Chances are if you speak Mandarin you are about to be disappointed. Kind of how I felt when I heard Se7en singing in Japanese. Now I am not conversational in Japanese but I know enough to know when someones pronunciation totally sucks. I could say the same for this version of “U.” Really if you have a good ear and pay attention to how people talk first thing that will come to your mind is they are singing really slow compared to the Korean version. I will let you decide, enjoy! Oh and Kwfong or Jennifer maybe you can help me with this page and be so kind as to share what the the people are saying, Tudou.com: Super Junior “U” But to be quite honest with you guys I think this song sucks in general. Okay I have more to say about this. First, HanKyung (Han Gen) is the Chinese member of the group. If I was him I would have said we can’t seriously put this out until their Mandarin is better, also his voice sounds no better. Next Hee Chul what the hell was that noise you were making? I just don’t understand these boys are lovable and better actors than they are singers. Honestly I would like to see more drama parodies and Super Junior Shows than hear them sing. Exception being K.R.Y and Super Junior T but Super Junior as a whole is a no in my book.
Chinese Version
Korean Version
If you aren’t sure of who is singing when here is the MV:
Chinese (this is the original video with chinese track so we can see who is singing when)
Korean

the chinese MV is not the original one, isn’t it?coz the lips don’t match the words they say.
anyway, Hee Chul always pretty with ponytails..
