I think this is right so. I have found the Vietnamese text, in this page:
(Danh ngôn của William Shakespeare)
Tồn tại, hay không tồn tại: đó là câu hỏi.
To be, or not to be: that is the question.
Still the original in English is a little different.
To be, or not to be, I there's the point, (from the First Quarto - 1603)
But the Second Quarto (1604) presented this that we know now:
To be, or not to be, that is the question, (https://en.wikipedia.org/wiki/To_be,_or_not_to_be)
