迪娜 (dínà)

your name in madarin is 狄娜 or 蒂娜.

i like 狄娜，special and seems have personality.

蒂娜is better~

Your Chinese name is 迪娜，of course the 蒂娜，狄娜 both ok. But I think the 迪娜 is the best , because the 蒂娜，狄娜 are not Chinese tradition name. Every chinese know they are foreignism. So， my advice is 迪娜
