Mainland shoppers made up more than a tenth of the record-breaking 635,000 visitors who flocked to the four-day electronic gadget fair in Wan Chai, which ended yesterday. But some mainland exhibitors at the Convention and Exhibition Centre still came away unhappy. The Hong Kong Computer and Communications Festival, in its sixth year, reported visitor numbers up 30 per cent up over last year and a total of HK$28 million spent over the four days. Leung Ding-kau, chairman of the Chamber of Hong Kong Computer Industry, which organised the event, said it recorded about 70,000 mainland shoppers, comprising 11 per cent of the total. Last year, about 30,000 mainlanders attended - about 6 per cent of 520,000 visitors. Mr Leung said many mainlanders had come from Guangzhou to buy quality electronics. 'Our target is to develop the fair into one of the most reputable computer expos in China,' he said. However, several exhibitors from the mainland, Taiwan and Macau complained that the location of the stalls they were assigned by the organisers was poor. Michael Tang, a Hong Kong agent for Shenzhen Hasee Computer, said the company did only mediocre business at its booth because of its location. 'We complained to the organiser but there was nothing they could do,' he said. 'We also did not expect to give out as many gifts and accessories as some local exhibitors did, and we could not cut prices like them.' Computer manufacturer Shenzhen Madeway Technology, which ran a booth at the fair for the first time, said they were not told it was a retail gadget fair, and they had expected a business-to-business platform. 'The company was not prepared to sell computers. It was such a wasted opportunity,' a staffer said.
