What is this video from

[douggn]

This isn't the original song used in it, I just changed it to an instrumental because I think it sounds better but what is this from. I got the original file from facebook. It kind of looks like something from a music station

I will upload the original and this one if people want it and it hasnt been already. I cant remember what song was used in the original, one of her not so appealing newish songs, that may not be the taste of new comers or non asian music listeners, also why I change it to an instumental to show friends
