The Federation of Trade Unions says regulations that prevent senior citizens living outside Hong Kong from receiving the old age allowance should be abolished. The call came as an 82-year-old man returned from Zhongshan yesterday after moving there more than 10 years ago and is now not eligible for the allowance. The number of days a recipient must live in the city to qualify for the allowance has been cut to 60 from 90. The federation says such a rule is unreasonable and should be abolished.
