Perhaps you should try some spelling variations:
quan glas » quan guan
lang yan » wang yan, wang yang, zhang yan
yan quan » yan guan, yan yuan, yan clan
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, kong sar
yang xi » yang yi, yang jui
rene » rent, gene
sin » sign, sind, skin

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan quan glas rene ((((yang jin) OR (yang xi))) OR (yang di)) ((wong sam) OR (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan quan glas rene ((((yang jin) OR (yang xi))) OR (yang di)) ((wong sam) OR (dong sin)) ;*.
