Perhaps you should try some spelling variations:
yan ying » fan ying, ran ying, tan ying
ying hua » ming hua, wang hua, ying zhu
hua gene » human gene, a gene, hua ren
yang jie » yang jin, yang di, yang jui
wong sam » wong sau, wong lai, von sam
wong siu » wong shiu, kong siu, wong sau
yan jiu » yang jin, pang jiu
wang » wing, wan, lang

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: wang yan ying hua gene ((yan jiu) OR (yang jie)) ((((wong sam) OR (kong sar))) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ying hua gene ((yan jiu) or (yang jie)) ((((wong sam) OR (kong sar))) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ying hua gene ((yan jiu) or (yang jie)) ((((wong sam) OR (kong sar))) or (wong siu)) ;*.
