Rubber duck stars at Cheung Chau Bun Festival

That Rubber Duck is at it again - after stealing the hearts of Hongkongers since sailing into the harbour, it is stealing the show at Cheung Chau's Bun Festival.

The 16.5-metre-tall artwork has got everyone duck crazy.

And while the traditional buns stamped with the iconic "peace" logo continued to be a big hit, rubber ducks could be seen in the parade and on various products on sale.

One stand was selling T-shirts featuring a rubber duck with a swimming cap stamped with the peace sign.

"We designed this because of the rubber duck fad and crossed it with the festival. Both give the message of peace and joy," said designer Wong Wai-yin, 25, who is running the stall with his brother and sister.

Last year, he said they sold 90 per cent of their stock during the three-day festival.

This year they have about 600 T-shirts in different designs, at HK$89 each, plus other souvenirs, like a postcard that reads "Keep calm and climb on".
