Perhaps you should try some spelling variations:
gene yang » gene bank
yang amin » yang jin, yang lin, yang mind
amin hong » min hong, among hong, tin hong
yang yao » yang yang, wang yan, yang fan
hong hai » shang hai, zhong tai, dang hai
yang yi » yang xi, yang jui
a gene » a genre, a gender, a gentle

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: dong ((((yang yi) OR (yang di))) OR (yang yao)) a gene yang amin hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((((yang yi) OR (yang di))) or (yang yao)) a gene yang amin hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((((yang yi) OR (yang di))) or (yang yao)) a gene yang amin hong hai ;*.
