Independent candidate Chong Chan-yau and the Democratic Alliance for the Betterment of Hong Kong used Mother's Day yesterday to canvass support. Blind candidate Mr Chong invited his parents to take to the street outside Taikoo Shing MTR station so that he could express his gratitude to them. His father is 91 and mother 81. Mr Chong told of the hard times they went through after he was born with weak eyesight. 'They led me to consult the doctor in Yau Ma Tei. Sometimes they had to walk there from home in Kowloon City to save money,' he said. He played the flute for his parents and Mr Chong's seven-year-old daughter Chong Ching played the violin. His remarks clearly struck a chord as his mother, Chong Chan Yee-hong, wiped away tears several times. Mr Chong's wife, Candice Lam Hou-heung, mother of his two daughters, said her husband was committed to eliminating discrimination against the disabled. Meanwhile, the DAB handed out Mother's Day cards to pedestrians in 10 locations and reminded them not to forget their mothers yesterday. Hong Kong Progressive Alliance chairman Ambrose Lau Hon-chuen let the Liberal Party know he had been busy. Asked at a higher education subsector forum at City University for his feelings on canvassing for votes, Mr Lau said that he had been very busy. 'I've been dashing about all day. Unlike the Liberal Party - they have so many candidates returned uncontested,' he said, gazing at their only Election Committee candidate, Ho Sai-chu. DAB Election Committee candidate Chan Kam-lam was given a cool response after supporting the Election Committee. He mounted his defence at the higher education subsector forum. Mr Chan, an Election Committee incumbent, had just got fully into his stride by saying that the election was 'for elites'. However, he went over the one-minute time limit and was promptly told to return to his seat by forum host Professor Cheng Kai-ming.
