Perhaps you should try some spelling variations:
liang kang » liang dan, liang tan, liang ying
yan liang » yang liang, wang liang, you liang
kang chen » chang chen, jane chen, kang han
yang jie » yang jin, yang jui, yang yi
wong siu » wong shiu, kong siu, wong sau
wong sam » wong sau, wong lai, kong sar
wan yan » wang yan, nan yan, wai yan
yang xi » yang yi, 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 kang chen ((((yang xi) OR (yang di))) OR (yang jie)) ((wong siu) OR (wong sam)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan liang kang chen ((((yang xi) or (yang di))) or (yang jie)) ((wong siu) or (wong sam)) ;*.
