It was supposed to be a mutual exchange on conservation policy. Instead it became a venue for indigenous villagers to vent their rage against environmental officials. The outpouring of their bitterness dominated the two-hour meeting. Brian Kan Ping-chee, the outspoken Heung Yee Kuk member who was ousted from the Sheung Shui rural committee chairmanship in an election two years ago, fired the first shot by stopping officials from outlining their conservation policy. The former champion horse trainer went as far as to personally challenge Secretary for Environment, Transport and Works Sarah Liao Sau-tung. 'The Long Valley is all man-made wetland ... I know that as I was born there in 1937. Have you ever laboured in the fields?' he asked. 'You might be more educated than me but I've got more community experience than you.' Mr Kan said the government liked to bully indigenous villagers while turning a blind eye to pollution caused by developers. The meeting turned even more emotional when Cheung Tin-fuk, head of the Sha Lo Tung village, rose to tell his plight. 'I really want to slap you on the face, but I can't as you are quite beautiful,' he said. Mr Cheung said he had been deprived of a good life because he could not develop his land. The environment officials - including Dr Liao, permanent secretary Keith Kwok Ka-keung, his deputy and assistants - sat stone-faced throughout the fierce criticism. They were given just 15 minutes to respond at the end of the meeting. Dr Liao was then escorted away by kuk leaders while dozens of angry villagers chanted slogans. She was driven away without answering reporters' questions.
