Wong Mui Foon-sai, 69, last night spoke of her hopes for her son's speedy return. She said she could clearly recall the moment he said good-bye almost five years ago. 'He said he would be back in five days' time,' she said. Mrs Wong has been living alone since her son left and has been unable to afford the fare to visit him in his Manila jail cell. She said she could not go to the airport to greet him because of poor health. A 1991 calendar hanging on the wall of Mrs Wong's 50-square-foot room in an old building in Shamshuipo acted as a constant reminder that her son had been taken away from her. It was shortly after he brought the calendar as a gift for his mother that he went on the trip to the Philippines, only to be arrested on his arrival and sentenced to life imprisonment. Mrs Wong, who lives on $2,000 a month public assistance, is hoping to treat her son, 49, to a dinner when he comes back. 'I have also cleaned his bed and taken out some of his clothes which have been packed,' she said. 'I had thought he would never come back.' Mrs Wong is also prepared to greet her son with the good news that they might soon be allowed to move to a public housing flat in Wong Tai Sin. 'We were asked to go to have a look at the flat on the 22nd of this month,' she said. 'We can go together. I am very happy.' Mrs Wong said she had not told her son about the news because she was illiterate and did not want to trouble others to help her write letters to him. 'Once I heard that he thought I was dead,' she said. 'I immediately took a picture and asked Mr Au's brother to take it to him. 'No friends or relatives have visited him over the past five years. I cannot go because of my poor health.' Mr Au's mother, Au Yeung Kit, 71, yesterday said she would prepare her son a bath with pomelo leaves, which are believed to be able to help wash away bad luck.
