Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song ming
wong shiu » wong siu, cong shu, song shin
song min » song ming, gong min, jong min
wong sau » wong sam, wong siu, wong lai
hong hai » shang hai, zhong tai, dang hai
yang xi » yang di, yang yi, yang jui
hua ren » hua chen
ta hua » tan hua, ya hua, tuan hua
xi ta » x ta, yi ta

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: yang xi ta hua ren ((sang minh) OR (song min)) ((((wong sau) or (wong shiu))) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang xi ta hua ren ((sang minh) OR (song min)) ((((wong sau) OR (wong shiu))) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang xi ta hua ren ((sang minh) OR (song min)) ((((wong sau) or (wong shiu))) or (hong hai)) ;*".
