Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
rene sang » lee sang
wong shiu » wong siu, cong shu, wong sau
lang yan » wang yan, wang yang, zhang yan
yan hua » ya hua, wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia
shin » skin, sein, thin

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

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((yan hua) OR (tan hua)) rene sang minh ((wong shiu) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yan hua) or (tan hua)) rene sang minh ((wong shiu) OR (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yan hua) or (tan hua)) rene sang minh ((wong shiu) OR (song shin)) ;*.
