han being » fun being, han heung, human beings
yan yuan » yan guan, fang yuan, nan yan
yi cheng » yi chen, yu cheng, xi cheng
wan yan » wang yan, nan yan, wai yan
yuan yi » yuan li, yuan zi, yuan fei

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: wan yan yuan yi cheng ((((han being) OR (human being))) OR (when being)) among (shin OR sein) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yuan yi cheng ((((han being) OR (human being))) or (when being)) among (shin or sein) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yuan yi cheng ((((han being) OR (human being))) or (when being)) among (shin or sein) ;*.
