The family suicide at Tai Yuan House last September haunts residents at the Tsuen Wan Centre. The grief and horror of that day still stark in their memories, neighbours are reluctant to talk about the tragedy, referring to it only as 'that incident'. They say the Chans did not speak Cantonese and seldom spoke to other people. The family was Fujianese and had rented the fourth-floor unit at Tai Yuan House for two years before the gassing. 'We did not know the family well. But it is sad that so many human lives were lost,' Mrs Lee, a fifth-floor resident, said. Her friend, Chen Sze-luen, of the neighbouring block, who has lived on the estate for more than 10 years, said: 'That incident could have been avoided if the family had been more open to neighbours. 'No one likes to talk about that now. We are trying to forget the horrible scene.' District board members have long criticised the Government for the lack of outreach services for new migrants in the district, although the Social Welfare Department points out it has 42 family-welfare centres around the territory. A department spokesman said yesterday: 'We appeal to those who are in need of help to approach us. 'They should not be deterred as we have a wide range of services to offer, but the first thing is they have to let us know their problems.' The Chans' flat was said to have changed hands 20 to 30 per cent below the market price late last year. Caretakers said the new owner had staged a Taoist rite to 'pacify the spirits'. The going rate for a comparable flat in the estate is about $2 million. The unit is rented as quarters for imported workers. Currently it is occupied by a group of Pakistanis who moved in about two months ago. They said yesterday they were not aware of the tragedy.
