Answer:
> yew- an.
This first answer is correct.
The 'an' as in "man". And the official Mandarin dialect which sounds exactly the
same is "yuan" where there is an automatic implication of two dots over the 'u'.
However, most modern Chinese people these days have adopted a 'bent' accent
resulting in;
yew- en (sounds like y + when)
They have adopted this accent because it is easier to pronounce and sounds much nicer.
