Which of these is the most common Vietnamese family name?

Jo, but how do you say it?

Player judyndisguise, I’ve taught lots of Nguyens, and they all pronounced it “win”.

STEPHEN BODDY, I worked with an attorney years ago by this name and yeah, she pronounced it identically to the English word “when”. No trace of an “n” sound at the beginning.

MY DOCTOR PRONOUCES HER NAME AS " WHEN ". SAME SPELLING AS ABOVE.

Player judyndisguise, new-win
