Perhaps you should try some spelling variations:
gene yang » gene bank
yang lin » yang jin, wang lin, yang liang
hua gene » human gene, a gene, hua ren
yang min » yang mind, yang jin, tang min
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yang li » yang di, yang xi, yang yi

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 lin) OR (yang li)) hua gene yang min ((hong ghi) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang lin) OR (yang li)) hua gene yang min ((hong ghi) OR (hong hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang lin) OR (yang li)) hua gene yang min ((hong ghi) or (hong hai)) ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yang lin) OR (yang li)) hua gene yang min ((hong ghi) or (hong hai)) ;*.
