I really love this song!! It's from taiwanese drama series called : "斗牛, 要不要". 斗牛 means it's a kind of way to play baskeball where it's not like normal playing with rules. It's like a street kind of playing. The story begin with 斗牛!
Another reason I like this song is because is from my favourite idol- S.H.E!! They sing well. They really not like those hardcore singer with really great voice, but their harmony is nicest of what i heard. Another is their "senior" called 动力火车!!
