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

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 yao) or (((yang yi) OR (yang jui)))) hua rene ((yang li) or (sang minh)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang yao) OR (((yang yi) OR (yang jui)))) hua rene ((yang li) OR (sang minh)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang yao) or (((yang yi) OR (yang jui)))) hua rene ((yang li) or (sang minh)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yang yao) or (((yang yi) OR (yang jui)))) hua rene ((yang li) or (sang minh)) hong yu ;*.
