The winners of "2007 Happy Boy" television singing contest visited Beijing on Saturday to promote their debut album, 13.

Six of the top 13 were divided into two groups and signed autographs for thousands of fans in two parts of the capital.

The Chen Chusheng-Wei Chen-Wang Yuexin team attracted almost 2,000 enthusiastic supporters.

Some fans had camped outside an event hall overnight to get the best spots in the line so they could see their favourite singers.

The singers scribbled autographs for almost two hours, as security at times struggled to control the crowds.

After the promotion, the two groups of singers rushed to the Tango club, in northeast Beijing, and met more fans.
