Perhaps you should try some spelling variations:
guan rene » juan rene, glas rene
lang nan » jiang nan, lang lang, dong nan
yan guan » gan guan, yan yuan, yang guang
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang yi
wong sam » wong sau, wong lai, kong sar
nan yan » nan ya, wang yan, qian yan
yang xi » yang di, yang yi
sin » sign, sind, skin

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 nan yan guan rene ((((yang jin) OR (yang xi))) OR (yang jui)) ((wong sam) OR (dong sin)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang nan yan guan rene ((((yang jin) or (yang xi))) or (yang jui)) ((wong sam) or (dong sin)) ;*.
