Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
yang cindy » yang mind
yang jui » yang judy, yang di, yang yi
yang jin » yang jie, yang jun, ying jin
yang xi » yang di, yang yi
hong ng » hong kong, hong jong, hong hong
hai » hadi, haji, hari

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 xi) OR (yang jui)) human gene ((yang cindy) or (yang jin)) ((hong ng) or (dang hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang xi) OR (yang jui)) human gene ((yang cindy) OR (yang jin)) ((hong ng) OR (dang hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang xi) OR (yang jui)) human gene ((yang cindy) or (yang jin)) ((hong ng) or (dang hai)) ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yang xi) OR (yang jui)) human gene ((yang cindy) or (yang jin)) ((hong ng) or (dang hai)) ;*.
