Perhaps you should try some spelling variations:
kin keong » king kong, min jeong
gene sang » lee sang, gene bank
yan yang » yang yang, yao yang, dan yang
yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
tin hong » tan hong, kia hong, thi hong
wan yan » wang yan, nan yan, wai yan

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: wan yan yang hua gene sang ((kin keong) OR (tin hong)) ghi ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan yang hua gene sang ((kin keong) or (tin hong)) ghi ;*.
