Lee Hyori has shot three advertisements for Samsung ANYCALL, namely "Anymotion" Lee Hyori ERIC (member of Shinhwa Group)

"Anyclub" Lee Hyori ERIC (member of Shinhwa Group)

"Anystar" Lee Hyori and Lee Jun Ki

These three movies are very famous and quite enjoyable.

The commercial song you mentioned about Lee Hyori and Zhao Mingai was sung by Lee Sang-eun (), and the song is called "When Will We Go". I don’t know who sang the cover of the background music in the MV, but it seems that the background music sounds better.
