Perhaps you should try some spelling variations:
cheng han » chen hao
wong laid » wong lai, kong land
yang yue » wang yue, yang yi, wong yue
yang yun » yang jun, tang yun, yang yang
yang jui » yang judy, yang di, yang xi
dai wong » dr wong
han dai » zhang dai, bang dai, tran dai
hong » long

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hong tan ((((((yang yue) OR (yang yun))) or (wang yan))) or (yang jui)) cheng han dai wong laid ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hong tan ((((((yang yue) OR (yang yun))) OR (wang yan))) OR (yang jui)) cheng han dai wong laid ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hong tan ((((((yang yue) OR (yang yun))) or (wang yan))) or (yang jui)) cheng han dai wong laid ;*".
