"Bạn thật là cứng đầu."

Translation: You are really opinionated.

[chuaoi]

cứng đầu = hard head(ed) :)

[_The_Undertaker_]

I put that in

[SeSedammua]

"You are really stubborn" wrong?

[qianyanwanyu]

I wrote to a vietnamese friend "bạn cứng đầu quá", she replied
"Don't say that, this is very insulting because this means 3 generations are involved : I'm bad educated by my parents, my grand parents raised bad my parents and so on"
Moreover, rather say "mày cứng đầu", "bạn cứng đầu" is not suitable with the tone

I answered that I heard my mother in law qualifying her son once, she said "A parent can say that to his child"

[GrahamRawlinson]

This is not consistent with the other sentence 'you really are mean'.

Is stubborn a more accurate translation? This word seems to have a negative connotation.
