Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
wong shiu » wong siu, cong shu, wong sau
yang jui » yang judy, yang di, yang xi
yang yi » yang di, yang xi
li sang » le sang, li gang, li san
wang » wing, wan, lang
shin » skin, sein, thin

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((yang jui) or (yang yi)) li sang minh ((wong shiu) OR (song shin)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yang jui) OR (yang yi)) li sang minh ((wong shiu) OR (song shin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang jui) or (yang yi)) li sang minh ((wong shiu) OR (song shin)) ;*".
