WEi remixed a Korean classic on 'Immortal Song'.

On the September 18th 'World in Taekwondo' special, WEi created their own medley of the Korean folk song "Arirang". The group incorporated traditional fashion and dance elements as well as taekwondo moves into their performance.

However, it was musical actress Shin Young Sook who took the final win.
