CHEUNG Chi-keung wants Rosanna Wong Yick-ming to visit him and his six relatives in their cramped Ho Man Tin flat and experience their problems for herself. ''It's no use sitting in an office and making decisions without consulting tenants,'' said Mr Cheung, who lives in Oi Man Estate. ''It's vital for us for the chairman to come and meet us, listen to our views and experience our hardships, because each family has different housing problems.'' Mr Cheung, 39, has lived in his 500-square-foot flat for almost 19 years. He shares the flat with eight relatives. His two younger sisters recently moved out because it was too crowded. There is a living room and three bedrooms - one for his other three younger sisters and mother, one for Mr Cheung and his elder brother, and the third for his younger brother. There is barely any space to move in the bedrooms. ''It was okay when we moved in 19 years ago, because we were young, Mr Cheung said. ''But it got crowded as we grew up. It's better now because my two sisters moved out last month.'' Although the overcrowding has been eased, Mr Cheung said the rent was still a problem. His family is one of the 61,500 households which has been hit by the double-rent policy. They moved into the flat in 1974, when he claimed his rent was among the highest on public housing estates at about $550 a month, even though his family's combined income was only about $1,500 a month. ''We were required to pay double rent in 1991 of $3,271 a month because my family's monthly income was over the limit. That's not fair,'' he said. The double-rent policy has recently been changed. Tenants who have lived in public flats for more than 10 years are now required to pay double the normal rent if their monthly income is more than treble the $15,300 limit allowed for public housing. Tenants with income of twice the limit pay 50 per cent more. Mr Cheung hopes he will not be required to pay double rent under the revised policy. At present, his family earns more than $30,000 a month. A former ivory worker, he has been unemployed for eight months. ''The double-rent policy is the housing issue I am most concerned about,'' he said. ''I'll be glad if the chairman was to come here and really listen to me and do something for us. ''I think she should, like the Governor, visit public housing estates and temporary housing estates, and talk to us. It's no use sitting in her office and making decisions without consulting tenants.'' But he was worried Ms Wong would be unable to reflect tenants' views because she was appointed by the Government. He also doubted her knowledge of housing problems. ''At the moment, it is difficult to say whether Ms Wong will be a good chairman of the Housing Authority because she has not started her work. But I hope she will look into the present housing policies and discuss the problems with us,'' said Mr Cheung.
