Perhaps you should try some spelling variations:
yan chang » yuan chang, han chang, yan zhang
chang ann » chang min, chang won, chang yun
yan clan » yan guan, yan yuan
das clan » das bilan, das cern
ann hong » amin hong, wang hong, tan hong
yan kun » yan guan, yan yuan
nan yan » nan ya, wang yan, qian yan
hong il » jong il, hyoung il, honig ii

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: twinn ((das land) OR (((((yan clan) OR (das clan))) OR (yan kun)))) nan yan chang ann hong il ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "twinn ((das land) or (((((yan clan) OR (das clan))) or (yan kun)))) nan yan chang ann hong il ;~".
• Adding a wildcard symbol may retrieve word variants: twinn ((das land) or (((((yan clan) OR (das clan))) or (yan kun)))) nan yan chang ann hong il ;*.
