What exactly is "That Good Good"?  We don't know, but there is plenty of goodness in Luhan's new full MV for his return to the music industry in China.

He dances on the streets with a crowd of y women and talented dancers.  His synchronization with his backup dancers is spot on and he assures you that whatever"good good" he has, it will "make you want to scream."

Does this make you want to scream?
