Perhaps you should try some spelling variations:
gene yang » gene bank
zhong tai » zhong zhi
yang kao » yang yao, yang fan
yang min » yang mind, yang jin, tang min
hong hai » shang hai, dang hai, hong a
yang ka » yang fan, yang yao
a gene » a genre, a gender, a gentle
tan » than

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang ka) or (yang kao)) a gene yang min ((((zhong tai) OR (hong hai))) or (hong tan)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang ka) OR (yang kao)) a gene yang min ((((zhong tai) OR (hong hai))) OR (hong tan)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang ka) or (yang kao)) a gene yang min ((((zhong tai) OR (hong hai))) or (hong tan)) ;*".
