A Chinese boy and a Polish boy won the art competition for the Polish National Pavilion Day yesterday.

Polish Minister of Culture and National Heritage Bogdan Zdrojewski awards the two boys their winner’s certificate.

The art competition was organized by Poland's Pomeranian Voivodeship, and it collected applicants' artworks for future cities in the voivodeship and Shanghai, a sister city.

Up to 635 students aged from 8 to 12 from Pomeranian Voivodeship and 235 counterparts from Shanghai joined the competition.

The prizes for each winner include a laptop and a trip to the other city. The Polish winner had visited the Expo site with his parents. The Shanghai winner will visit the voivodeship in September.

The Shanghai winner's painting was the future city of Dujiangyan, a city badly hit by the 2008 Sichuan Earthquake, and he said that he was inspired by Shanghai's support for the rebuilding of the city in southwest China.
