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, song shin
lang yan » wang yan, wang yang, zhang yan
tuan hua » tuan vu, yuan hui
hong shu » cong shu, tong shui, hong seo
tan hua » wang hua, tan chia, tan puay

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 ((tuan hua) OR (tan hua)) rene sang minh ((hong shu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((tuan hua) or (tan hua)) rene sang minh ((hong shu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((tuan hua) or (tan hua)) rene sang minh ((hong shu) OR (wong shiu)) ;*.
