Perhaps you should try some spelling variations:
yan chang » yuan chang, han chang, yan zhang
chang run » chang yun, chang hsun, chang ann
tan yang » dan yang, tao yang, wang yang
tan ying » fan ying, ran ying, tan hong
tan yong » tan hong, tan kong, wang yong
jin song » jie song, john song, jin ying
kim song » kim young, kim eung
wang » wing, wan, lang

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 yan chang run ((((tan yang) OR (tan ying))) OR (tan yong)) ((jin song) OR (kim song)) sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan chang run ((((tan yang) OR (tan ying))) or (tan yong)) ((jin song) or (kim song)) sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan chang run ((((tan yang) OR (tan ying))) or (tan yong)) ((jin song) or (kim song)) sar ;*.
