hua gene » human gene, a gene, hua ren
yang thi » dang thi, yang chik, yang di

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

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