hong than » hong tan, long thanh
yan than » van thanh, yan zhang, yan clan
hong hai » shang hai, zhong tai, dang hai
nan hua » wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) ((nan hua) OR (tan hua)) rents yan than ((hong than) OR (hong hai)) ;*.
