It was a bittersweet day for fans of Super Junior because as their idols begun their first step towards their comeback, it also represented the final notice in that they will only promote with just 10 out of their original 13 members. One of the missing trio who won't be promoting with Super Junior, Hankyung will however still be singing for fans, but it will be through the theme song, The World Watching China for the World Expo 2010, currently ongoing in Shanghai. Hankyung had earlier performed the song on May 2nd at a Chinese Culture event and the full song was released today. Hankyung expressed that Chinese culture is an important pop element of the contemporary world and he will do his best to represent China through this song and promote Chinese culture. http://www.youtube.com/watch?v=9gw_tWiahaY Many thanks to Kingpolo for the tip.
