Perhaps you should try some spelling variations:
liang yung » liang ying, liang sun, liang liying
yan liang » yang liang, wang liang, you liang
yung chen » yun chen, yu chen, yulu chen
yang jui » yang xi, yang yi
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
wang » wing, wan, lang

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: wang yan liang yung chen ((((yang judy) OR (yang di))) OR (yang jui)) ((wong sam) OR (wong sau)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan liang yung chen ((((yang judy) or (yang di))) or (yang jui)) ((wong sam) or (wong sau)) ;*.
