Perhaps you should try some spelling variations:
gene yang » gene bank
ying yang » yang yang, yin yang, ying chang
kim eung » kim young, kim song
yong yan » yang yang, dong yang, yong yoon
xi gene » i gene, iii gene
li song » li cong, kim song, jie song
li rong » yi rong, li cong, shi rong

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yong yan) or (ying yang)) xi gene yang ((((li song) OR (li rong))) or (kim eung)) ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yan) OR (ying yang)) xi gene yang ((((li song) OR (li rong))) OR (kim eung)) ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) or (ying yang)) xi gene yang ((((li song) OR (li rong))) or (kim eung)) ghi ;".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yan) or (ying yang)) xi gene yang ((((li song) OR (li rong))) or (kim eung)) ghi ;*.
