TEENAGERS who have problems or need someone to talk to can now dial the Youth Hotline (187-2388) on Saturdays and Sundays from 8 pm to 11 pm. Social workers and celebrities will answer the calls and give advice. Youth Hotline , jointly organised by Radio Television Hongkong (RTHK) and 12 counselling associations, is a radio programme aimed at giving teenagers a chance to express their views, doubts and discontent. Calls will be answered from 8 pm to 11 pm on Saturdays and Sundays and the programme will be broadcast live from 10 pm to 11 pm. Showbiz celebrities including Andy Lau, Jacky Chan, Cally Kwong and Dicky Cheung, and prominent figures from different sectors of society will be invited to share their teenage experiences with listeners in the Saturday programme. Current issues such as youth suicides and study pressure will be discussed in the Sunday programme. Twenty Youth Hotline student ambassadors from nine schools and the Hongkong Outstanding Students' Association have also joined forces to help students tackle their problems and to raise concern over teenage suicides. Eva Sum Kwai-ying, one of the ambassadors, said joining the ambassador team and helping fellow students was a meaningful task. ''Youth problems are getting worse and many teenagers consider committing suicide the only way out. As a student ambassador, I can not only help people but also learn how to deal with people,'' the 18-year-old sixth-former from Madam Lau Kam Lung Secondary School of Miu Fat Buddhist Monastery said. She said she would approach lower form students in her school and listen to their problems. Eva has her own way of dealing with difficulties and frustration. ''I talk with my friends and parents. They give me comfort and advice. Also, sports is a good outlet for the anger and frustration.'' Besides giving immediate counselling over the phone, social workers will do follow-up work on some cases. Parents and teachers are welcome to call and express their opinions or share their experiences. The year-long programme will be hosted by Au Lai-ngar, disc jockey Chan King-chong and Outstanding Youth Person, and social worker Siu Chi-kong.
