hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yang li » yang lin, yang yi, tang li
yang xi » yang yi, yang jui
li hua » li hui, lu hua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang li hua gene ((yang di) OR (yang xi)) ((hong ghi) OR (hong hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang li hua gene ((yang di) or (yang xi)) ((hong ghi) or (hong hai)) ;*.
