189 of the world's 196 nations will be represented at Expo 2010, either in stand-alone pavilions or within larger pavilions. Singapore, my country also has its own pavilion; a two-story music-box-like structure with an "Urban Symphony" theme.
The theme is inspired by the harmony of unique elements in Singapore: progress and sustainability, urbanization and greenery, tradition and modernity and a cosmopolitan mix of residents of different races living peacefully together.
To commemorate Hong Kong's Participation in Expo 2010 Shanghai China, Hong Kong Post issued a set of 4 beautiful stamps on 27th April 2010.
The bottom left stamp belongs to the 2006 Birds Definitive series.
