Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang yao » yang yang, wang yan, yang fan
hua rene » hua ren, juan rene
yang min » yang mind, yang jin, tang min
wong yue » wang yue, hong yu
yang ka » yang fan
yang yi » yang di, yang xi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang ka) or (((yang yao) OR (yang yi)))) hua rene ((yang min) or (sang minh)) wong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang ka) OR (((yang yao) OR (yang yi)))) hua rene ((yang min) OR (sang minh)) wong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang ka) or (((yang yao) OR (yang yi)))) hua rene ((yang min) or (sang minh)) wong yue ;*".
