Perhaps you should try some spelling variations:
yan yuan » yan guan, fang yuan, nan yan
yang jie » yang jin, yang di, yang xi
yang jui » yang di, yang xi, yang yi
wong sam » wong sau, wong lai, kong sar
yan yan » nan yan, yang yang, wang yan
hua ren » hua chen
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 yan) OR (yan yuan)) hua ren ((((yang judy) OR (yang jie))) OR (yang jui)) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) OR (yan yuan)) hua ren ((((yang judy) or (yang jie))) or (yang jui)) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yan) OR (yan yuan)) hua ren ((((yang judy) or (yang jie))) or (yang jui)) wong sam ;*.
