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
kong saur » kong sar, kong your, wong sau
yang jie » yang jin, yang jui, yang yi
kong siu » kong eiu, wong siu, dong sin
nan yan » nan ya, wang yan, qian 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: nan yan liang kang chen ((((yang xi) OR (yang di))) OR (yang jie)) ((kong siu) OR (kong saur)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan liang kang chen ((((yang xi) or (yang di))) or (yang jie)) ((kong siu) or (kong saur)) ;*.
