Aged between 13 and 20, they made all of the decisions relating to the project themselves, including where to locate their stalls, strategies to bid for a desirable place, what to sell, and how much to charge.

The centres provide the budding entrepreneurs with support, such as the transportation of goods to the night markets.

Each team will make a short documentary about their experience, which will then be shown at a forum being run by the organisers for association members in March.

The programme was started last year to give the association's young members a taste of what it is like to run a business, says Cheng Shuk-yi, a social worker at the association's Kwai Shing centre.

The youngest team, Start-up Kids, consists of 11 Form Three and Form Four students with experience from last year selling pyjamas.

Using that small profit, they sold sweets to raise more money to support this year's project.

Together with their own pocket money, the team raised about $4,400.

This year, they will be selling pyjamas and accessories in the Kwai Shing district.

'We hope to attract more customers by selling a wider range of goods,' says Wong Ko-hung, 14.

The Yeung Wah Wah team suffered a small loss last year. Now the team of 10 are more aware of who makes up their market.

'There are children and older people in Cheung Sha Wan, but not many teenagers,' says team member Jack Wong Ho-kei, 19. '[And older people] like things that don't cost too much.'

The other teams - A Happy Family, Serving The People and Con.U - are new to the night markets.

They hope to attract customers with products that they designed and made themselves.

Although the results are yet to be seen, the youngsters have already shown an improvement in the way they handle money, Ms Cheng says. 'They have always been careful with money, but now they can manage [it] more wisely.

'Having made more important decisions, they have also matured,' she adds.
