 50m and 100m butterfly record holder, in Grade B, while Wing-suet, the 200m butterfly queen, will race in Grade A. It will be Wing-suet's final appearance for DGS as she will be leaving earlier than planned to study in Australia. Hannah, who set a new Hong Kong 100m freestyle record at the Athens Olympics, will race in Grade B. 'We realise HYS has put all its best swimmers in Grade A to be more competitive,' said Hui, who has coached the DGS team for 26 years. 'And Grade A will be close. Hannah is in Grade B so that will be challenging for our swimmers, but otherwise there is no one to compete with us in that category. Our Grade C has improved a lot. It might not be strong enough to win. But its time will come soon. I've planted the seeds.' Despite the fiercely competitive nature of the championships, the most important thing is that every team member feels united, said Hui. 'The teams know each other well. It's more about learning how to deal with competition,' she said. 'It is about having the courage to get up there and race, and supporting your teammates no matter what. We always tell them - 'your best is our best'.'
