hua gene » human gene, a gene, hua ren
yang lin » yang jin, wang lin, yang li
lin chun » lin chih, lee chun, lin tun

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wing or wan) ((yanling yang) OR (yang yang)) hua gene yang lin chun g ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR wan) ((yanling yang) OR (yang yang)) hua gene yang lin chun g ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or wan) ((yanling yang) OR (yang yang)) hua gene yang lin chun g ;*".
