Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
wang yang » wang yan, wang liang, wang yanling
gene hong » eng hong
gene one » gene clone, gene gene, gene we
hong sau » hong paul, kong sar, hong seo
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, 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: yuan wang yang xi ((gene hong) OR (gene one)) thi ((hong sau) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang yang xi ((gene hong) or (gene one)) thi ((hong sau) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang yang xi ((gene hong) or (gene one)) thi ((hong sau) OR (wong sau)) ;*.
