AN elderly couple featured in a South China Morning Post report highlighting their cramped living conditions have been promised a public housing flat. Housing Department staff have told Chu Leung-lung and his wife, Chu Wong Oi-chun, both 65, they can move to a public flat soon. The Chus are now paying $7,000 a month for their flat in an old North Point tenement building. 'I am happy about what they told me, but I'm not sure how long we will have to wait to get the unit,' said Mrs Chu, who suffers from tuberculosis. Mr Chu was diagnosed as having the debilitating Parkinson's disease two years ago. They rely on their 25-year-old son's $11,000 income to pay the rent and provide the $3,000 they spend each month to meet their daily needs. The rent on the public flat will be between $300 and $750 a month. The Chus' plight was revealed this month after the Hong Kong Society for the Aged published survey findings showing that thousands of elderly people lived in poor environments, despite their serious medical conditions. The society helped the couple apply for public housing.
