So, I'll confess to not be an expert on East Asian studies, but the Iron Fist wiki says Colleen Wing is the daughter of two allegedly Japanese parents, is a student of Kenjutsu, and has a lot of other Japanese overtones.
But Wing doesn't sound to me (admittedly a Westerner) to be very Japanese, sounds more Chinese to me. And in her intro scene in the Netflix series, she is shown to know some Mandarin. But I couldn't find anything in her backstory online to indicate either of her parents were Chinese or spoke Mandarin.
What am I missing?
