Perhaps you should try some spelling variations:
quan guan » gan guan, quan guo
yan guan » gan guan, yan yuan, yang guang
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
hua ren » hua chen
ren yun » ren yan, chen yun
yun hin » kyun pin, yun chen, yun shik

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: (wan OR lang) ((yan guan) OR (quan guan)) hua ren yun hin ((wong sau) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) ((yan guan) or (quan guan)) hua ren yun hin ((wong sau) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or lang) ((yan guan) or (quan guan)) hua ren yun hin ((wong sau) OR (wong siu)) ;*.
