Hong Kong's problems need to be solved through uniting people and not by chanting slogans, beleaguered Chief Executive Leung Chun-ying said last night. Leung faced another grilling as he attended a third forum, in Kwai Tsing Theatre, before his maiden policy address next month. In his two-minute opening remarks, Leung reiterated the government would start selling a new batch of subsidised housing next week. "I hope that property prices will stabilise soon," he said. The government was also concerned about the elderly and the environment, he said. Audience members raised suggestions on such issues as universal retirement protection, better public health care and education. Several asked Leung how he would mend rifts in society and end his integrity crisis. "Hong Kong needs to be united, in order to solve the problems that have arisen in society. Problems cannot be solved by chanting slogans," Leung said. "I will listen to those who support me, as well as those who oppose me … and I am the chief executive who make district visits most frequently." Leung's comments were met with shouts of "Down, down, Leung Chun-ying" echoing in the theatre throughout the 100-minute forum, while several of his supporters chanted: "Support CY!" The forum was also interrupted for about five minutes when a group of protesters tried to storm into the auditorium. On calls for retirement protection, Secretary for Labour and Welfare Matthew Cheung Kin-chung said the government had set up a task force to look into the matter, with the help of the Central Policy Unit.
