Chinese languages

Could somebody please translate my girlfriends name into symbols... she is from Hong Kong and I want to suprise her by being able to write her name in Chinese

Anyway her name is:
Wong Hoi Wan (Wong being her family name obviously )

Many Thanks!

“Wong ” means 王
王 is her family name

"hoi " I don't know what does it mean, because "hoi" is not chinese pinyin

I guess it means 海 or 红

"wan" means 婉

So your girlfriends name in chinese should be 王海婉 or 王红婉

Cantonese sounds different from Mandarin.
So 'Wong Hoi Wan' could be 王海云
