Perhaps you should try some spelling variations:
yang yao » yang yang, wang yan, yang fan
hua rene » hua ren, juan rene
yang jin » yang jie, yang jun, ying jin
jin wong » jin song, john wong, jin ying
wong sau » wong sam, wong siu, wong shiu
yang yi » yang di, yang xi, yang jui
yan ya » nan ya, yan yuan

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 OR wan) ((yan ya) OR (((yang yao) OR (yang yi)))) hua rene yang jin wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(lang or wan) ((yan ya) or (((yang yao) OR (yang yi)))) hua rene yang jin wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (lang or wan) ((yan ya) or (((yang yao) OR (yang yi)))) hua rene yang jin wong sau ;*.
