Perhaps you should try some spelling variations:
yang yaong » yang yang, wang yang, wang yong
does human » das human, does humanity, models human
des human » das human, des humains, des humanen
bone yang » dong yang
jin keong » kin keong, jin kang, jin kyung
keong ghi » hong ghi
yang jin » yang jie, yang jun, ying jin

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yaong ((does human) OR (des human)) bone yang jin keong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: yang yaong ((does human) OR (des human)) bone yang jin keong ghi ;*.
