hua gene » human gene, a gene, hua ren
gene yan » gene bank, ren yan, see yan
wong sau » wong sam, wong siu, wong shiu
hong hai » shang hai, zhong tai, dang hai
yan jiu » yang jie, yang jin, pang jiu
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan asia) OR (dan asia)) hua gene yan jiu ((((wong sau) or (kong sar))) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan asia) OR (dan asia)) hua gene yan jiu ((((wong sau) OR (kong sar))) OR (hong hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan asia) OR (dan asia)) hua gene yan jiu ((((wong sau) or (kong sar))) or (hong hai)) ;".
• Adding a wildcard symbol may retrieve word variants: wang ((yan asia) OR (dan asia)) hua gene yan jiu ((((wong sau) or (kong sar))) or (hong hai)) ;*.
