Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
yan liang » yang liang, wang liang, you liang
liang tan » liang dan, liang sun, wing tan
wong laid » wong lai, kong land
tan rene » juan rene, tan jee, tan kee
yang jui » yang yi
yang xi » yang yi

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: zhang yan liang tan rene ((((yang jui) OR (yang di))) OR (((yang judy) OR (yang xi)))) wong laid ;~.
• Adding a wildcard symbol may retrieve word variants: zhang yan liang tan rene ((((yang jui) or (yang di))) or (((yang judy) or (yang xi)))) wong laid ;*.
