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 jui » yang judy, yang xi, yang yi
yang jie » yang jin, yang xi, yang yi
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, nan yan, wai yan
sar » sara, star, saur

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 jui) OR (yang di))) OR (yang jie)) ((kong siu) OR (kong sar)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan liang kang chen ((((yang jui) or (yang di))) or (yang jie)) ((kong siu) or (kong sar)) ;*.
