Somebody tell me why there are only few asian stars in hollywood and music industry ?

[CuiShiqing]

America is an immigrant country with diverse races people. there are a lot celebrities who are latino, black and white ( no doubt cause majority are). However you can hardly find asian celebrities not mention those kongfu stars. I am wondering how does this happen? If you notice, asian americans worship stars of other races other than asian. Recently famous hip pop group far east movement is constituted of Asian members, I find out there are comments arguing about races on their youtube channel instead of discussing about their talent. Does all the phenomenon reveal that America has serious discrimination against Asian ? somebody give me an explanation plz.
