Perhaps you should try some spelling variations:
wang shiyong » wang hyoung
hua gene » human gene, a gene, hua ren
yang jin » yang jie, yang jun, ying jin
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
yan hua » tan hua, ya hua, wang hua
yan jiu » yang jie, pang jiu

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