TWO elderly Tai O villagers, whose homes are to be torn down in a redevelopment project, will be rehoused in the district where they have spent half their lives after a desperate plea to the Housing Department. Wong Wai and Chan Kau have been living in their wooden huts in Yim Tim Pok village, Tai O, for more than 30 years, and depend on their neighbours for even the most basic help. The Housing Department has offered them an 344 square foot flat in Lung Tin Estate, Tai O, which was originally intended for a family of seven. The department's assistant housing manager, Yip Pak-yuen, said the offer had been made because of the men's special circumstances. The two men, who survive on public assistance and are in poor health, had made a plea to be allowed to live their last days in their hometown. Wong Wai, 67, who suffers from asthma and depends on his neighbours and social workers to deliver food and buy necessities, said: ''I am very happy. I have finally found a shelter to enjoy the rest of my life in my hometown.'' Social worker Chan Sui-ming, who has looked after the men for many years, said it was incredible that the Government gave them a flat in the same district. ''They do not have to worry about the accommodation problem and can enjoy the rest of their lives,'' said Mr Chan.
