Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yulu chen » yu chen
wong laid » wong lai, kong land
wong sam » wong sau, wong lai, kong sar
wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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 yan liang yulu chen ((((yang xi) OR (yang judy))) OR (yang yi)) ((wong sam) OR (wong laid)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan liang yulu chen ((((yang xi) or (yang judy))) or (yang yi)) ((wong sam) or (wong laid)) ;*.
