Who is the woman dancing in the video DJ version of Yingshanhong? It seems to be Korean.

That song is called still love you. The girl in orange is just one of his dancers. Her name is Jin Huaying 1982. She was born in JYP at the age of 18. Now she is RAIN's full-time dancer and a newcomer. If she doesn't have a performance task, she will be responsible for guiding newcomers in JYP.
