KWAI Chung squatter Tang Wong Yuk-fa may be relieved her hillside hut escaped the worst of Severe Tropical Storm Becky last week, but she still has a long wait before moving to somewhere more permanent. The Tang family has lived in Kam Shan village for 10 years but will have to wait at least another year before moving into a public unit. The Housing Department plans to clear the hillside structures by the middle of next year, and re-house the 700 squatters into rented units or a temporary housing area in the New Territories. However, Mrs Tang was cautious about the promise. ''The department is used to delaying its projects. When we registered with it about seven years ago, we were told we could be rehoused in five or six years,'' she said. ''The officials just do not understand our difficulties. They choose to overlook our housing problem. Even the Governor did not pay heed to us in his speech last year. ''It is not good enough for him to concentrate only on the sandwich class people,'' added Mrs Tang, mother of a seven-year-old son. She hoped the Government would clear the squatter area before next year's rainy season and re-house the families in urban public flats. People's Council on Squatter Policy chairman Tang Lai-ming shared her views and said squatters living on dangerous slopes should be given priority.
