Oh Shinhwa.  With your stylish hair, slick dance moves, and rugged good looks, it’s no wonder why you’re still active even today.  This song dropped on June 28, 2001.  This group and this song are credited as one of the starting ripples of the Hallyu.

And before you ask, yes, I did spike my hair like those guys.  It didn’t work.

However, people in Taiwan got a hold of this song and decided to make their own version.  I think the term “copyright infringement” doesn’t translate well into Mandarin.
