Perhaps you should try some spelling variations:
quan guan » gan guan, quan guo, yan guan
guan rene » juan rene, glas rene
lang yan » wang yan, wang yang, zhang yan
yan quan » yan guan, yan yuan, yan clan
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, wong lai, kong sar
kong siu » kong eiu, wong siu, dong sin
yang yi » yang di, yang xi

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 yan quan guan rene ((((yang jin) OR (yang yi))) OR (yang jui)) ((wong sam) OR (kong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan quan guan rene ((((yang jin) or (yang yi))) or (yang jui)) ((wong sam) or (kong siu)) ;*.
