K-pop & C-pop suggestions

[Genki+]

I want to listen to more Asian music but I don't know where to start. I am especially interested in Korean pop & Chinese pop music. I never listened to any C-pop artists & the only K-pop artist I listen to is BoA. So, I need suggestions!! I prefer female vocalists who are in their teens-early 30's for some reason. & please tell me a bit about them or post a video or a fansite or something.

thank you
