Deaf people who offer handicrafts in the streets in exchange for donations face prosecution as hawkers without a licence, according to the Urban Services Department. The goods, usually small cloth dolls or tiny decorations, are priced at about $20 or more. Those who pay often see it as a donation to charity rather than a purchase. Assistant director of environmental health, Au Wai-kin, said people seen soliciting sales in the streets would be prosecuted during the raids against hawkers. 'There won't be welfare considerations so long as law enforcement is concerned. It's impossible to tell whether the person is deaf or not from their appearance,' he said. Social workers claim deaf people are being exploited by traders, and that sellers who may not be deaf have harmed the deaf people's image. The Hong Kong Society for the Deaf's research and promotion officer, Clement Ko Hung, said: 'They are getting the products from private traders. Many people do think it's for charity.' Mr Ko said deaf people - about one per cent of the population - did not get enough help to pursue higher education and were confined to a limited range of employment. According to the organisation's social worker Chau Chung-ki, some of his deaf clients complained they were forced to pay for a large amount of products before they could take them to the streets. 'They were told to take their children with them to arouse more sympathy,' said Mr Chau, adding that one member had earned as much as $10,000 a month. 'We can't ask them to give it all up because we can't guarantee they would have similar income from other employment,' he said.
