Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
yang min » yang mind, tang min, yang lin
yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yan yaa » yang yao, nana yaa, yan yuan
yaa hua » ya hua
hua ren » hua chen
hong yu » wong yue

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 yaa hua ren ((yang min) OR (yang jin)) ((((wong sau) OR (wong sam))) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yaa hua ren ((yang min) or (yang jin)) ((((wong sau) OR (wong sam))) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yaa hua ren ((yang min) or (yang jin)) ((((wong sau) OR (wong sam))) or (hong yu)) ;*.
