Perhaps you should try some spelling variations:
yan yuan » yan guan, fang yuan, nan yan
hua rene » hua ren, juan rene
yang jin » yang jie, ying jin, shang jin
yang jun » pang jun, yang judy, yang fan
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
yan ya » nan ya, yang yao
wang » wing, wan, lang

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