Perhaps you should try some spelling variations:
gene yang » gene bank
kong star » kong sar
lang yan » wang yang, zhang yan, yang yang
hua gene » human gene, a gene, hua ren
yang jun » yang jui, pang jun, yang jin
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
tan hua » tuan hua, wang hua, tan chia

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