yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
hong ng » hong kong, hong jong, hong hong
xi hua » xie hua
li hua » li hui, lu hua

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