dan yang » daun yang, tan yang, yang yang
hua gene » human gene, a gene, hua ren

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) or (dan yang))) or (wang yang)) ya hua gene yang ((jin hong) OR (jin song)) ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (dan yang))) OR (wang yang)) ya hua gene yang ((jin hong) OR (jin song)) ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) or (dan yang))) or (wang yang)) ya hua gene yang ((jin hong) OR (jin song)) ghi ;*".
