The wife of housing chief Dominic Wong Shing-wah yesterday came to his defence against recent criticism of his work. It was the second time Cecilia Wong Kwai-fun had publicly supported her husband. In 1995, when he was in charge of education, she wrote to Ming Pao, saying accusations that he had mishandled the promotion of some teaching staff were unfair. In yesterday's letter sent to the media, she said claims he was not doing enough to solve housing problems were untrue. Mrs Wong said a 12-hour working day was a luxury for her husband. 'He cannot go to sleep until 3 am the night before going to Legco to answer questions raised by honourable members . . . 'He cannot go home and have lunch until 4 pm on Saturdays,' she said. 'He is a responsible, honest and reliable civil servant who has devoted much time and effort to his job. 'However, he gets nothing in return but criticism, sneering, misunderstanding and even intimidation,' the letter said. An anonymous letter from a 'high-income-tax payer' angry with housing policy, was sent to a newspaper with a packet of poison on Friday. Married for 24 years, Mrs Wong, a housewife who does regular voluntary work, said she was simply expressing her feelings. 'I am not begging for sympathy. I just want the public to know more about the life of a civil servant, which is not as comfortable as people imagine.' She said her family understood the hardships people had to undergo to buy a flat. Lo Chau, chairman of the Hong Kong People's Council on Public Housing Policy, said Mrs Wong's act of support was understandable. 'But hard work does not mean everything. What is important is whether he can solve the problem.' Two weeks ago, a hoax bomb in a box painted with slogans threatening Tung Chee-hwa and Mr Wong was found outside Legco.
