HONG KONG'S generosity was again proved by the success of Operation Santa Claus '94 which raised $4,234,130 in a month. The money means the Hong Kong Society for the Protection of Children will have two new day centres in Tai Wo and Fanling to ensure that fewer children will be left at home alone. About 200 children will benefit from the centres, according to the chairman of the society's fund-raising committee, Elizabeth Boss. At a ceremony yesterday, Mrs Boss said: 'We are absolutely thrilled with the amount and we are very grateful.' The Financial Secretary Sir Hamish Macleod, the guest of honour at last night's cheque presentation ceremony, said Operation Santa Claus had become a well-known campaign through the effort of its organisers, RTHK Radio 3 - represented by Director of Broadcasting Cheung Man-yee - and the South China Morning Post - represented by Editor-in-Chief David Armstrong. Ms Cheung said that over the years, Operation Santa Claus raised more than $20 million for children's charities. Mr Armstrong took the opportunity to thank the sponsors and community groups saying the campaign was as much about bringing the community together as it was about raising money.
