Standard Chinese rendering of 'Dana' (also Dannah / Danna) —
丹 (dān) renders 'da-' and
娜 (nà) is the universal feminine-name closer in Chinese transliterations:
安娜 Anna,
戴安娜 Diana,
朱莉娅 Julia. English-speaking 'Dana' is sometimes male in the US (e.g. UFC president Dana White), but the
娜 ending in Chinese marks it unambiguously female; for the male Dana, transliterators may use
达纳 (Dánà) instead.
