You may like to find out why Sergeant Fu Keung San-ling of the Police Public Relations Branch (PPRB) is called 'Do-Re-Me' by her colleagues. It is because the last three digits of her police identification number are '1, 2, 3', which in Cantonese are sometimes substitutes for musical notes. Mrs Fu retired from the force last month after 36 years of service, 24 of which she spent in the Junior Police Call (JPC) Youth Liaison Section of the public relations branch. As the longest serving officer in the branch, she witnessed the rapid growth of the JPC scheme into one of the largest youth organisations in the world. 'There have been many changes in the JPC since it began in 1974. 'Today it is much more diversified in its activities and membership, which includes over 700,000 young people,' Mrs Fu said. At a farewell dinner, 'Do-Re- Me' was presented with a picture entitled, Mother of the JPC, in recognition of her contribution to the scheme. Her loyalty and dedication earned her a Colonial Police Medal last year and a commendation by the Commissioner of Police in 1976. 'I liked the job very much because working with youngsters made me feel young and optimistic,' she said. All the best 'Do-Re-Me'!
