Police believe fewer people will welcome home Olympic gold medallist Lee Lai-shan tonight in Tsim Sha Tsui East than greeted the Governor's arrival four years ago. Lee is expected to draw up to 10,000 people on to the streets, according to officials. Chief Inspector of Kowloon West Traffic, Simon Ip Chung-nin, said police did not expect the tens of thousands who lined Chris Patten's route from the airport on his arrival in 1992. He said Salisbury Road, where San San will greet welcoming crowds, would remain open to traffic, unless 'people start spilling on to the road'. Police and officials last night rehearsed San San's reception at the Hong Kong Cultural Centre, where she is to wave to crowds before boarding a catamaran home to Cheung Chau. Up to 3,000 children from the junior police corps, youth groups and local schools have been invited to join officials in greeting San San in the centre's foyer area. San San is to arrive at the centre with her family in a motorcade of government cars, under police escort. She is expected to leave the airport at 9.15 pm, though much depends on whether her flight gets in on time at 7.30 pm. In Atlanta, San San appeared unaware of the welcome she is expected to get. 'I know there's going to be something when I get back, but I don't know exactly what,' she said. The rest of the Hong Kong team are due to arrive at Kai Tak about one hour after her. Many youngsters believe sports facilities need improving, though the vast majority regularly play some kind of sport, according to a poll. The survey, conducted by the Federation of Youth Groups in the first week of the Olympics, found most youngsters claimed to be budding athletes. But they spurned training programmes and organised clubs. Just over 60 per cent said they played ball games while almost 50 per cent said they went swimming. Eight per cent said they did not take part in any regular sport or recreation. More than 35 per cent of those polled thought the promotion of sports facilities by the Government was insufficient and less than 20 per cent thought facilities were adequate.
