Should one write “妳好" when addressing a female? With traditional Chinese characters it is correct and proper to address a female as “妳”.

If I have a simple question, I think it's clear I should use the female form.


  妳最近好嗎？


But to say "hello", “你好” feels more like a set phrase.

So my question is simple,

Should I write 


  妳好


when addressing a female?

Or just use the gender-neutral


  你好
Yes you can definitely use “妳好“ when addressing female. 

However notice that in Chinese there isn't a strict usage defined to differentiate addressing male and female. If you use "你" instead, the reader will not (and probably should not) assume a male is addressed in the context.

In other word, "你好" is perfectly fine to address female without any grammatical concern.
